Does food insecurity lead to greater health inequalities in Oxfordshire?

Researchers from the Consumer Data Research Centre have been working in partnership with Good Food Oxfordshire (GFO) to investigate the spatial association between food insecurity risk and health outcomes in Oxfordshire.

Food insecurity is a growing concern in the UK and one that around 9 million adults suffered from last June (2023).

Food insecurity, which could lead to both obesity and malnutrition, is also a major driver of health inequalities and a risk factor for severe health outcomes (diabetes, hypertension, stroke, heart disease, and several cancers).

The purpose of this project was to produce data driven resources to empower Good Food Oxfordshire (GFO) to support and promote a healthy, sustainable, and fair food system in areas where its absence is exhausting NHS resources the most.

“The Priority Places for Food Index in general, and this research in particular, are really useful for us in help setting priorities and metrics for the Oxfordshire Food Strategy, which has local plans for each District. PPFI is a key metric, and the dashboard provides an easy-to-access, easy-to-explain visualisation for discussion with expert and non-expert alike.”

Fiona Steel, Manager, Good Food Oxfordshire

The data

This project combined qualitative insights from Good Food Oxfordshire (GFO), with quantitative data on food insecurity risk and various health outcomes to pinpoint areas where supporting the food system could most reduce health inequalities. 

Visualising the data

One of the outputs of this project was a Power BI dashboard – an accessible, intuitive, and responsive tool that empowers policy- and decision-makers to identify Oxfordshire areas where food insecurity could aggravate health inequalities.

You can find further detail on the data and methods in the full case study: Does food insecurity lead to greater health inequalities in Oxfordshire?

Using insights to target support

Policymakers in GFO’s network will use the dashboard to help make strategic decisions on where to focus their efforts to best support the food system.  The dashboard enables them to prioritise specific levers (i.e., addressing the most salient food insecurity risk factors) for each area, to improve health outcomes and reduce the prevalence of specific health conditions.

  • Tackling income deprivation in Blackbird Leys and Greater Leys (among the 20% most deprived areas in England) could significantly reduce the prevalence of child obesity (by 0.7% at the reception year and 1.8% at year six) and Type 2 diabetes (by 1.6-1.7%), with each decile shift in the socio-demographic barriers PPFI dimension.

  • Initiatives to make energy more accessible, affordable, and efficient for the population in Barton, Churchill, and Sandhills (whose areas are among the 20% most deprived in England) could significantly reduce child obesity at the reception year (by up to 0.9%) and year six (by up to 1.7%), with each decile shift in the fuel poverty PPFI dimension.

  • The reinforcement of family food support schemes in Churchill, Iffley, Littlemore, and Rosehill (whose areas are among the 20% most deprived in England) is expected to reduce the prevalence of child obesity (by 1.8% at the reception year and 3.6% at year six) and diabetes (to a lesser extent—by 0.3-0.4%).

Poor diet is a leading cause of death in the United Kingdom and around the world.

In this webinar Professor Michelle Morris discusses how methods to collect quality dietary information at scale for population research are time consuming, expensive and biased.

Novel data sources, such as supermarket sales transactions and loyalty card data, offer the potential to overcome these challenges and better understand population dietary patterns.

Michelle shares examples of how these data can be used to better understand population level dietary patterns, how these compare with national recommendations, how they vary by sociodemographic characteristics and what we can do to change them.

Investigating the impact of HFSS Legislation

Blurred image of a supermarket aisle - products not distinguishable but indicating source of consumer data

Since 1 October 2022, new legislation for England restricts the placement of some food and drink products High in Fat, Sugar and Salt (HFSS). 

Products such as confectionery can no longer be placed at store entrances, ends of aisles, or at the checkout in large retail stores and their online equivalents.

The introduction of the legislation prompted the food industry to implement significant changes, including store layout changes by retailers and product reformulation efforts by manufacturers. 

Understanding the impact of HFSS Legislation

Eighteen months on from the legislation’s implementation, a team of researchers led by Professor Michelle Morris, and supported by IGD, will be evaluating the impact of this legislation.

The team are working with ASDA, Morrisons, Sainsbury’s and Tesco, who collectively represent 65%* of supermarket sales, to understand the impact of the HFSS legislation restricting location placement of HFSS products.

The analysis, conducted by researchers at the University of Leeds as part of the DIO Food project, will answer the following research questions:

(1) What happened to HFSS product sales after introduction of the policy?

(2) What happened to the retail product portfolios after introduction of the policy?

(3) Were impacts of the HFSS legislation equitable across different sociodemographic groups across the country?

(4) Has the HFSS legislation led to healthier overall purchasing using Eatwell guide as a metric?

These questions will be answered using store level sales data, supplemented by contextual information collected in interviews and surveys with the retailers and customers.

Read the protocol on Open Science Framework.

Prof Michelle Morris said: “We really are delighted to be working with these four major retailers to evaluate such a significant policy and look forward to sharing findings once available”

Utilising CDRC Products

The sales data provided by the retailers will be for stores selected across deciles of our Priority Places for Food Index (developed in collaboration with Which? in 2022) to allow us to investigate whether the legislation has impacted different communities equally.

The researchers will analyse the impacts of the implementation from a health and sustainability perspective, using the Eatwell Guide.

The team will also use innovative data products created by CDRC’s Dr Fran Pontin (Eatwell algorithm) and Dr Victoria Jenneson (Nutrient Profile Model Calculator) in their analysis, providing insight that cannot be found elsewhere.

Building on previous real-life behaviour change trials

This research is part of a broader UKRI Transforming UK Food Systems academic collaboration, led by Professor Alex Johnstone at the University of Aberdeen, the Diet and Health Inequalities (DIO food) project.

The work package 6 partnership builds upon the University of Leeds ongoing programme of real-life behaviour change trials with IGD to build evidence on what works, and doesn’t, to shift consumers to healthier and more sustainable diets.

Dr Victoria Jenneson said “Applying our CDRC data products at scale will offer a unique perspective on the nuances of the legislation, such as equity. We are excited to uncover impacts on HFSS sales, and on changes to product portfolios too.”

We are looking forward to learning more from this interdisciplinary, cross sector team of Prof Michelle Morris and Dr Victoria Jenneson from the School of Food Science and Nutrition and Dr Alison Fildes and Dr Alice Kininmonth from the School of Psychology at University of Leeds alongside ASDA, Morrisons, Sainsbury’s and Tesco, IGD and wider DIO Food team.

Understanding speed behaviours, speed limit compliance, and road characteristics in Leeds

Urban Mobility Image

Understanding speed behaviours, speed limit compliance, and road characteristics in Leeds

Research by Long Chen and Ed Manley uses data provided by Compass IoT to provide an overview of speed behaviours, speed limit compliance and road characteristics in Leeds.


Importance of Speed behaviours

Speed behaviours of vehicles are important facets in transport planning, road safety and urban livability. There are also several critical social and environmental aspects linked with speed behaviors, e.g., excessive carbon emissions.

Speed limit compliance

Adherence on posted road speed limits would have positive effects on traffic safety, road capacity, and traffic congestion, etc.

Measures of speed behaviours

Prior studies are often conducted by questionnaire survey; limited sites observation; and simulated driving environment to capture vehicle speeds and driver’s speed behaviours.

Study Data

For this study we used vehicle trajectories with travel speeds and acceleration indicators, provided by Compass IoT. This dataset is available for access on the CDRC data repository. The dataset is available for several UK cities. The data used in this study focuses on Leeds only, and contains 3,008,530 individual point records within 44,321 unique journeys, during October 2023.

The Gaps

• There is an absence of studies capturing speed behaviours and characteristics for large volume of vehicle trajectories on a larger geographical scale.

• There is a lack of knowledge between speed behaviours, road characteristics and urban environment at finer-granularity.


• Measures of speed selection (including adherence with speed limit) and acceleration behaviours (e.g. slow / rapid) extracted

• Mean measures computed over time (hour, day) and by road segment

• Quantiles used to select boundaries for assessing acceleration and deceleration behaviours, including extreme behaviours (Q1, Q4)


Speed behaviours over time

Temporal variation of speed, acceleration, deceleration in Leeds show that fastest speeds occur during the night-time; Rapid acceleration and deceleration events are more common during the daytime than at night

            Figure 1: Temporal variation of speed by quartiles, Figure 2: Temporal variation of Acceleration, Deceleration by quartiles

Speed selection and adherence over space

Lower speeds observed in. dense road networks and urban areas; Higher speeds observed on highways and major roads.

Figure 3: Average speed at Road segments               Figure 4: Adherence rate at Road segments

Better adherence in dense road networks, and urban areas; Worse adherence on 20mph zones and pedestrianised areas

Acceleration, and Deceleration

Average acceleration, deceleration maps illustrate that higher acceleration and deceleration road segments are located at main roads, particularly around junctions, and suburban residential areas

Roads segments with extreme acceleration, and deceleration behaviours usually accommodate in dense road network, and junctions of road networks.


• Results show distinctive speed limit adherence, acceleration, and deceleration characteristics in road hierarchy and urban areas, highlighting the potential for analysing speed behaviours in urban settings.

• Specifically, lower speed limit adherence behaviours generally occur in roads with lower speed limit, and minor and local roads, in suburban residential areas; Extreme acceleration and deceleration behaviours are found in dense road network, and entries and exits of major roads (e.g. motorways).

• The exploration of speed behaviours opens up new opportunities for considering urban mobility and design, and opportunities for understanding the latent mechanisms and factors influencing these behaviours.

Use the data

Was there a Banksy price bubble during COVID-19?

Was there a Banksy price bubble during COVID-19?

A recent study from Dr Stephen Clark explores the change in price of limited-edition Banksy prints over the last decade – we asked him to share his thoughts on whether there was a Banksy price bubble during COVID 19.

Here at the CDRC we work with industry partners to make consumer related data available to trusted researchers, whose work can help us to understand important social challenges. In this piece here we are looking at a particularly niche consumer and their behaviour during an extra-ordinary period in recent history.

The consumers are those who purchased limited edition prints at auction by the street artist Banksy, and the time period is during the global COVID-19 pandemic. In particular, did a pricing bubble occur for his works during this period?

BANKSY | TROLLEYS, non-commercial use https://pestcontroloffice.com/use.asp

Why Banksy?

Banksy is probably the world’s most famous street artist. His true identity is unknown but it is believed that he started his street work during the early 90’s in the English city of Bristol.

BANKSY | STOP AND SEARCH, non-commercial use

He is best known for his satirical humour and takes on modern life, mixing together commercial, political and contemporary images to provide social commentary.

His works consist of one-off originals and, in the late 90’s and early 2000’s, he started to produce a limited number of screen prints in signed and unsigned editions. These were eagerly purchased, initially by an enthusiast class of customer, but, as his popularity and value increased, latterly by an investor class. On the primary market these prints would initially sell for less than £500.

The data – Banksy Auction Results

In this study use is made of the database of Banksy auction results maintained by the www.banksy-value.com web site. This web site has catalogued the details of Banksy works sold at auction houses all over the worlds since the mid 90’s.

The limited edition prints in this database are used to examine what features of a print influence the selling price, and to what extent these prices may have been affected by the COVID-19 pandemic

The impact of COVID-19 on the sales prices of Banksy limited edition art works

The www.banksy-value.com web site maintains a tracker index for the sales prices of Banksy limited edition art works and this begins to show the impact and the extent of COVID-19 on his market.

From this chart it is clear that there was a steep rise in the sales price of Banksy prints starting in early to mid-2020, and that in recent months the prices have dropped considerably to back where they were at the start of the pandemic.

But does this meet a definition of a bubble? A bubble in asset classes, such as stocks and shares, housing, crypto-currencies and even tulips, is composed of many stages: Expectation; Boom; Euphoria; Profit-taking and Panic.

The start of the COVID-19 pandemic was an unprecedented time in recent history. Many people were unsure of their futures, both health wise and economically.

This uncertainty could have gone two ways in the Banksy art market, either people would be desperate to sell his works to get cash for daily expenses and his prices would crash, or they could seek out opportunities to invest for the future and look to Banksy works to provide a safe – and accruing – haven for any savings or credit. Clearly from this figure it was the latter case.

In the hedonic regression model for Banksy prints, a number of factors were controlled for before examining the impact of COVID-19. These included the particular image, if the print was signed by Banksy, the condition of the print, and the size of the edition. The reputation of the auction house and the location of the sale were also used along with a linear time trend. To capture the impact of COVID-19 a series of eight half year 0/1 variables were used to measure this impact and by using a random effects model, the impact was allowed to vary by the image. This would allow an assessment of whether the price of some images were impacted by COVID-19 more than others.

Banksy | Game Changer, non-commercial use https://pestcontroloffice.com/use.asp

Firstly the extent of the COVID-19 shock is shown in this chart. In the years prior to the second half of 2019, the long run cost of a Banksy print at auction was about £10k, but by the end of 2019 the price was more in the region of £25k. These prices quickly rose, by the end of 2020 tripping to around £75k within a year. Such prices were not sustained however, and starting in the second half of 2021 the prices began to fall.

Some prints were affected more than others. The iconic ‘Flower Thrower’ (aka ‘Love is in the Air’) print nearly quadrupled in price at the peak of the bubble, whilst some more mainstream prints showed a more modest doubling in prices.

Banksy joins Warhol and Hirst with the dubious honour of having his own bubble.

It is the contention of the article that accompanies this piece that there was a bubble in the price of Banksy prints sold at auction during the COVID-19 pandemic and that the size of the bubble inflated prices to around 3 time their pre-pandemic levels. Prices had by early 2023 returned to the levels seen before the pandemic. The size of the bubble also varied by the print image.

Banksy has now joined other artists such as Warhol and Hirst with the dubious honour of having his own bubble, and he has lost his mystic that his works would always hold their value.

How do we lower the barriers to understanding sustainable diets?

How do we lower the barriers to understanding sustainable diets?

It is well publicised that a societal shift towards a more sustainable diet would help to limit global warming, but how easy is it for individuals to understand what a more sustainable diet might look like in practice?

The Paris Agreement (UNFCCC, 2015) sets long term goals to guide all nations to substantially reduce global greenhouse gas emissions and to pursue efforts to limit global temperature increase to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change.

Recent research from CDRC’s Dr Susan Lee and colleagues from the Centre for Climate Change and Social Transformations, published in Frontiers in Sustainable Food Systems, explores how we can use complex data from Integrated Assessment Models (IAMs) to identify dietary shifts that align with these goals, then simplify through visualisation to help people make informed choices about possible lifestyle adjustments.

What is an Integrated Assessment Model?

An Integrated Assessment Model (IAM), such as the IMAGE IAM used in this study, is a model that simulates interactions between climate, economy, society and the biosphere to evaluate climate change impacts and develop mitigation policies.

Traditional IAM outputs are incredibly useful to help us understand the impact of dietary shifts, but the complexity of the data and the need for detailed analysis can make them largely inaccessible beyond the research community.

This research explores how visualisation can be used to make these insights more accessible to both diet, nutrition, and sustainability professionals and the wider public.   

Translating IAM outputs into accessible visualisations

The researchers systematically examined the impact of modelled changes in food demand on regional diets and dish visualisation. 

Their approach involved preparing and interpreting IAM scenario data, establishing food consumption baselines for Sweden, China the UK and Brazil and applying the Diets, Dishes, Dish Ingredients (DDDI) framework* to analyse shifts in food consumption patterns.

Visualising current and potential dishes

They then worked with a designer to create proportional visual representations of current dishes and potential dishes for 2050 to highlight and better communicate the balance of plant and meat-based foods in potential future diets.


Current dish: (Köttbullar) include meatballs comprising of beef and pork which are served with gravy, mashed potatoes, lingonberries, and green beans (A)

Future dish: Meat replaced by lentils, nuts, and seeds, while the proportion of vegetables expands to occupy half the dish by 2050 (B)


Current dish: Sweet and Sour Pork dish includes pork with pineapple, red and green peppers, and onions together with rice. (C)

Future dish: The pork is replaced by tofu (soy curd) (D)


Current dish: Chicken Korma consists of chicken, vegetables (onion, tomatoes, and a sprinkling of coriander) with rice (E)

Future dish: Chicken gradually replaced by pulses (chickpeas and lentils) with the introduction of broccoli to represent the increased vegetable proportion between 2020 and 2050 (F)


Current dish: Feijoada – the dish consists of pork, beef, and beans, and is accompanied by a slice of orange, salsa, pan-fried collard beans (leafy vegetable) with garlic, and rice (G)

Future dish: The 2050’s dish includes sweet potato (considered a staple like rice) and black-eyed peas (pulses) (H).


Overcoming barriers through better communication

Whilst there is still more work to be done in this area, this study represents an effort to make complex dietary transition data more accessible.

Visualisations, like the ones shown above, could be used by diet, nutrition, and sustainability professionals to aid discussions around dietary changes with different communities.  

Dr Susan Lee explains ‘We know that the shift in people’s diets will face barriers such as increased food costs, changes in habits and preferences, accessibility of plant-based foods and potential cultural and social barriers that may hinder the shift in diets to tackle climate change. However, the use of visual communication frameworks showcased in this research could help ease the transition to more sustainable diets within communities.’

Priority Places for Food – examples of high-priority neighbourhoods across England, Wales, and Scotland

Priority Places for Food – examples of high-priority neighbourhoods across England, Wales, and Scotland

The Priority Places for Food Index (PPFI), developed as a collaboration between the Consumer Data Research Centre (CDRC) and Which?, was launched in 2022 to identify neighbourhoods that are most vulnerable to increases in the cost of living and which are likely to be food insecure.  

In January 2024 we launched Version 2 of the index, providing the most up-to-date picture of food insecurity risk at neighbourhood level.  

In this post, Dr Fran Pontin and Dr Rachel Oldroyd highlight diverse examples of high-priority neighbourhoods across England, Wales, and Scotland, illustrating how various factors and barriers can converge to create a ‘perfect storm,’ resulting in households experiencing hunger or being unable to access a balanced, healthy diet.

For instance, there may be areas where families with young children are facing financial struggles and dealing with escalating food costs, leading them to turn to food banks to ensure their children are warm and well-fed.

Or, in rural areas where people have limited access to cars and poor local public transport, the ability to choose from a variety of food options and find the best deals is constrained. This limitation forces residents to rely on often more expensive convenience stores with a restricted selection of healthy and budget-friendly items. 

Alum Rock – Birmingham

Situated to the east of the city centre, Alum Rock is one of the most deprived wards in Birmingham, where 100% of the neighbourhoods in this area are classified as high priority places for food. This area has a young demographic, with 21% of the population aged 15 or under.

Therefore, presence of families and a related demand for family food support is particularly pronounced. Alum Rock is one of Birmingham’s most economically disadvantaged areas, with employment rates significantly below the city average.

Despite the presence of several supermarkets and convenience stores in the area, residents are likely to encounter substantial socio-economic barriers when attempting to access nutritious and healthy food. Moreover, this area reports high levels of fuel poverty, forcing many individuals to make difficult choices between heating and eating. 

Hainault – Redbridge

Hainault is a good example of a ward where no one neighbourhood is the absolute highest priority within a specific PPFI domain when compared with the rest of England.

Here, neighbourhoods rank around the top 30-40% most in need across all the Priority Places domains. When considered in combination, however, these relatively high socio-economic risk factors paired with relatively poor access to purchase food contribute to high risk in food insecurity.

Compared to the borough population at the previous census in 2011, Redbridge has seen an increase in the proportion of families with children, more adults working shorter hours, increased population density and an increase in the number of people renting in the 2021 census.

This means by updating the data included in the Priority Places for Food Index, as new data comes available, we have captured these local area changes to give the most informed picture of food insecurity risk. 

Norris Green – Liverpool

In the ward of Norris Green, Liverpool, all neighbourhoods bar one are in the top 20% of priority places across England and in need of support with food.

The ward of Norris Green demonstrates where socio-economic barriers paired with heating cost demands and reliance on additional food support have resulted in increased food insecurity risk.

We also see a discrepancy between fairly good proximity to supermarkets (i.e. there are lots of supermarkets nearby) but access to supermarket food via public transport or online delivery service is significantly poorer, suggesting that improving access to what is already there could be of benefit to this community.  

Llanasa and Trelawnyd – North Wales 

In the ward of Llanasa and Trelawnyd in North Wales we see a good example of the importance of considering the domains in different population contexts.

The ward overall is not particularly high priority compared to Wales as a whole (in the top 30-60%). However, access to both supermarket and non-supermarket food is poor due to limited outlets in the local area. This ward has a large population of older adults so this poor access to food choice risks becoming a barrier to healthy and affordable food for these groups.

Conversely, we see less reliance on family food support as there are fewer school aged children (compared to Wales on average).   

Canal Ward – Glasgow

In the Canal Ward of Glasgow, we see that some domains, such as the need for family food support are high across the ward whilst others such as socio-demographic barriers and access to supermarkets vary by neighbourhood. For example, towards the south of the Canal ward, towards Glasgow city centre, sociodemographic barriers are lower and access to supermarkets is better, making this neighbourhood a lower priority place compared to the rest of the ward, illustrating how the factors combine to make an area high priority.

Newsome – Kirklees

Newsome, located to the South of Huddersfield town centre in Kirklees, is a good example of a traditional ‘food desert’ as 81% of the neighbourhoods in this ward have limited supermarket access.

Compared to other areas, the average distance to a supermarket and the average time taken to travel to a supermarket from this area via public transport is high. 40% of households in the area do not have access to a car or van so might find themselves struggling due to the lack of accessible supermarkets.

Compared to other priority areas, Newsome has lower need for family food support, and socio-demographic barriers do not contribute as much to the area’s level of priority for support.  

Little Horton – Bradford

Little Horton, to the South of Bradford City centre, is the second most deprived ward in the city. 

Therefore, unsurprisingly, we note substantial socioeconomic barriers which limit access to healthy and nutritious food.

Little Horton has the highest percentage of children aged under 16 compared to other areas in Bradford and the need for family food support is high.

We see elevated levels of fuel poverty compared to other areas, and unemployment currently lies at 30%, well above the national average of 4.3%.

Little Horton is also an area of priority for ecommerce, so residents may struggle to buy groceries online, which is problematic for people who are unable to travel to the supermarket.  

Eilean a’cheo – Scottish Highlands 

Eilean a’cheo is a ward located in the Highland of Scotland and includes the islands of Skye and Raasay.

All 13 of the neighbourhoods within this ward fall within the highest priority places for supermarket proximity due to their remote location.

Residents of Eilean a’cheo are likely to face barriers accessing food due to the distance to the nearest supermarket.

All neighbourhoods within this area are also high priority for fuel poverty, with residents paying on average 76% above the national average to heat their homes.

Eilean a’cheo is also a priority area for ecommerce. Therefore, there may be difficulty obtaining online grocery deliveries compared to other areas. 

How are you using the Priority Places for Food Index?

We’d love to hear how you are using the Priority Places for Food Index to better understand food insecurity risk in your area.

We always welcome suggestions from those using the tool to make it as useful as possible – please do get in touch with the CDRC Leeds team if you have any questions or recommendations.

Priority Places for Food Index – Version 2 Released

Priority Places for Food Index

The Priority Places for Food Index (PPFI), developed as a collaboration between the Consumer Data Research Centre (CDRC) and Which?, was launched in 2022 to identify neighbourhoods that are most vulnerable to increases in the cost of living and which are likely to be food insecure.  

In January 2024 we launched an updated version of the index, providing the most up-to-date picture of food insecurity risk at neighbourhood level.   

What is the Priority Places for Food Index? 

In 2022, 14% of households in the UK struggled to access a reliable source of healthy, nutritious and affordable food. However, statistics about food insecurity outcomes, such as those provided by the Trussell Trust, are not captured at individual or neighbourhood level, making it difficult to target specific areas.  

Using openly-available data, the Priority Places for Food Index allows food insecurity risk to be mapped at a local level, focusing on areas roughly 650 households in size, across all devolved nations.  

As the index uses seven different data domains, it can be used to identify areas that are a priority for different types of support and where that support needs to be targeted.

Across all nations of the UK, the PPFI is being used by policymakers, academics, charities, retailers, nutritionists, consumer groups, and educators in their efforts to reduce food insecurity.  Which? used the Priority Places for Food Index as part of their Affordable Food for All campaign, which calls on supermarkets to commit to clear pricing and better access to budget ranges that enable healthy choices and more offers for those who need them most.

What’s changed in this version of the Priority Places for Food Index?

Data have been updated across several of the seven PPFI domains. This includes new area socio-demographics, foodbank, and food retailer location data.  

Data relating to Free School Meal eligibility has also been updated to reflect the changing policy landscape and to address regional inconsistencies in policies. We now include all children in households of relatively low income, reflecting recommendations that the free school meal program be extended to all children in these households. Just this month, The Mayor of London, Sadiq Khan, extended the funding for universal free school meals as the cost-of-living crisis continues to hit families.  

Finally, in England and Wales, the Index has been updated to reflect the latest 2021 census neighbourhood boundaries (Lower layer Super Output Areas).  For the full details of the data update see the PPFI version two data profile.  

The Seven domains of the Priority Places for Food Index. 1. Proximity to supermarket retail facilities, 2. Accessibility to supermarket retail facilities, 3. Proximity to non-supermarket food provision, 4. Access to online deliveries, 5. Fuel poverty, 6. Socio-demographic barriers, 7. Need for family food support

Areas may look different to version one as a result of the new data incorporated or changes to neighbourhood boundaries. Because of these data changes we recommend that you don’t make comparisons between the versions.  If you would like to continue to use version one, you can find it here

You might also notice a few changes to some of the features within the dashboard. Following a year of engagement with charities, local and national government and commercial organisations using the tool we have made a few upgrades to the dashboard to improve the user experience. These tweaks include making it more accessible to those who use assistive technology and adding more detailed ‘how to’ guides on the web page. We have also improved the map navigability, adding a search bar that enables you to ‘zoom to’ your chosen local authority or region of the UK.
