Store Catchment Report
The store catchment report shows who lives within a walk and a drive of a shop in England or Wales: residents, households, age, car ownership and occupations from Census 2021, a spending power indicator from ONS income figures for their councils, and how many shops of the same kind OpenStreetMap maps in each catchment, with the nearest one.
What You Give It
- The store: its postcode, or its outline drawn on a map or uploaded as a file. Every catchment is measured towards its centre.
- The kind of shop, from 28 types: supermarkets, convenience shops, bakeries, butchers, pharmacies, opticians, cafes, takeaways, pubs, hairdressers and more. Shops of the same kind count as the competition.
- Walk and drive times: up to three of each, from 5, 10, 15 and 20 minutes.
- Traffic: free-flowing at the speed limits, or busy times at about 60% of the speed limits.
What You Get
Walk and Drive Catchments
One area for each time, built on the street network towards the store, with the residents and households living inside.
Who Lives There
Age bands, the share of households with no car or van, and the share of residents aged 16 and over in managerial or professional occupations.
A Spending Power Indicator
Gross disposable household income per head for the councils the residents live in (ONS, 2024), weighted by where they live, and as a share of the UK average.
The Competition
How many shops of the same kind are mapped in each catchment, and the nearest one with its straight-line distance.

How It Works
Catchments are built as in Who can reach this place: towards the store on the OpenStreetMap network, roads cut at the time limit and widened into areas. Walking runs at 4.8 km/h; driving at each road's speed limit, or about 60% of it at busy times. A Census 2021 output area counts as inside a catchment when its population-weighted centre is inside it.
What Each Figure Is Made From
| Figure | Data |
|---|---|
| Residents and households | Census 2021 table TS001, ONS via Nomis |
| Age | Census 2021 table TS007A |
| Households with no car or van | Census 2021 table TS045 |
| Managerial and professional occupations | Census 2021 table TS062 (socio-economic classification) |
| Spending power | Gross disposable household income per head by council, ONS 2024 (provisional), weighted by where the catchment's residents live |
| Competing shops | Places tagged as the same kind of shop in OpenStreetMap, counted inside each catchment |
On the Public Site
The public site shows three real example runs made with the Bozmaps analysis engine on 8 November 2026: a supermarket in Radford, Nottingham, a bakery in Wycliffe, Leicester and a pharmacy in Arboretum, Derby. Each has its map, figures and full report. A new store needs the engine, so we run it for you.
A Supermarket in Radford, Nottingham
In the example run of 8 November 2026 (NG7 3LA), about 2,400 people lived within a 5-minute walk of the store and 17,800 within 15 minutes; about 160,000 within a 5-minute drive and 524,000 within 10 minutes. In the 10-minute drive area, 31% of households had no car and 28% of residents aged 16 and over were in managerial or professional occupations. Their councils' disposable income averaged £20,432 a head, 79% of the UK average (ONS, 2024), and OpenStreetMap showed 83 other supermarkets, the nearest 325 m away.

What It Can't Tell You
- Residents only: workers, students away from home, visitors and passing trade are not counted.
- Spending power is a council average weighted by where residents live, not measured for the catchment, and it is income, not spending in shops.
- Competing shops come from OpenStreetMap, which volunteers map: some shops are missing, some have closed, and the shop type is as tagged.
- Drive times are free-flowing unless the busy-times setting is used; parking and congestion are not included, and neither is public transport.
- The public site shows the three example runs; a catchment for a new store runs on the Bozmaps engine.
The tools are in preview: built and tested, not yet signed off as validated. They screen a place from public data and don't replace a survey or professional advice.
Questions
Something else? Ask us.
Can I run a catchment for my own store on the website?
Not on the public site. It shows three real example runs, each with its map and full report. A new store needs the Bozmaps analysis engine, so tell us the store, the kind of shop and the times you want, and we run it for you.
Is the income figure the income of the people in the catchment?
No. It is the ONS figure for disposable household income per head in each council the residents live in, weighted by how many of them live in each. It is an indicator for comparing places, and it measures income, not what people spend in shops.
How are competing shops counted?
From OpenStreetMap: every place tagged as the same kind of shop inside each catchment, with the nearest one and its straight-line distance. OpenStreetMap is mapped by volunteers, so check the count against what you know locally.
Does it count people who work nearby or pass by?
No. It counts residents from Census 2021. For a shop that relies on office workers, commuters or visitors, the resident count is a floor, not the whole market.
What kinds of shop can it compare?
28 kinds, from supermarkets, convenience shops, bakeries, butchers, greengrocers and delicatessens to pharmacies, opticians, hairdressers, cafes, restaurants, takeaways, pubs, off-licences, charity shops and bike shops.
