Here Today, Gone From the Map: Britain's Street Markets and the Location Data Blind Spot Costing Local Economies Dearly
On any given Saturday morning in towns from Bury to Barnstaple, thousands of traders set up stalls, erect canopies, and conduct hundreds of thousands of transactions with customers who have specifically sought them out. These are not marginal economic activities. Britain's street markets collectively turn over billions of pounds annually, employ tens of thousands of people, and serve as anchors for the footfall that sustains surrounding fixed-premises businesses. They are, by any reasonable measure, significant components of the local economic landscape.
They are also, for the purposes of Britain's official geospatial infrastructure, effectively invisible.
This invisibility is not a minor data quality issue. It represents a structural failure in the way Britain records and analyses its economic geography — one that distorts investment decisions, undermines local authority planning, and makes it impossible to measure, with any precision, the true economic contribution of an entire sector of commerce.
The Architecture of Official Absence
Britain's primary geospatial datasets for economic activity are built around a model of fixed, addressed premises. The Valuation Office Agency's rating lists, from which most commercial property data is derived, record businesses at permanent addresses. Companies House registration data is anchored to registered office addresses. The Land Registry records transactions against title numbers attached to defined land parcels. Each of these systems was designed for a world in which economic activity happens in buildings — and in that world, they function reasonably well.
Street traders, market stallholders, and pop-up vendors do not fit this model. A stallholder operating on a weekly market may have a business registration, a tax reference, and a bank account, but their trading location is not an address in any sense that the standard geospatial infrastructure can accommodate. They trade on a pitch — a temporary allocation of public space, often defined only by a chalked number on a flagstone or an entry in a paper pitch register held by a market superintendent.
That pitch has a physical location, a precise set of coordinates that could, in principle, be recorded, geocoded, and incorporated into a unified dataset. In practice, it almost never is. Market pitch data, where it exists at all, is typically held in local authority spreadsheets or legacy database systems that are neither standardised nor publicly accessible. The result is a category of economic location that generates real footfall, real revenue, and real employment, but that appears in no national dataset, informs no investment model, and contributes nothing to the official picture of where Britain's economic activity takes place.
What Footfall Analysis Cannot See
The consequences of this blind spot are most clearly visible in the retail footfall data that local authorities and Business Improvement Districts use to assess the health of town centres and justify regeneration investment. Footfall sensors — whether pedestrian counters, mobile device signals, or camera-based systems — can measure the volume of people passing through a given point. What they cannot reliably distinguish is whether those people are present because of a permanent retail offer, or because a weekly market has drawn them to the town centre that day.
This matters enormously for investment decisions. A town centre that appears, from footfall data alone, to perform strongly on market days but weakly on other days may be diagnosed as having a structural retail problem when it actually has a structural data problem: the market that drives its weekly peak is simply not visible in the datasets being analysed. Conversely, a proposal to relocate or reduce a market — perhaps to free up space for a permanent development — may be assessed against footfall evidence that systematically undervalues the market's contribution, because that contribution is not captured in the data.
The same blind spot affects the broader economic intelligence that feeds into local industrial strategies, levelling-up assessments, and high street regeneration programmes. When the Office for National Statistics produces estimates of retail employment, when the British Retail Consortium analyses trading patterns, or when a local enterprise partnership maps the economic assets of its area, informal traders are largely absent from the underlying datasets. The picture that emerges is systematically incomplete — and the policy responses it generates are calibrated to a version of the local economy that does not fully exist.
The Regulatory Tangle
There are structural reasons why informal trading has resisted integration into standard geospatial frameworks, and they are not all technical. Street markets in Britain operate under a complex and inconsistent regulatory patchwork. Some markets operate under Royal Charter or ancient statutory authority; others are licensed by local authorities under the Food Act 1984 or the Local Government (Miscellaneous Provisions) Act 1982; others occupy grey areas of permissive use or tolerated informality that resist precise legal characterisation.
This regulatory fragmentation means that responsibility for recording and managing market trading data is dispersed across dozens of different local authorities, each applying its own definitions, its own licensing categories, and its own data management practices. There is no national register of street markets, no standardised pitch identifier, and no mechanism by which the aggregate picture of informal trading activity can be assembled from its constituent parts.
The contrast with the formal property sector is instructive. Every commercial premises in England and Wales has a Unique Property Reference Number, assigned and maintained by Ordnance Survey, that provides a stable geographic identifier linking rating data, planning records, energy performance certificates, and a range of other datasets. No equivalent identifier exists for a market pitch — and without such an identifier, the data integration that makes the formal property sector legible to analysts and planners simply cannot happen for informal trading.
The Case for a Street Trading Spatial Register
The technical barriers to improving this situation are not insurmountable. A national register of licensed street trading locations — recording the geographic coordinates of market sites, the temporal patterns of their operation, and the number of pitches each site accommodates — would require relatively modest investment in data collection and standardisation. Several local authorities have already developed digital pitch management systems as part of broader smart city initiatives; the challenge is to aggregate and standardise these local efforts rather than to build from scratch.
Such a register would not need to capture every informal transaction — that would be neither feasible nor desirable. But it would need to record the geographic footprint of legitimate, licensed trading activity with sufficient precision to allow it to be incorporated into footfall models, economic impact assessments, and land use analyses. The difference between knowing that a market exists somewhere in a town centre and knowing its precise location, operating hours, and approximate scale is the difference between a data point and actionable intelligence.
Mapping the Economy as It Actually Exists
Britain's town centres are under sustained pressure. The structural shifts in retail behaviour that accelerated during the pandemic have left many high streets searching for a new economic identity. Street markets — flexible, low-barrier, community-rooted — are increasingly recognised as part of the answer, not merely as heritage curiosities but as genuine economic engines capable of attracting footfall and sustaining local supply chains.
Realising that potential requires understanding it. And understanding it requires mapping it. The geospatial infrastructure that Britain uses to describe, analyse, and plan its economic geography must be capable of seeing the economy as it actually operates — not only in the permanent, addressed, rated premises that fit neatly into existing data models, but in the temporary, mobile, pitch-based trading that has been part of British commercial life for centuries and shows no sign of disappearing.
Until that infrastructure is built, a significant and vibrant portion of Britain's economic landscape will remain, in the most literal sense, off the map.
