Methodology for central London mapping

The CAZ and NIoD constitute non-standard geographies and as such no official statistics are produced on their population or characteristics.Data must therefore be created for the areas by aggregating from smaller geographies.

This report uses Lower Super Output Areas (LSOAs) and Major Super Output Areas (MSOAs). Business Register and Employment Survey (BRES), and population data are available at the LSOA level, IDBR data are available at the MSOA level.

Centre for London downloaded and analysed data from the BRES to map employment density. Employment data was used as opposed to employee data as the former includes both employees and working owners. The data include full, part-time, and self-employed workers as long as they are registered for VAT or Pay-As-You-Earn (PAYE) schemes. Working owners are typically sole traders, sole proprietors or partners who receive a profit share.

Centre for London also downloaded and analysed data extracted from the Inter Departmental Business Register (IDBR), which record the number of local units that were live in March of the year data were collected. Estimates are broken down by detailed industry. A local unit is defined as an individual site (for example, a shop) associated with an enterprise. It can also be referred to as a workplace, and there can be multiple units operating under the same enterprise (for example, multiple shops of one supermarket chain).

The method used to define the CAZ and NIoD area was twofold. LSOAs were allocated to the CAZ and NIoD if 0.5 or more of their total area fell within the London Plan area boundaries when modelled. MSOAs were then derived from the formulated list of LSOAs.

The CAZ and NIoD boundaries displayed on the maps are intended for illustrative purposes only.
