As the demand increases for statistics and data to measure the impact of the COVID-19 pandemic, we have had to change our data gathering and release practices, focussing efforts on priority analysis and statistics.

General description
This dataset provides data on the structure of enterprises active in Wales by industry (SIC 2007) and size-band , including estimates for the very smallest businesses that operate below the VAT threshold. The variables analysed are counts of the enterprises active in each area, together with related employment and turnover aggregates in each of the given industries and size bands, the latter being based on the number of UK employees in the enterprise as a whole.
Note that area breakdowns of the data are workplace based.

Data collection and calculation
The data given are based on enterprises with some activity in Wales or one of its sub-areas, regardless of the region of registration. In this context, an enterprise is taken to be an entire organisation, including its head office and all the individual UK sites, wherever they may be located. The region of the enterprise is usually based on the location of its head office, although the sites may be located in other regions. The figures given for employment and turnover for Wales or its sub-areas in this analysis relate only to the sites of the enterprises located in those areas.
In all cases, the size band of the enterprise is based on the number of UK employees (whether full-time or part-time) in the enterprise. This ensures that an enterprise employing 10,000 UK staff but only a handful in the area given is categorised as a large, and not a micro, enterprise.
The enterprises covered are all private sector enterprises (that is companies, sole-proprietorships, partnerships, private non-profit making bodies and mutual associations), plus public corporations and nationalised bodies. Local and central government organisations are excluded.
The data have been derived from a number of sources. The primary source is a detailed extract taken in March of each year from the Inter-Departmental Business Register (IDBR) maintained by the Office for National Statistics (ONS). This gives details of all enterprises active in Wales, including the UK employment and turnover and derived figures for the Welsh elements of employment and turnover (using information about the sites in each enterprise which are located in Wales). It also includes identifiers for industry (using the Standard Industrial Classification), geographical location and legal status of each enterprise, thus allowing the analysis given here.

Rounding applied
As all enterprise counts and employment aggregates in this dataset have been independently rounded to the nearest 5 and 100 respectivley, and all turnover aggregates independently rounded to the nearest million pounds, the figures may not add up exactly.
In order to avoid suppression of data due to disclosure control (which must occur for any aggregates based on less than 20 enterprises), some of the size bands have been presented in an aggregated form. These aggregated size bands have been chosen to limit the amount of aggregation whilst ensuring no data are suppressed.

Statistical quality
The IDBR covers a very high proportion of the employment and turnover in the UK, but because it excludes most of the very large number of smallest businesses that operate below the VAT threshold, its coverage in terms of the number of enterprises is only partial (around 50%). In order to correct for this, the figures presented here include estimates for unregistered enterprises, together with their related employment and turnover. These estimates for unregistered enterprises are calculated using a combination of: IDBR data; information on persons who are self-employed in their main or second job, taken from the Labour Force Survey carried out by the ONS; and information on the numbers of sole traders and partnerships from the Survey of Personal Incomes data provided by the Inland Revenue.
