General description

This dataset provides data on the structure of enterprises active in Wales by industry (SIC 2003) 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.

Data collection and calculation

Data are a count of enterprises that are active in the given area within Wales. Enterprises active in more than one area will be counted more than once so the sum across all the areas will not equal the figure for Wales.
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.

2003 to 2009

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.
A fuller description of the methodology used can be found in the document in the main Business Structure folder in this area of StatsWales.
It is important to note that because the analysis is based on this concept of enterprises active in an area that the enterprise counts for sub-areas of Wales will not add up to the Wales totals across these areas. This is because an individual enterprise active in Wales may be active in more than one of the sub-areas of Wales, in which case it will be counted more than once when adding over the areas. However, the employment and turnover variables are fully allocated across the sub-areas of Wales and so addition of these variables over the areas does yield totals that are consistent with the Wales figures.
Estimates for turnover exclude figures for the financial and business services sector throughout this dataset. This is because the turnover information that is recorded on the IDBR for enterprises in the financial services sector also includes the amounts involved in the transactions carried out by these enterprises and is therefore not comparable to turnover information in the other sectors.
