The Data City estimates Gross Value Added (GVA) at company and RTIC level. This is available in ANALYSE and EXPLORE. In EXPLORE, you will find GVA information in the financials tab of a company profile. In ANALYSE, you will find GVA data in the analysis summary box. image png Jan 09 2024 11 51 01 5098 AM GVA data in ANALYSE

How is GVA estimated?

We have produced an estimated GVA measure at the company level using official GVA and employment data . This is an estimate of a company’s UK GVA, if they have overseas operations.
  1. The ONS produces GVA for 104 categories that can be matched to SIC codes. Similarly, the Business Register and Employment Survey (BRES) publishes sectoral employee data that can also be related to SIC codes. With this information, we have produced a measure of average GVA contribution per employee per SIC code.
  2. The Data City have employee and SIC information for each company. Our employment data comes from Companies House, but we use profiles data from Lightcast to better estimate how many employees are UK based. It is therefore possible to estimate a GVA value per company by multiplying the company’s UK employee count (sourced from Data City) by the average GVA employee contribution associated with that same company’s SIC.
  3. A company can have multiple SIC codes. Where this is the case, we split employees equally across the SIC codes and multiply each share of employees by the GVA per employee for each SIC code.
Expect GVA per employee values to range from £50,000 to £200,000 in magnitude.

How to use this data?

When using GVA data for an RTIC or a list of companies, we strongly recommend reviewing the RTIC or list. You should check that the largest companies, by employee count, are appropriate for your analysis.
  • For large companies, is this employee count in line with what you would expect for this company - is the employee count accurate?
  • You may also want to consider whether large companies primarily operate in this sector, or whether their UK operations are not focused on this sector. You may want to remove companies that do not have significant UK operations, or if only a small part of their business falls within the selected sector or RTIC.
We try and estimate the UK GVA of companies using data on where employees are located from Lightcast. We have a large coverage for this data, but it’s important to note not all companies have this data point therefore it should be used with caution still. We cannot estimate GVA for a company if we don’t know which sector (SIC) they’re in. There is a small proportion of companies that do not have SICs. Not all companies have GVA data therefore estimated GVA per employee is calculated by dividing the total UK-adjusted GVA (sum of each company’s EstimatedGVA multiplied by their UK employee proportion) by the total UK employees from companies that have GVA data available. These values are presented in the pop-up box.
Σ(EstimatedGVA × UKProportion) /Σ(BestEstimateUKEmployees*) *where companies have EstimatedGVA > 0
You might want to consider the impact that selecting the “exclude all ultimately foreign companies” filter has on the GVA value. Note: this will not remove UK based multinational firms that have large global employment, such as BP.
Note: You should also be aware that our estimate is of GVA per full-time employee. GVA might be overestimated in sectors which are more likely to have part-time employees, for example, in recruiting agencies.
