How can I access data on what companies do where?

Where can I find profiles data? How does the Data City split employees/turnover across locations? How do you estimate the employee counts by occupation?

Companies can have multiple locations and companies are not required to provide information on what they do at each location, or how big these locations are.

The Data City have integrated data from Lightcast to better answer the question of what companies do where. Specifically, we use Lightcast profiles data to understand the occupations and locations of employees for companies. We sometimes refer to this as WhatWhere data.

You'll find this data in analyse and explore.

Explore

On explore, you'll find WhatWhere data on the locations tab of a company, where we have it.

Not all companies have WhatWhere data, but a significant proportion of large companies do.

The counts listed below are the number of Lightcast profiles in each location and occupation.

Analyse

On analyse, we've integrated profiles data in many places. Currently, we treat profiles data differently than on explore.

Where explore is the raw count of profiles, on analyse we've combined companies' declared employees with the percentage of profiles in a location or occupation.

This is done as a company's employee count can be different than the number of profiles we have for it, and the declared employee count is our preferred source.

Page Location Field Detail
Analyse Summary Box Total UK Employees We use profiles data to better understand how many employees are based in the UK vs the Rest of the World.
Analyse Summary Box Best Estimate Total GVA We use profiles data to focus our GVA estimate on UK activity. This is done by using the percentage of UK employees, of total employees.
Locations Employees by geography

For each of the geographies (Local Authority, Strategic Authority, etc.) we use profiles data where available. 

This allows us to better represent firms' activity across the country. 

Where we do not have profiles data, we fall back to splitting a company's employees equally across the number of locations it has.

 

Locations Turnover by geography

We do not apply profiles data to inform turnover by geography.

Turnover by geography is the result of splitting a company's total turnover across the number of sites it has.

Jobs and Skills Occupation counts

We use profiles data, to estimate the number of employees by occupation.

This draws upon Lightcast's extensive occupational taxonomy. Thousands of individual occupations are aggregated to form the categories presented.
