Dear Usoc Team,

I work for HMRC on the evaluation of the Self-Employment Income Support Scheme (SEISS). I’m hoping you can help me with a query I have about the Understanding Society study and supplementary COVID questionnaire.

I’m currently doing some work to understand whether data from external surveys are likely to be suitably robust at the self-employed level for use in our evaluation. I’ve looked through your website and see that it will be necessary to sign up to the UK Data Service before being able to access your data. As my work is fast paced, I’m hoping you will be able to answer a few questions I have in advance of me applying for this accreditation.

• Please can you provide information on the respondent base sizes that you achieved in your most recent wave? (Base for working age adults / for the self-employed / for claimants of SEISS)
• Is the COVID survey data matched back at a respondent level to your main longitudinal survey data?

Apologies if this isn’t a straightforward request. Any help you can provide is extremely appreciated!

Many Thanks,
Josh Munday

1. The best way to find out sample sizes for the main survey is to use the online variable search facility:
(a) In the main survey, the variable JBSTAT asks about the main activity status at the time of interview. If you click here:
you can find the frequency distribution by wave. For the last wave released (wave 10, 2018-19 with a few interviews in early 2020),
the # of self-employed were 2729
(b) As there are different definitions of working age, best would be to look at the frequency distribution of the age variable, AGE_DV:

2. In the Covid survey, use the variable SEMPDERIVED to identify the self-employed, AGE measures age, and the variable SEMPGOVT to identify those who were told by the HMRC that they were eligible for govt support for the self-employed, SEMPGOVT2 to identify those who had received this support (SEMPGOVT3a SEMPGOVT3b about receiving this support in Rounds 2 & 3) The variable search for the Covid survey is here:

3. Yes the Covid data is matched back to the main survey data - both sets of data files include the unique individual ID, PIDP. Using that variable you can match individual records across the two datasets.

Hope this helps. If you need further help or clarifications let us know.

Best wishes,
Understanding Society User Support Team
