Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what information his Department holds on (a) how many people earn less than £38,700 a year in (i) Wales, (ii) England, (iii) Scotland and (iv) Northern Ireland and (b) what proportion of people earn less than that sum in each constituency in Wales.

HMRC does not publish this information.

Statistics on employment income are published annually as part of the Survey of Personal Incomes. Outturn data for the tax year 2020 to 2021 is the latest available.

Specifically, Table 3.15 contains the latest constituency-level breakdown of taxpayer numbers. This covers individuals with employment income by Parliamentary Constituency. Breakdowns by country and region are also available in this table.
