Question to the HM Treasury:
To ask Mr Chancellor of the Exchequer, how many people are registered as Class 4 national insurance contribution payers by (a) parliamentary constituency and (b) region.
The information requested is attached.
This is based on the Survey of Personal Incomes 2014-15. Constituency numbers are rounded to the nearest 100, and regional numbers to the nearest 1,000. Due to rounding the sum of numbers for Parliamentary constituencies may be different to regional numbers.
