<p>The information requested falls under the remit of the UK Statistics Authority.</p><p>
</p><p>A response to the noble Lord’s Parliamentary Question of 11 May is below and
attached.</p><p> </p><p>Dear Lord Field,</p><p> </p><p>As National Statistician and
Chief Executive of the UK Statistics Authority, I am responding to your Parliamentary
Question asking what is the value of the lowest earnings decile, as a percentage of
average earnings, of (1) male, and (2) female, workers in each year since 2020 (HL141).</p><p>
</p><p>The Annual Survey of Hours and Earnings (ASHE) [1], carried out in April each
year, is the most comprehensive source of earnings information in the United Kingdom.
ASHE is based on a 1% sample of employee jobs taken from HM Revenue and Customs' Pay
As You Earn (PAYE) records. [2]</p><p> </p><p>Table 1 shows the median gross weekly
earnings for all, male, and female employees in the United Kingdom for 2020 and 2021
(the latest period for which ASHE estimates are available). [3] As with any survey,
estimates from ASHE are subject to a margin of uncertainty. [4]</p><p> </p><p>Yours
sincerely,</p><p> </p><p>Professor Sir Ian Diamond</p><p> </p><p>Table 1: Median gross

Consequently, individuals with more than one job may appear in the sample more than
once.</p><p>(3) These estimates can be found at: <a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/earningsandworkinghours/datasets/allemployeesashetable1"

The coefficient of variation (CV) indicates the quality of an estimate; the smaller
the CV, the higher the quality. The true value is likely to lie within +/- twice the
CV. For example, for an estimate of £200 with a CV of 5%, we would expect the true
population average to be within the range £180 to £220. This is given by £200+/-({2*0.05}*200).

Employee jobs are defined as those held by employees and not the self-employed.</p><p>
