Since the end of March 2020, the APS has been conducted through telephone interviews instead of face-to-face interviews as a result of the COVID-19 pandemic. The ONS has been monitoring the impact this change has had on the survey and as a result have re-weighted the estimates accordingly. More information about the reasons and methodology can be found on the ONS website (link).The Office for National Statistics has now reweighted the Survey data to new populations derived using growth rates from HM Revenue and Customs (HMRC) Real Time Information (RTI) for January to December 2020 (i.e. quarters 1, 2, 3 and 4 of 2020) to adjust the estimates as a result of these changes. The new estimates about the ability of the population aged three or over to speak Welsh are very similar to the original estimates, varying by between 0 and 0.2 percentage points (or between -600 and 4,800) from the original estimates, at a Wales level. This varies at a local authority level and for the other Welsh language skills (including frequency of speaking Welsh).
