Providing faster and better estimates of the population

22 November 2021

The pandemic has highlighted the need for more frequent data about our population to understand the biggest challenges facing society. The ONS has been making great strides bringing together new sources of information to build the richest picture possible. Pete Benton explains the improvements we have made, limitations in the estimates, and our ambitions to refine the work in 2022. 

This week we will be updating our population estimates by country of birth data – taking us to mid-year 2021 - while also using new statistical modelling techniques to help better understand patterns of migration in 2020. We’ll be sharing how we’ve used modelling of administrative data for producing migration statistics, which fed into our population estimates and sharing provisional insights with you.  On Friday we will also be updating our research on the development of our admin-based population estimates, including our first time series, and how the student population of England and Wales appears in administrative data. Look out for our next bulletin on Thursday!
