As outlined in our blog post Revolutionising administrative data: a look into the future of population and migration statistics, we have published a range of estimates and analysis on the size and structure of the usual resident population of England and Wales in 2021; these estimates include our official population estimates and those produced as part of our research towards transforming our population and migration statistics system.
You can also find updates on how we are transforming international migration statistics.
