Improving our Population and Migration Statistics

ONS is committed to continually improving its existing population and migration statistics. These are the statistics that bridge the gap between Censuses. Often this means researching better methods. It also means engaging with users, responding to your needs, and assessing other improvements - for example, timeliness. The Beyond 2011 programme researching longer term alternatives to a traditional Census reports its findings separately, but the two research programmes are linked and collaborate regularly.

You can download our strategy for population statistics 2014-2019 from the download panel on the right hand side of this page, and our population statistics revisions policy which sets out how we will revise our figures if and when research leads to a change in methods (ie how they are produced) for a particular statistic or set of figures.  You will also find a link to minutes and write-ups from the main meetings and user groups that help us develop and prioritise future work on population statistics.

Methodological research since the last Census

Every Census presents an opportunity to review our statistics on the size and characteristics of the population.  As most of our statistics are aimed at bridging the gap between Censuses, research programmes tend to reflect this 10 year cycle.

Migration Statistics Improvement Programme

In the years leading up to the last Census, this programme extensively researched how we could improve our migration statistics.  The programme is now complete and some methods developed are now in use.  This is an archive of the programme's work.
