| Migration is one of the most talked about issues in the UK todayâand at the ONS, our job is to measure it. In our next Bringing Data to Life webinar, taking place on Tuesday 22 July from 4pm to 5pm, weâll take you behind the numbers to show exactly how we estimate international migration, what the latest data are telling us, and why the figures sometimes change.  From administrative data to revised estimates, this is your chance to hear directly from the statisticians turning complex global movement into robust and reliable evidence. |
