Intra-National Migration, Part 1 - EDA

Introduction What do I do here? This post is an exploration of the UK intra-migration data. Those are open source data that can be downloaded from ONS. ONS uses the NHS Patient Register Data Service (PRDS) to find out the changes in patients adresses. Since most people change their address with their doctor soon after moving, these data are considered to provide a good proxy indicator of migration. The migration data is published every year and consist of Origin Local Authority ID, Destination Local Authority ID, sex, age and movement factor field.
