Information
The files starting with mig contain migration data and the ones starting with ttw contain commuting data. The Census year that the data relates to is also indicated in the file name - mostly it's 2021 but for the ttw data (travel to work) I also added in the 2011 file. 

A few of the files are zipped due to them being big. I mainly use geopackage but I did add a shapefile for the ttw-2021 data.

You can find the raw data here: https://www.nomisweb.co.uk/sources/census_2021_od

I also added this file: ODM-2021-22-ALL-journeys-slim.gpkg and it is a GeoPackage GIS-compatible file of the Office of Rail and Road's Origin and destination matrix (ODM) 2021-22 file. What is this? It's an 'origin and destination matrix (ODM) - journeys between all pairs of mainline stations in Great Britain in financial year 2021-22' as described on the ORR website. It's open data (OGL3) but they do not allow users to download the data directly without registration, sadly.
