The National Records of Scotland (formerly GROS) provides access to estimates of migration within Scotland, between Scotland and the rest of the UK and between Scotland and overseas. As there is currently no comprehensive registration of migration within, to and from the UK, these statistics are derived from survey data and the best existing proxy data. There is accompanying information on the methodology employed in their production.
