National population projections (NPPs) migration assumptions methodology review

In 2012 we commissioned the Economic and Social Research Council Centre for Population Change to carry out a review of the methodology used in setting migration assumptions for the NPPs and to make recommendations for future methods.

As a result, the methodology for setting the migration assumptions for the 2012-based NPPs has been revised to incorporate findings from the review.
