Following the publication of Northern Ireland level population projections, NISRA subsequently produces official sub-national population projections for areas within Northern Ireland. These sub-national projections are based on 2018 mid-year estimates and assumptions regarding future fertility, mortality and migration for areas within Northern Ireland. In keeping with past practice, these local level projections are constrained to the most recent Northern Ireland level population projections. Projections are available for both current and former Local Government Districts, Health and Social Care Trusts and former Education and Library Boards.
