Monitoring and reporting progress

The expected outputs from the Authority’s long-term ambition to put administrative data at the core of population and migration statistics are: 

1. Population and migration statistics at national and local level, including coherent UK estimates.
2. Statistics on characteristics, housing and living arrangements, improving our understanding of society and communities at national and local levels, including multivariate statistics.
3. Population and household projections including variant projections in response to user needs.
4. Expert insight into structural demographic change and the related demographic challenges facing our society (including ageing, fertility and mortality), building understanding of demography across government.
5. Cross-sectional and longitudinal data assets that allow for research and analysis.
6. Additional indicators and insights providing new or early insights into the population, built from existing and novel data sources.

The Authority will monitor and publicly report on the ONS’s progress in delivering of these recommendations on a periodic basis in the future. The first of these reports should be made in 2026. 

To support this reporting, the Authority proposes to establish a focused subcommittee of the Board, with a remit to advise the Board regularly on progress on the full breadth of the population statistics system. It would include senior leaders from across government and beyond, alongside relevant experts and Authority non-executive directors.
