The European Standard Population (ESP) is an artificial population structure which is used in the weighting of mortality or incidence data to produce age standardised rates. Eurostat, the statistical institute of the European Union, has decided to bring this population structure up to date.
ONS is consulting on how to implement the change in the UK. This consultation is on behalf of the Government Statistical Service (GSS) as a whole, as there are other government bodies which publish statistics that will be affected. However, it should be noted that because the various government bodies vary in their responsibilities, priorities and resources, and the nature of their statistical publications, they will not necessarily all follow the same approach following this consultation.
