Standard Populations

There are two methods of standardising: direct and indirect.

Both methods rely upon reference to a single standard population, which has a known population structure (in the case of direct standardisation) or known age-specific rates (in the case of indirect standardisation). The choice of standard population is important, as it influences the standardised rates or ratios obtained.

Continuity of data The European Standard Population (ESP) was originally introduced in 1976. The statistical institute of the European Union, Eurostat has recognised that there was a need to bring this population structure up to date in order to reflect changes in population. Following discussion with member states, a new ESP (ESP2013) has been created which is based on an average of states' population projections for 2011 - 2030. Statistics providers across the UK, including ISD, will start to use ESP2013 from January 2014.
