Berkshire Observatory – Slough – Population & Demographics

It is essential to understand population size and characteristics in order to effectively plan and deliver services such as education, transport and healthcare. This section displays the latest population estimates and projections for Slough.

Population estimates are produced using a variety of data sources and statistical models, including some statistical disclosure control methods, and small estimates should not be taken to refer to particular individuals. The estimated resident population of an area includes all those people who usually live there, regardless of nationality. Arriving international migrants are included in the usually resident population if they remain in the UK for at least a year. Emigrants are excluded if they remain outside the UK for at least a year. Armed forces stationed outside of the UK are excluded. Students are taken to be usually resident at their term time address.

The projections below take population estimates as their starting point. The projected local authority populations for each year are calculated by ageing on the population from the previous year, applying local fertility and mortality rates to calculate the number of projected births and deaths, and then adjusting for migration into and out of each local authority. Fertility, mortality and migration assumptions are derived using values estimated using data from the five years before the base projection year, and do not take into account any known policy or demographic changes.
