“Population projections provide an indication of the future size and age structure of the population based on mid-year population estimates and a set of assumptions of future fertility, mortality and migration. Available for the UK and its constituent countries as national population projections and for the regions, local authorities and clinical commissioning groups in England as sub-national population projections. These projections are widely used for resource allocation and planning”.

A population pyramid, also called an “age-sex pyramid“, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. This tool can be used to visualise the age of a particular population. The following pyramids can be used to compare two different areas and illustrate how those population have changed over the period of the Projections.
