Population and demographics data is an important tool in helping to understand a local area, the needs of the people that live there and how these change over time. As part of this information, population projections help local authorities to understand how changes in population will have an impact on future demand and how services can be delivered and designed to manage this.

Guide to Population Projections has been produced to provide more detail about the different projection models that are available, their methodologies and how they are calculated.
