Why do population trends matter? Because the starting point for any school funding calculation is the number of pupils at a school. A local authority with a falling population will find itself dealing with surplus places. One with an increasing population will need to look at increasing provision.
The map shows the level of occupancy in schools—that is the number of actual pupils as a percentage of the number of pupils a school can admit.
