Access to services varies – several factors affect this.

Describing Distributions

Pattern - ReasonMotorway service stations have a regular and linear pattern …… so that their customers can stop at regular intervals along the motorway for fuel or a rest.

High-street banks are clustered in the centre of town … … because they attract their customers from a large catchment area so they need a prominent location in the centre of town.

Primary schools are distributed quite regularly throughout a large town …… so that every young child has a primary school that is easily accessible from their home.
