The Age Structure of the population is the most widely used component of the Census. It is an indicator of an area’s residential role and function and how it is likely to change in the future. Onepoto's age demographics are indicative of the area’s era of settlement and provide key insights into the level of demand for services and facilities (as most services and facilities are age-specific).
