Home Demographics Population Age Composition

Age Composition

Age is a basic demographic characteristic that intersects other social characteristics such as education, and economic characteristics such as labor force participation. Changes in the age composition of the population can signify future social and economic trends. Between 2000-2022, the number of people 60 years and older has markedly increased in all four counties. With an aging population, community development and planning may need to be reoriented to create appropriate services and infrastructure to suit different age groups.

Note: While the 2000, 2010, and 2020 data are based on decennial census, the 2022 data is based on 5-year estimates (2018-2022). Users should exercise caution when comparing this data.
