Population

Service age groups

About this topic

Service age groups divide the population into broad life-stage bands such as children, young adults, working-age adults, and older people. The groupings are designed to reflect typical demand for age-based services and facilities rather than exact five-year cohorts.

This view is useful for planning childcare, schools, recreation, aged services, and other community infrastructure. It works best alongside five year age groups, household type, and dwelling data, which add more detail about who is living in an area and how needs may change over time.

Interpretation notes

  • This is a derived grouping rather than a direct Census question, so the age bands are planning-oriented summaries built from standard age data.
  • Percentages relate to the total population; use five year age groups when exact cohort detail matters.
