How census data is used
Census data informs decisions that affect everyday life, including:
- planning public services (such as schools, hospitals, and transport)
- allocating funding (making sure resources are distributed fairly across communities)
- policy development (supporting evidence-based decisions in government and local councils)
- academic research (providing rich data for studies in health, housing, employment, and more)
- business and investment (helping organisations understand population trends and local needs)
