Census and public data — Civics, 11–13
Why communities count people and collect facts before planning services, resources and representation.
A census makes a community visible
A census is a careful count of people and homes, often with basic information about where and how they live. Other public data can count buses, pupils or hospital visits. Together, these numbers show patterns that individual stories cannot show alone.
Why count before planning?
Without numbers, a decision-maker may guess how many classrooms, buses or clinics are needed. Counts do not tell the whole story, but they provide a shared starting point for planning and for asking whether resources are reaching different parts of the community.
Using a simple count
A town counts 1,200 homes and finds that 240 have no nearby bus stop. Divide 240 by 1,200: 0.2, or 20%. The town now knows the size of the gap, then combines this figure with distance, age and mobility data before choosing a route.
Numbers are not the whole truth
It is tempting to treat a chart as perfectly neutral because numbers look objective. But someone chose what to count, how to define it and which period to show. A low number may mean little need—or that people were missed or could not answer.
Data in everyday public choices
Public data can guide where a new cycle lane goes, how often rubbish is collected or which areas need shade and trees. You can use it as a starting point, then ask residents whether the numbers match what they actually experience.
