Data drives decisions
- Geographic data is powerful because it guides real decisions.
- Businesses use it to choose store locations; governments use it to plan.
- Aid agencies use it to send help where it is needed most.
Governments plan with data
- A census 人口普查 counts a population and its characteristics.
- Census data decides where to build schools, hospitals, and roads.
- Without accurate data, public services go to the wrong places.
Who uses this data?
Sort each use of geographic data by who makes the decision.

Select all ways geographic data can save lives.
Rescue, disease mapping, and evacuation planning all save lives; decoration does not.
Data is not neutral. The categories chosen, and how a map is coloured or scaled, can change the message. The same numbers can be drawn to reassure or to alarm — a map can inform or mislead.
Because a map uses real numbers, it is always neutral and cannot mislead.
The categories chosen and the way a map is coloured or scaled can change the message — even with real data.
Data and power
- Whoever controls data has power to shape decisions.
- That is why open, accurate data matters for fairness.
- A careful geographer always asks who made the data and why.
A coffee chain wants a new shop. It overlays census income data, foot-traffic counts, and a map of competitors. The spot with high income, heavy footfall, and few rivals is the winner — a decision made entirely from geographic data.
Geographic data is powerful because it drives decisions — where businesses build, where governments plan, and where aid goes. But data is selective and not neutral: the categories and map design shape the message, so always question the source.
