Learn the skill

A count map and a rate map answer different questions. To compare participation when populations differ, divide the number participating by the relevant population. Do not infer individual behavior from a regional rate. All figures are fictional.

Worked example

20 participants among 100 eligible people is 20%; 20 among 200 is 10%. Equal counts need not mean equal rates.

Three equal-area cells contain different numbers of symbolic dots to show uneven settlement. A separate worked calculation gives 600 people in three square kilometers, averaging 200 per square kilometer. Dots are not individual people counts.
