Compare population rates fairly practice
Normalize invented population counts and distinguish relative change from raw totals.
Opening your practice adventure…
Try a sample
Two towns report the same total births, but one has twice the population. Which has the lower births-per-resident rate?
- Both must have the same rate.
- The smaller town.
- Population size cannot affect a per-resident rate.
- The town with twice the population.
See the answer & why
The town with twice the population.
The same numerator divided by a larger population gives a lower rate.
A little hint: Use the stated denominator and time period; raw counts and rates answer different questions.
