AP HUMAN GEOGRAPHY UNIT 2 · LABEL THE DIAGRAM
Label the Demographic Transition Model

Tap a numbered point, then tap its matching label in the word bank below.

Natural Increase (Birth Rate − Death Rate)
Total Fertility Rate Curve
Zero Population Growth Line
Infant Mortality Rate Curve
The trap on the exam is naming the stage instead of explaining it: Stage 2’s defining event is the death rate falling while birth rate stays high (usually from better food supply, sanitation, and medicine) — that widening gap is what drives the fastest population growth, not the birth rate itself changing.
