As a country moves from a subsistence economy to industrialization and increased affluence, it undergoes a predictable shift in population growth.

39. 4 Phases
Name the four phases

40. 4 Phases
Slow Population Growth: population nearly in a steady state.
Countries that have not modernized.
2. Rapid Population Growth: Death rate declines as birth rate increases.
3. Stable Population Growth: Birth and death rates decrease.
4. Declining Population Growth: fewer young, more old.
