If all women lived to the end of their childbearing years
If all women gave birth according to the rate at each age
Current replacement rate is ___ children per woman

Shows how heavily populated an area is
Found by dividing total _________________ in an area by the total __________________ they occupy

Population density can change over time
Can be misleading due to uneven distribution

19. Carrying Capacity The number of people a piece of land can support
Increased due to:

Abundant Resources
Technology
Wealth
_________________ occurs when the given resources of a piece of land can not support the number of people living on it
