According to the concept of the "demographic transition," a population will go through a period of expansion, but later stabilize at:
at a population larger than before the transition, but with zero growth
Based on the history of human populations in various countries, what might be expected to change as per-capita income increased?
average family size decrease
The crude growth rate is defined as:
birth rate minus death rate
The demographic transition defines
both a decline in population growth over time and a pattern of change in birth and death rates that occur as the result of industrial and economic development
If a population has a pyramid-shaped age structure (many youth tapering to few elderly), it
both illustrates a rapidly growing population and indicates the need for more jobs in the future

exponential
capacity to become pregnant
fertility
In the history of human population growth, the rapid expansion experienced during the Industrial Revolution can, in part, be attributed to
