| Question | Answer |
|---|---|
| Total Fertility Rate | Estimate of the average number of children a woman will have during childbearing years (15-49) |
| Zero Population Growth (ZPG) | Birth rates and death rates are equal. No population growth |
| Crude Birth Rate | Number of live births per 1000 people in a population in a year |
| Life Expectancy | The average number of years we can expect to live |
| Infant Mortality Rate | The average number of infants that die per year |
| Age Structure | Distribution of individuals among various age groups in a population |
| Pre-reproductive Ages | 0-14 Years |
| Reproductive Ages | 15-44 Years |
| Post-reproductive Ages | 45+ Years |
| Baby Boom Generation | Generation that makes up nearly half of all adult Americans and dominate demand for goods and decisions regarding election (1945-1964) |

| Optimum Sustainable Population | allow most people to live in comfort and freedom without affecting the ability to sustain future generations. |
| Demographic Transition | occurs when countries become industrialized and birth rates and death rates decline |
| Pre-industrial Stage | harsh living conditions lead to high birth rate to compensate for high death rate. |
| Transitional Stage | food increases, and health cares improves, death rates drop and birth rates remain high. |
| Industrial Stage | industrialization is widespread, birth rate drops and eventually approaches the death rate. |
| Post-industrial Stage | birth rates declines even further equaling the death rate and thus reaching ZPG. |
| Demographic Trap | combination of high fertility and declining mortality in developing countries, resulting in a period of high population growth rate. |
| Crude Death Rate | Number of deaths per 1000 people in a population in a year |
