| 60. Migration transition | change in the migration pattern in a society that results from industrialization, population growth, and other social and economic changes that also produce the demographic transition. |
| 35. Demographic momentum | (population momentum) the tendency for population growth to continue despite stringent family planning programs because of a relatively high concentration of people in the childbearing years. |
