Natality and Immigration
|
Explanation:
Detailed explanation-1: -The first is through births of new individuals. The way we measure additions of this type is with the natality rate (also called the birth rate), which is the number of births per 1000 individuals per unit of time, usually per year. The second way individuals are added to the population is through immigration.
Detailed explanation-2: -Population projections show that increased immigration-even to levels of 1 million migrants a year-will not only increase the national growth rate, but also slow the nation’s aging population trajectory and lead to increased numbers of children and younger members of the labor force.
