POPULATION PRIMER
Population increase or decrease worldwide is a function of two factors: Births and deaths. If births exceed deaths, population increases.
Population increase or decrease within a political unit such as a nation, a state, or a county is a function of four factors: Births and immigration minus deaths and emigration.
If in Country X each birth is matched by one death and each immigrant (a person entering Country X) is matched by one emigrant (a person leaving Country X), the population of Country X will be stable!
However, if the population of Country Y is increasing, births are exceeding deaths and/or immigrants are outnumbering emigrants.
Facts about population growth in the world are not difficult to understand: If births exceed deaths, population grows. Facts about population growth in America are not difficult to understand: If births exceed deaths and/or if immigration exceeds emigration, population grows. Population in the world is growing at an unsustainable rate. Population in the U.S. is growing at an undesirable rate. |
