I think this subject is best approached in this thread because of the essential role of politics in immigration policies. It's been a highly controversal subject for many years by demographers. Be sure and open the web site to really understand the model.

The dynamics of global population growth differ dramatically across the major regions of the world. In the developed countries, the current annual rate of growth is less than 0.3 percent, while in the rest of the world the population is increasing almost six times as fast. These demographic differences, combined with widening economic disparities, are increasing the pressures of migration from the less-developed to the developed world. How the developed countries respond to the growth of immigration pressures will have a major impact on their demographic and economic futures.

Demographers describe the history of population growth in Western Europe in terms of a process of "demographic transition," a model that charts three aspects of population growth. First, the model describes how the separate factors that create growth (primarily births and deaths) interact. Second, it explains patterns of growth in terms of an ordered sequence of changes in death and birth rates. Third, it suggests how migration affects the growth equation. (See the figure in the next column.)

Particularly important is the shift away from a fatalistic view of demographic behavior that sees life's circumstances as a matter of fate to one that sees them as a consequence of free choice. This shift allows individuals to consider how many children to have, what kind of lifestyle to lead, and where to live. Rather than seeking to have many children, parents place more emphasis on having a few well-educated ones, and family sizes decline. Childbearing is sometimes seen as obstacle to self-fulfillment, and significant numbers of couples refrain from having children.
I read a similar article in the early `90s about the effects of taking immigrants from countries where large families are controlled naturally by higher death rates and fertility levels in women. When outside influences remove a certain level of population, the birth rate adjusted back to normal and the country would be facing the same problem. As with Europe after the plague killed almost half of the population, the birth rate adjusted after the plague to compensate for the drop in population.
