what is population momentum?

Answer 1

Here is an easy explanation.
There is no need to go on the internet.

It is the tendency for population growth to continue beyond the time that replacement-level fertility has been achieved because of the relatively high concentration of people in the childbearing years.

Another definition is:

When a population achieves replacement fertility, that population continues to grow for several generations before stabilizing.

Answer 4

People have been aware of the problem of overpopulation for a long time and programs were put in place more than fifty years ago to address the problem. The fertility rate in most of the world is below or is nearing zero population growth levels and the population is increasing mostly because of longer life expectancy. The world population is expected to decline after 2050 when the current young people begin to die in large numbers. There is no reason to think the world will run out of resources before this happens. Only Africa sill has a major population growth problem which is why so much attention is focused on them . We are already in a bidding war for oil because it is traded on world markets. However we use far more per person than other industrialize nations and we can reduce our consumption by half if we used it as efficiently as other countries do without a major loss in our standard of living.

Answer 6

Remember, too, that populations tend to grow exponentially where the average birth rate is larger than the replacement rate (i.e. where 2 parents have more than 2 children that live to bear children). Where the birth rate is lower than the replacement rate, the population tends to shrink exponentially. So it will either increase at an increasing rate or decrease at an increasing rate.

For further references, see Wikipedia's "Population" and "Thomas Malthus" entries. Malthus' work indicated that where a population increases too rapidly, it outgrows its resources and causes shortages of food, water, etc.
