In developed countries, once population has stabilized zero population growth, it corresponds to a fertility rate of about 2.1; that is, each woman has a baby to replace herself and her mate plus a small adjustment for pre-reproductive deaths.
Zero population growth requires that births and immigration equal the sum of deaths and emigration.
Population momentum is often described as the tendency for populations to continue to grow for several generations after zero population growth fertility rates have been achieved.

 Zero Population Growth!
ZPG is a bad excuse for abortion and the birth control pill.
If she had any reason at all, if she understood anything about what she was doing, it was only to get even with men for having 3 1/2 billion more brain cells than her and thus creating things like civilization and a US Constitution which she is utterly incapable of comprehending.
The feminists' support of ZPG is the ultimate example of their total abject stupidity, extreme ignorance, and firm moral minorship.

 Zero Population Growth versus The Free Society   (Site not responding. Last check: 2007-11-02)
McNamara continues, "rampant population growth is an even more dangerous and subtle threat to the world than thermonuclear war, for it is intrinsically less subject to rational safeguards, and less amenable to organized control.
I have cited a tiny bit of the evidence on the other side, merely to cast some doubt on the ZPG thesis that there is a demographic crisis which provides a new rationale for governmental intrusion into affairs once regarded as most private and personal-a couple's decision as to the size of their future family.
And the idea of Zero Population Growth could not possibly make any headway in a society with healthy values, where people experienced a genuine lust for life, appreciated the vast promise in every newborn child, loved life for its joys and took its pains in stride, and experienced life as a venture in destiny.

Other studies have countered with the claim that the current population level of over six billion may be supported by current resources, or that the global population may grow to ten billion and still be within the Earth's carrying capacity.
One of the strongest criticisms of an optimistic outlook is that of the fossil fuel subsidy of modern agriculture.
Some overpopulation activists have taken the position that population growth must be dealt with on a country-by-country basis, and therefore support a reduction in immigration into some countries, including the United States, in order to stabilize their population.

Population growth is a result of the difference between death rate and birth rate (ignoring immigration and emigration for now), so the decreased death rate leads to a high growth rate.
Instead of focusing just on controlling population growth (an approach which was not very effective) this program tries to identify and deal with the many interrelated social problems that contribute to population growth and poverty.

The bureau says that for the population to reach 50 million this century, fertility would need to rise to 3.9 babies per woman or immigration would need to quadruple to 490,000 people a year.
The bureau's projections for the ageing of the population have the greatest implications for social policy.
You may be inclined to regard these population projections as of academic interest, since you won't be around to see if the bureau is correct.

 Checks on Population Growth
As the human population grows, jungles are cleared for agriculture, farms are paved for shopping centers, rivers are dammed for hydroelectric power and irrigation, etc. Although wildlife sanctuaries are being established, they must be made large enough so that they can support populations large enough to survive density-independent checks when they strike.
Because of this lag, one might expect that the lemming population would continue to outstrip the weasel population until the lemmings bumped into the carrying capacity of their environment (e.g., availability of food and nesting sites).
Plotting the growth of a population from an initial growth realization factor of 1 to a final factor of 0 produces a curve like this, called the logistic growth curve or S-shaped curve of growth.

 Population Growth
Human population growth is probably the greatest potential environmental threat to the planet today.
When you look at the future growth predictions, and if you consider simply the core needs for human existence: water, food, housing, energy for cooking and warmth, it is very easy to imagine the potential impact of eight billion people on the planet.
Most of the world's expected human population growth will be in resource-poor countries that today barely support current population levels.

 Exponential Growth and Population
The difference between linear growth (constant number of units growth per year) vs exponential growth (constant percentage increase) is difficult to see initially, if the exponential growth rate is small.
ZPG is only achieved in a model which limits immigration (a very politically sensitive issue), restricts birthrates to no more than 2 per female (more politics), and makes no attempt to increase life expectancy.
Equilibrium is difficult to achieve because exponential growth produces demographics such that they are substantially more people entering their reproductive years than those which are dying of old age.

As I suggested in my post on "market saturation," it is possible that what you see instead of a collapse is that the drop out rate eventually reaches an equilibrium with the rate at which new "distributors" are recruited into the scheme.
Second, the population of the United States in 1970 was approximately 203 million people.
Let's take the 360,000 distributors in 1977 and applied the population growth rates for '77 to '93, which was 32% over that period.

 Zero Population Growth: Keeping Our Perspective
Zero population growth (ZPG) is a long way off in many countries, especially those with a bottom-heavy demographic pyramid (more young people).
In China's case, the war against population growth (it seems like a war, what with all the strategies and the single-mindedness of the attack) has been waged successfully (the fertility rate has definitely dropped), but not, it seems, without its costs.
China is not the only country with a reductionist approach to population control, boiling down this complex matter to the single issue of numbers.

 Map & Graph: Countries by People: Population growth rate
Definition: The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country.
The growth rate is a factor in determining how great a burden would be imposed on a country by the changing needs of its people for infrastructure (e.g., schools, hospitals, housing, roads), resources (e.g., food, water, electricity), and jobs.
Rapid population growth can be seen as threatening by neighboring countries.

ZPG takes place in an over-populated future so polluted that people wear gas masks outside (we eventually find out it is war related), animals are found only in a museum (stuffed), and food is found only in paste form.
In ZPG we are introduced to a couple (Oliver Reed and Geraldine Chaplin) who work and live as a 1971 typical swinging couple exhibit in the museum along with another couple (best friends/neighbors).
When the couple decides to have a baby anyway they are forced to share it with their neighbors or face certain death.
