What does it mean to have zero population growth?
Zero population growth, sometimes abbreviated ZPG (also called the replacement level of fertility), is a condition of demographic balance where the number of people in a specified population neither grows nor declines, considered as a social aim by some.
Is it bad to have zero population growth?
People create and innovate, designing technologies and systems that have increased overall quality of life since 1968, even as the global population doubled. Other critics of zero population growth believe that low birth rates are bad for the economy.

When does zero population growth occur? Do no births or deaths occur? It occurs when the per capita birth and death rates are equal.
What does zero population growth mean and where is this occurring?
Zero Population Growth (ZPG) occurs when the number of people who die and emigrate out of a country equals the number of people who are born or immigrate into a country. This means that there is no net change, which means that the number of people born equals the number of people who have died.

What was the ZPG movement?
In the late 1960s ZPG became a prominent political movement in the U.S. and parts of Europe, with strong links to environmentalism and feminism. Yale University was a stronghold of the ZPG activists who believed "that a constantly increasing population is responsible for many of our problems: pollution, violence, loss of values and of individual privacy." Founding fathers of the movement were Paul Ehrlich, author of The Population Bomb, Richard Bowers, a Connecticut lawyer, and Professor Charles Lee Remington. Ehrlich stated: "The mother of the year should be a sterilized woman with two adopted children."

What happens when fertility is below replacement?
Conversely, with fertility below replacement, a large elderly generation eventually results (as in an aging " baby boom "); but since that generation failed to replace itself during its fertile years, a subsequent "population bust", or decrease in population, will occur when the older generation dies off. This effect has been termed birth dearth. In addition, if a country's fertility is at replacement level, and has been that way for at least several decades (to stabilize its age distribution), then that country's population could still experience coincident growth due to continuously increasing life expectancy, even though the population growth is likely to be smaller than it would be from natural population increase.
Why is it so hard to achieve ZPG?
Achieving ZPG is difficult because a country's population growth is often determined by economic factors, incidence of poverty, natural disasters, disease, etc. However, even if there is zero population growth, there may be changes in demographics of great importance to economic factors, such as changes in age distribution .
What is the effect of population growth on the long term?
Effects. In the long term, zero population growth can be achieved when the birth rate of a population equals the death rate, i.e. fertility is at replacement level and birth and death rates are stable, a condition also called demographic equilibrium. Unstable rates can lead to drastic changes in population levels.

How much will the world population grow in 2050?
If the current world value for r (1.2%) remains unchanged, the world population would grow from its current 6.9 billion to 9.5 billion over the next 40 years (2050).
How many people will be on Earth in 2050?
The United Nations projects that world population will stabilize at 9.1 billion in 2050. This prediction assumes a decline from the current average global fertility rate of 2.56 children per woman to 2.02 children per woman in the years between 2045 and 2050. But should mothers average half a child more in 2045, the world population will peak at 10.5 billion five years later. Half a child less, and it stabilizes at 8 billion. The difference in those projections—2.5 billion—is the total number of people alive on Earth in 1950.
How can we stop ecological overshoot?
The only known solution to ecological overshoot is to decelerate our population growth faster than it's decelerating now and eventually reverse it —at the same time we slow and eventually reverse the rate at which we consume the planet's resources. Success in these twin endeavors will crack our most pressing global issues: climate change, food scarcity, water supplies, immigration, health care, biodiversity loss, even war. On one front, we've already made unprecedented strides, reducing global fertility from an average 4.92 children per woman in 1950 to 2.56 today—an accomplishment of trial and sometimes brutally coercive error, but also a result of one woman at a time making her individual choices. The speed of this childbearing revolution, swimming hard against biological programming, rates as perhaps our greatest collective feat to date.
When will the world reach replacement fertility?
The projection of future TFRs in the upper graph (from the Population Reference Bureau) predicts that the less developed countries of the world will reach replacement fertility around the year 2020. In fact, they will probably reach it sooner because by 2010 the world TFR has dropped to 2.5.
Can we protect the environment without advancing human rights?
The truth, as both camps are coming to realize ,The truth, as both camps are coming to realize, is that you can't protect the environment without advancing human rights— and vice versa. To wit: Every tiny improvement in the status of women, every bit of education for girls, translates into women having more control over their fertility, which translates into family sizes that match parents' means and wishes, which in turn means more opportunity for the next generation—a virtuous cycle of enormous potential.
What Does Negative Natural Population Growth Mean?
This negative or zero natural population growth means that these countries have more deaths than births or an even number of deaths and births; this figure does not include the effects of immigration or emigration. Even including immigration over emigration, only one of the 20 countries ( Austria) was expected to grow between 2006 and 2050, though the rush of emigration from wars in the Middle East (especially Syria's civil war) and Africa in the mid-2010s could revise those expectations.
How much population will Russia lose in 2050?
Russia and Belarus followed close behind at a 0.6 percent natural decrease, and Russia was expected to lose 22 percent of its population by 2050, which would be a loss of more than 30 million people (from 142.3 million in 2006 to 110.3 million in 2050).
Who is Matt Rosenberg?
Matt Rosenberg is an award-winning geographer and the author of "The Handy Geography Answer Book" and "The Geography Bee Complete Preparation Handbook.". Data from the Population Reference Bureau showed in 2006 that there were 20 countries in the world with negative or zero natural population growth expected between 2006 and 2050.
Is Japan a non-European country?
Japan was the only non-European country in the list, though China joined it after the list was released and had a lower-than-replacement birthrate in the mid-2010s. Japan has a 0 percent natural birth increase and was expected to lose 21 percent of its population between 2006 and 2050 (shrinking from 127.8 million to a mere 100.6 million in 2050).
Overview
Zero population growth, sometimes abbreviated ZPG, is a condition of demographic balance where the number of people in a specified population neither grows nor declines, that is, the number of births plus in-migrants equals the number of deaths plus out-migrants. ZPG has been a prominent political movement since the 1960’s. As part of the concept of optimum population, the movement considers zero population growth to be an objective towards which countries and the whole wor…
Definition
The growth rate of a population in a given year equals the number of births minus the number of deaths plus immigration minus emigration expressed as a percentage of the population at the beginning of the given year.
For example, suppose a country begins a year with one million people and during the year experiences one hundred thousand births, eighty thousand deaths, one thousand immigrants an…
History
The American sociologist and demographer Kingsley Davis is credited with coining the term but it was used earlier by George J. Stolnitz, who stated that the concept of a stationary population dated back to 1693. A mathematical description was given by James Mirrlees.
In the late 1960s, ZPG became a prominent political movement in the U.S. and parts of Europe, with strong links to environmentalism and feminism. Yale University was a stronghold of the ZPG …
Effects
In the long term, zero population growth can be achieved when the birth rate of a population equals the death rate, that is, the total fertility rate is at replacement level and birth and death rates are stable, a condition also called demographic equilibrium. Unstable rates can lead to drastic changes in population levels. This analysis is valid for the planet as a whole (assuming that interplanetary travel remains at zero or negligible levels), but not necessarily for a region or coun…
Reaching zero population growth
Albert Bartlett, who was a professor of physics at the University of Colorado at Boulder, suggested that a population has the following choices to achieve ZPG:
1. Voluntarily limit births and immigration to achieve zero population growth;
2. Continue on the present path until the population is so large that draconian measures become necessary to stop the growth of population;
In China
China is the largest country by population in the world, having some 1.4 billion people (as of 2021). China is expected to have a zero population growth rate by 2031.
China's population growth has slowed since the beginning of this century. This has been mostly the result of China's economic growth and increasing living standards. However, many demographers also credit China's family planning policy, formulated in the early 1970s, that enco…
