Birth rate, also known as natality, is the total number of live childbirth per 1,000 population for a given period divided by the length of the period in years. The number of live births is normally taken from a universal registration system for births; population counts from a census, and estimation through specialized Demographics techniques such as population pyramids. The birth rate (along with mortality rate and human migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population.See "Fertility rates"; Economic Geography Glossary at University of Washington
When the crude death rate is subtracted from the crude birth rate (CBR), the result is the rate of natural increase (RNI). This is equal to the rate of population change (excluding migration).
The total (crude) birth rate (which includes all births)—typically indicated as births per 1,000 population—is distinguished from a set of age-specific rates (the number of births per 1,000 persons, or more usually 1,000 females, in each age group). The first known use of the term "birth rate" in English was in 1856.

The average global birth rate was 17 births per 1,000 total population in 2024. The death rate was 7.9 per 1,000. The RNI was thus 0.91 percent. In 2012, the average global birth rate was 19.611 per 1,000 according to the World Bank and 19.15 births per 1,000 total population according to the CIA, compared to 20.09 per 1,000 total population in 2007.
The 2024 average of 17 births per 1,000 total population equates to approximately 4.3 births per second or about 260 births per minute for the world. On average, two people in the world die every second or about 121 per minute.
There has also been discussion on whether bringing women into the forefront of development initiatives will lead to a decline in birth rates. In some countries, government policies have focused on reducing birth rates by improving women's rights, sexual and reproductive health. Typically, high birth rates are associated with health problems, low life expectancy, low living standards, low social status for women and low educational levels. Demographic transition theory postulates that as a country undergoes economic development and social change its population growth declines, with birth rates serving as an indicator.
At the 1974 World Population Conference in Bucharest, Romania, women's issues gained considerable attention. Family programs were discussed, and 137 countries drafted a World Population Plan of Action. As part of the discussion, many countries accepted modern birth control methods such as the birth control pill and the condom while opposing abortion. Population concerns, as well as the desire to include women in the discourse, were discussed; it was agreed that improvements in women's status and initiatives in defense of reproductive health and freedom, the environment, and sustainable socioeconomic development were needed.
Birth rates ranging from 10 to 20 births per 1,000 are considered low, while rates from 40 to 50 births per 1,000 are considered high. There are problems associated with high birth rates, and there may be problems associated with low birth rates. High birth rates may contribute to malnutrition and starvation, stress government welfare and family programs, and more importantly store up overpopulation for the future, and increase human damage to other species and habitats, and environmental degradation. Additional problems faced by a country with a high birth rate include educating a growing number of children, creating jobs for these children when they enter the workforce, and dealing with the environmental impact of a large population. Low birth rates may stress the government to provide adequate senior welfare systems and stress families who must support the elders themselves. There will be fewer younger able-bodied people who may be needed to support an ageing population, if a high proportion of older people become disabled and unable to care for themselves.
In stark contrast to Ceaușescu's natalist policy was China's one child policy, in effect from 1978 to 2015, which included abuses such as . This policy has also been deemed responsible for the common practice of sex-selective abortion which led to an imbalanced sex ratio in the country. Given strict family size limitations and a preference for sons, girls became unwanted in China because they were considered as depriving the parents of the chance of having a son. With the progress of prenatal sex-determination technologies and induced abortion, the one-child policy gradually turned into a one-son policy.
In many countries, the steady decline in birth rates over the past decades can largely be attributed to the significant gains in women's freedoms, such as tackling forced marriage and child marriage, access to contraception, equal access to education, and increased socioeconomic opportunities. Women of all economic, social, religious and educational persuasions are choosing to have fewer children as they are gaining more control over their own reproductive rights. Apart from more children living into their adult years, women are often more ambitious to take up education and paid work outside the home, and to live their own lives rather than just a life of reproduction and unpaid domestic work. Birth rates have fallen due to the introduction of family planning clinics and other access to contraception.
In Bangladesh, one of the poorest countries in the world, women are less likely to have two children (or more) than they were before 1999, according to Australian demographer Jack Caldwell. Bangladeshi women eagerly took up contraceptives, such as condoms and the pill, according to a study in 1994 by the World Bank. The study proved that family planning could be carried out and accepted practically anywhere. Caldwell also believes that agricultural improvements led to the need for less labour. Children not needed to plough the fields would be of surplus and require some education, so in turn, families become smaller and women are able to work and have greater ambitions. Other examples of non-coercive family planning policies are Ethiopia, Thailand and Indonesia.
Myanmar was controlled until 2011 by an austere military junta, intent on controlling every aspect of people's lives. The generals wanted the country's population doubled. In their view, women's job was to produce babies to power the country's labour force, so family planning was vehemently opposed. The women of Burma opposed this policy, and Peter McDonald of the Australian National University argues that this gave rise to a black market trade in contraceptives, smuggled in from neighbouring Thailand.
In 1990, five years after the Iraq-Iran war ended, Iran saw the fastest recorded fall in fertility in world history. Revolution gave way to consumerism and westernization. With TVs and cars came condoms and birth control pills. A generation of women had been expected to produce soldiers to fight Iraq, but the next generation of women could choose to enjoy some newfound luxuries. During the war, the women of Iran averaged about 8 children each, a ratio the hard-line Islamic President Mahmoud Ahmadinejad wanted to revive. As of 2010, the birth rate of Iran is 1.7 babies per woman. Some observers claim this to be a triumph of Western values of freedom for women against Islamic state.
Islamic clerics are also having less influence over women in other Muslim countries. In the past 30 years Turkey's fertility rate of children per woman has dropped from 4.07 to 2.08. Tunisia has dropped from 4.82 to 2.14 and Morocco from 5.4 to 2.52 children per woman.
Latin America, of predominately Catholic faith, has seen the same trends of falling fertility rates. Brazilian women are having half the children compared to 25 years ago: a rate of 1.7 children per woman. The Vatican now has less influence over women in other hard-line Catholic countries. Mexico, El Salvador, Ecuador, Nicaragua, Colombia, Venezuela and Peru have all seen significant drops in fertility in the same period, all going from over six to less than three children per woman. Forty percent of married Brazilian women are choosing to get sterilised after having children. Some observers claim this to be a triumph of modern Western values of freedom for women against states with Catholic values.
As of 2017, Niger has had 49.443 births per thousand people. Japan has one of the lowest birth rates in the world with 8 per thousand people. While in Japan there are 126 million people and in Niger 21 million, both countries had around 1 million babies born in 2016.
At a time when Australia's unemployment was at a 28-year low of 5.2%, the then Treasurer Peter Costello stated there was opportunity to go lower. With a good economic outlook for Australia, Costello held the view that now was a good time to expand the population, with his famous quote that every family should have three children "one for mum, one for dad and one for the country". Australia's fertility rate reached a peak of 1.95 children per woman in 2010, a 30-year high, although still below replacement rate.
Phil Ruthven of the business information firm IBISWorld believes the spike in fertility was more about timing and less about monetary incentives. Generation X was now aged 25 to 45 years old. With numerous women putting pregnancies off for a few years for the sake of a career, many felt the years closing in and their biological clocks ticking.
On 1 March 2014, the baby bonus was replaced with Family Tax Benefit A. By then the baby bonus had left its legacy on Australia.
In 2016, Australia's fertility rate has only decreased slightly to 1.91 children per woman.
France has embarked on a strong incentive policy based on two key measures to restore the birth rate: family benefits ( les allocations familiales) and a family-coefficient of income tax ( le quotient familial). Since the end of World War II, early family policy in France has been based on a family tradition that requires children to support multi-child family, so that a third child enables a multi-child family to benefit from family allowances and income tax exemptions. This is intended to allow families with three children to enjoy the same living standards as households without children.
In particular, the French income taxation system is structured so that families with children receive tax breaks greater than single adults without children. This income tax imposition system is known as the family coefficient of income tax. A characteristic of the family factor is that households with a large number of children, even if they are at the same standard of living, can receive more tax exemption benefits.
Since the 1970s, the focus has been on supporting families who are vulnerable such as single parent families and the children of a poor family in order to ensure equality of opportunity. In addition, as many women began to participate in the labor market, the government introduced policies of financial support for childcare leave as well as childcare facilities. In 1994, the government expanded the parent education allowance ( l'allocation parentale d'éducation) for women with two children to ensure freedom of choice and reduce formal unemployment in order to promote family well-being and women's labor participation.

One example of Korea's economic crisis is the housing market. Tenants may choose to buy, rent, or use the Jeonse system of renting. Landlords require the renters to upfront as much as 70% of the property value as a type of security deposit, then live rent free for the duration of the contract, usually two years. At the end of the contract, the deposit is refunded 100% back to the renter. Historically, landlords have invested the security deposit and banked on rising property values. But as inflation rises higher than the interest rates, property values plummeted. Recent government caps, aimed at protecting the renters from being victims of price gouging, restricted the profit the landlord can make on renewing the contract.
The Korean government offers a wide range of financial incentives to parents; however, many new parents, both mother and father, refuse to take full advantage of postpartum parental leave. Some fathers fear being ridiculed for taking "mom leave" while both working parents fear the stigma of "falling behind" in their professional careers. The South Korean corporate world is very unsympathetic to family needs.
Abortion and divorce are other contributing factors for Korea's low birth rate. In the twentieth century, due mainly to Confucian beliefs and a strong desire to sire a son, female fetuses were being aborted. This strong desire to have a son as a first child has somewhat of an oxymoron effect on today's low birth rate, as many women will not want to marry the oldest son, aware of his financial obligation to feed, clothe and shelter the aging parents. As a result, in 1988 the government banned doctors from telling expectant parents the sex of the fetus. Effective 1 January 2021, abortion has been decriminalized. Divorce is another deterrent to childbirth. Although divorce has been on the rise over the last 50 years, it hit families especially hard after the economic crisis in 1997; fathers abandoning their families because they could not financially support them. In addition, the abortion of female fetuses lead to a relative shortage of women, resulting in overall lowerall birthrate in the country.
A Pew research center study found evidence of a correlation between economic difficulties and fertility decline by race and ethnicity. Hispanics (particularly affected by the recession) have experienced the largest fertility decline, particularly compared to Caucasians. In 2008–2009 the birth rate declined 5.9 percent for Hispanic women, 2.4 percent for African American women and 1.6 percent for white women. The relatively large birth rate declines among Hispanics mirror their relatively large economic declines, in terms of jobs and wealth. According to the statistics using the data from National Centre for Health Statistics and U.S. Census Bureau, from 2007 to 2008, the employment rate among Hispanics declined by 1.6 percentage points, compared with declines of 0.7 points for whites. The unemployment rate shows a similar pattern—unemployment among Hispanics increased 2.0 percentage points from 2007 to 2008, while for whites the increase was 0.9 percentage points. A recent report from the Pew Hispanic Center revealed that Hispanics have also been the biggest losers in terms of wealth since the beginning of the recession, with Hispanic households losing 66% of their median wealth from 2005 to 2009. In comparison, black households lost 53% of their median wealth and white households lost only 16%.
Other factors (such as women's labor-force participation, contraceptive technology and public policy) make it difficult to determine how much economic change affects fertility. Research suggests that much of the fertility decline during an economic downturn is a postponement of childbearing, not a decision to have fewer (or no) children; people plan to "catch up" to their plans of bearing children when economic conditions improve. Younger women are more likely than older women to postpone pregnancy due to economic factors, since they have more years of fertility remaining.
In July 2011, the U.S. National Institutes of Health announced that the adolescent birth rate continues to decline. In 2013, teenage birth rates in the U.S. were at the lowest level in U.S. history. Teen birth rates in the U.S. have decreased from 1991 through 2012 (except for an increase from 2005 to 2007). The other aberration from this otherwise-steady decline in teen birth rates is the six percent decrease in birth rates for 15- to 19-year-olds between 2008 and 2009. Despite the decrease, U.S. teen birth rates remain higher than those in other developed nations. Racial differences affect teen birth and pregnancy rates: American Indian/Alaska Native, Hispanic, and non-Hispanic black teen pregnancy rates are more than double the non-Hispanic white teenage birth rate.
States strict in enforcing child support have up to 20 percent fewer unmarried births than states that are lax about getting unmarried dads to pay, the researchers found. Moreover, according to the results, if all 50 states in the United States had done at least as well in their enforcement efforts as the state ranked fifth from the top, that would have led to a 20 percent reduction in out-of-wedlock births.
The United States population growth is at a historical low level, mainly because the United States birth rates in the 2010s and 2020s are the lowest ever recorded. The low birth rates in the United States post-2010 can possibly be ascribed to the recession that started in 2008, which led families to postpone having children and fewer immigrants coming to the US. The US birth rates in 2010-2014 were not high enough to maintain the size of the U.S. population, according to The Economist. Since that period, the birth rate (births per 1,000 inhabitants) has further declined from roughly 12 to roughly 10.
Reproductive health can also affect the birth rate, as untreated infections can lead to fertility problems, as can be seen in the "infertility belt" - a region that stretches across central Africa from the United Republic of Tanzania in the east to Gabon in the west, and which has a lower fertility than other African regions.
Child custody laws, affecting fathers' parental rights over their children from birth until child custody ends at age 18, may have an effect on the birth rate. U.S. states strict in enforcing child support have up to 20 percent fewer unmarried births than states that are lax about getting unmarried fathers to pay, the researchers found. Moreover, according to the results, if all 50 states in the United States had done at least as well in their enforcement efforts as the state ranked fifth from the top, that would have led to a 20 percent reduction in out-of-wedlock births.
Some scholars believe there exists a form of "cultural selection" that will significantly affect future demographics due to significant differences in birth rates between cultures, such as within certain religious groups, that cannot be explained by factors such as income. In the book Shall the Religious Inherit the Earth?, Eric Kaufmann argues that demographic trends point to religious fundamentalists greatly increasing as a share of the population over the next century. From the perspective of evolutionary psychology, it is expected that selection pressure should occur for whatever psychological or cultural traits maximize fertility. Can we be sure the world's population will stop rising?, BBC News, 13 October 2012
