According to the CIA's
The World Factbook, the country with the highest birth rate is Niger at 6.49 children born per woman and the country with the lowest birth rate is Taiwan, at 1.13 children born per woman. Compared with the 1950s (when the birth rate was 36 per thousand), as of 2011, the world birth rate has declined by 16 per thousand. 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.
Sub-Saharan Africa The region of
Sub-Saharan Africa has the highest birth rate in the world. As of 2016,
Niger,
Mali,
Uganda,
Zambia, and
Burundi have the highest birth rates in the world. This is part of the
fertility-income paradox, as these countries are very poor, and it may seem counter-intuitive for families there to have so many children. The inverse relationship between income and fertility has been termed a
demographic-economic "paradox" by the notion that greater means would enable the production of more offspring as suggested by the influential
Thomas Malthus.
Afghanistan Afghanistan has the 11th highest birth rate in the world, and also the highest birth rate of any non-African country (as of 2016). Reasons for large families include tradition, religion, the different roles of men and women, and the cultural desire to have several sons.
Australia Historically,
Australia has had a relatively low fertility rate, reaching a high of 3.14 births per woman in 1960. This was followed by a decline which continued until the mid-2000, when a one off cash incentive was introduced to reverse the decline. In 2004, the then
Howard government introduced a non-means tested 'Maternity Payment' to parents of every newborn as a substitute to maternity leave. The payment known as the 'Baby Bonus' was A$3000 per child. This rose to A$5000 which was paid in 13 installments. Australia's fertility rate reached a peak of 1.95 children per woman in 2010, a 30-year high, 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. In 1994, the total fertility rate was as low as 1.66, but perhaps due to the active family policy of the government in the mid-1990s, it has increased, and maintained an average of 2.0 from 2008 until 2015. 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 income tax imposition system is known as the family coefficient of income tax. 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. • a medical insurance system that covers all medical expenses, hospitalization costs, and medical expenses incurred after six months of pregnancy as 100% of the national health insurance in the national social security system, and the statutory leave system during pregnancy.
Ireland In 2011, Ireland's birth rate was 16.5 per 1,000 (3.5 percent higher than the next-ranked country in the EU, the UK). This reduced to 10.5 per 1,000 by 2022.
Japan (1920–2010) with projected population (2011–2060). As of 2016,
Japan has the third lowest crude birth rate (i.e. not allowing for the population's age distribution) in the world, with only
Saint Pierre and Miquelon and
Monaco having lower crude birth rates. The Japanese sociologist
Masahiro Yamada coined the term "
parasite singles" for unmarried adults in their late 20s and 30s who continue to live with their parents.
South Korea Since joining the Organization for Economic Cooperation & Development (OECD) in 1996, South Korea's fertility rate has been on the decline. It recorded the lowest fertility rate among OECD countries in 2017, with just 1.1 children per woman being born. Subsequent studies indicate that Korea has broken its own record and that the fertility rate has fallen to below one child per woman. The total fertility rate in South Korea sharply declined from 4.53 in 1970 to 2.06 in 1983, falling below the replacement level of 2.10. The low birth rate accelerated in the 2000s, with the fertility rate dropping to 1.48 in 2000, 1.23 in 2010, and reaching 0.72 in 2023. 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. 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 (
IMF crisis) in 1997; fathers abandoning their families because they could not financially support them.
Taiwan In August 2011, Taiwan's government announced that its birth rate declined in the previous year, despite the fact that the government implemented approaches to encourage fertility.
United Kingdom In July 2011, the UK's
Office for National Statistics (ONS) announced a 2.4 percent increase in live births in the United Kingdom in 2010. This is the highest birth rate in the UK in 40 years.
United States There has been a dramatic decline in birth rates in the U.S. between 2007 and 2020. The Great Recession appears to have contributed to the decline in the early period. A 2022 study did not identify any other economic, policy, or social factor that contributed to the decline. 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). 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. ==Factors affecting birth rate==
