Today, globally, women of childbearing age have an average of approximately 2.2 children over the course of their lifetime. In pre-industrial times, most women could expect to have somewhere between five and ten live births throughout their lifetime; however, the demographic transition then sees fertility rates fall significantly. Looking ahead, it is believed that the global fertility rate will fall below replacement level in the 2050s, which will eventually lead to population decline when life expectancy plateaus. Recent decades Between the 1950s and 1970s, the global fertility rate was roughly five children per woman - this was partly due to the post-WWII baby boom in many countries, on top of already-high rates in less-developed countries. The drop around 1960 can be attributed to China's "Great Leap Forward", where famine and disease in the world's most populous country saw the global fertility rate drop by roughly 0.5 children per woman. Between the 1970s and today, fertility rates fell consistently, although the rate of decline noticeably slowed as the baby boomer generation then began having their own children. Replacement level fertility Replacement level fertility, i.e. the number of children born per woman that a population needs for long-term stability, is approximately 2.1 children per woman. Populations may continue to grow naturally despite below-replacement level fertility, due to reduced mortality and increased life expectancy, however, these will plateau with time and then population decline will occur. It is believed that the global fertility rate will drop below replacement level in the mid-2050s, although improvements in healthcare and living standards will see population growth continue into the 2080s when the global population will then start falling.

The total fertility rate of the world has dropped from around 5 children per woman in 1950, to 2.2 children per woman in 2025, which means that women today are having fewer than half the number of children that women did 75 years ago. Replacement level fertility This change has come as a result of the global demographic transition, and is influenced by factors such as the significant reduction in infant and child mortality, reduced number of child marriages, increased educational and vocational opportunities for women, and the increased efficacy and availability of contraception. While this change has become synonymous with societal progress, it does have wide-reaching demographic impact - if the global average falls below replacement level (roughly 2.1 children per woman), as is expected to happen in the 2050s, then this will lead to long-term population decline on a global scale. Regional variations When broken down by continent, Africa is the only region with a fertility rate above the global average, and, alongside Oceania, it is the only region with a fertility rate above replacement level. Until the 1980s, the average woman in Africa could expect to have 6-7 children over the course of their lifetime, and there are still several countries in Africa where women can still expect to have 5 or more children in 2025. Historically, Europe has had the lowest fertility rates in the world over the past century, falling below replacement level in 1975. Europe's population has grown through a combination of migration and increasing life expectancy, however even high immigration rates could not prevent its population from going into decline in 2021.

In 2025, there are six countries, all in Sub-Saharan Africa, where the average woman of childbearing age can expect to have between 5-6 children throughout their lifetime. In fact, of the 20 countries in the world with the highest fertility rates, Afghanistan and Yemen are the only countries not found in Sub-Saharan Africa. High fertility rates in Africa With a fertility rate of almost six children per woman, Chad is the country with the highest fertility rate in the world. Population growth in Chad is among the highest in the world. Lack of healthcare access, as well as food instability, political instability, and climate change, are all exacerbating conditions that keep Chad's infant mortality rates high, which is generally the driver behind high fertility rates. This situation is common across much of the continent, and, although there has been considerable progress in recent decades, development in Sub-Saharan Africa is not moving as quickly as it did in other regions. Demographic transition While these countries have the highest fertility rates in the world, their rates are all on a generally downward trajectory due to a phenomenon known as the demographic transition. The third stage (of five) of this transition sees birth rates drop in response to decreased infant and child mortality, as families no longer feel the need to compensate for lost children. Eventually, fertility rates fall below replacement level (approximately 2.1 children per woman), which eventually leads to natural population decline once life expectancy plateaus. In some of the most developed countries today, low fertility rates are creating severe econoic and societal challenges as workforces are shrinking while aging populations are placin a greater burden on both public and personal resources.

Following a spike to 2.5 children per woman in the mid-1960s (during the second wave of the post-WWII baby boom), Germany's fertility rate then fell sharply to around 1.5 children per woman in the 1970s, and it has fluctuated between 1.2 and 1.6 children per woman ever since. Germany's fertility rate has been below the natural replacement level of roughly 2.1 children per woman since 1970, meaning that long-term natural population growth is unsustainable. In fact, Germany has experienced a natural population decline in every year since 1972, and its population has only grown or been sustained at its current level through high net immigration rates.Find more statistics on other topics about Germany with key insights such as crude birth rate, life expectancy of women at birth, and total life expectancy at birth.

This map shows the average number of children born to a woman during her lifetime. Data from Population Reference Bureau's 2017 World Population Data Sheet. The world's total fertility rate reported in 2017 was 2.5 as a whole. Replacement-Level fertility is widely recognized as 2.0 children per woman, so as to "replace" each parent in the next generation. Countries depicted in pink have a total fertility rate below replacement level whereas countries depicted in teal have a total fertility rate above replacement level. In countries with very high child mortality rates, a replacement level of 2.1 could be used, since not every child will survive into their reproductive years. Determinants of Total Fertility Rate include: women's education levels and opportunities, marriage rates among women of childbearing age (generally defined as 15-49), contraceptive usage and method mix/effectiveness, infant & child mortality rates, share of population living in urban areas, the importance of children as part of the labor force (or cost/penalty to women's labor force options that having children poses), and religious and cultural norms, among many other factors. This map was made using the Global Population and Maternal Health Indicators layer.

While the standard image of the nuclear family with two parents and 2.5 children has persisted in the American imagination, the number of births in the U.S. has steadily been decreasing since 1990, with about 3.6 million babies born in 2023. In 1990, this figure was 4.16 million. Birth and replacement rates A country’s birth rate is defined as the number of live births per 1,000 inhabitants, and it is this particularly important number that has been decreasing over the past few decades. The declining birth rate is not solely an American problem, with EU member states showing comparable rates to the U.S. Additionally, each country has what is called a “replacement rate.” The replacement rate is the rate of fertility needed to keep a population stable when compared with the death rate. In the U.S., the fertility rate needed to keep the population stable is around 2.1 children per woman, but this figure was at 1.67 in 2022. Falling birth rates Currently, there is much discussion as to what exactly is causing the birth rate to decrease in the United States. There seem to be several factors in play, including longer life expectancies, financial concerns (such as the economic crisis of 2008), and an increased focus on careers, all of which are causing people to wait longer to start a family. How international governments will handle falling populations remains to be seen, but what is clear is that the declining birth rate is a multifaceted problem without an easy solution.

The fertility rate of a country is the average number of children that women from that country will have throughout their reproductive years. In the United States in 1800, the average woman of childbearing age would have seven children over the course of their lifetime. As factors such as technology, hygiene, medicine and education improved, women were having fewer children than before, reaching just two children per woman in 1940. This changed quite dramatically in the aftermath of the Second World War, rising sharply to over 3.5 children per woman in 1960 (children born between 1946 and 1964 are nowadays known as the 'Baby Boomer' generation, and they make up roughly twenty percent of todays US population). Due to the end of the baby boom and increased access to contraception, fertility reached it's lowest point in the US in 1980, where it was just 1.77. It did however rise to over two children per woman between 1995 and 2010, although it is expected to drop again by 2020, to just 1.78.

While the BRICS countries are grouped together in terms of economic development, demographic progress varies across these five countries. In 2019, India and South Africa were the only BRICS countries with a fertility rate above replacement level (2.1 births per woman). Fertility rates since 2000 show that fertility in China and Russia has either fluctuated or remained fairly steady, as these two countries are at a later stage of the demographic transition than the other three, while Brazil has reached this stage more recently. Fertility rates in India are following a similar trend to Brazil, while South Africa's rate is progressing at a much slower pace. Demographic development is inextricably linked with economic growth; for example, as fertility rates drop, female participation in the workforce increases, as does the average age, which then leads to higher productivity and a more profitable domestic market.

Japan’s ongoing struggle with rapid ageing is well known. Fertility and migration policies have both been proposed as solutions to Japan’s ageing population. We used stock flow population models to estimate the impact of hypothetical fertility and migration policy interventions on measures of aging in Japan from 2015 to 2050. We evaluated policy models based on the Old Age Dependency Ratio (OADR) they produced at the specified end date. Start dates ranged from 2020 to 2030 to assess the time horizons of individual policies. Fertility policies were found to be highly time dependent and only slowed the rate of increase of OADR. It would require a Total Fertility Rate far above replacement levels to compensate for Japan’s already aged demography. Migration policy was less time dependent. However, such measures would require unprecedented, and ultimately unrealistic, volumes of migration over coming decades in order to reduce Japan’s OADR. Our results suggest that fertility and migration based policy responses will be unable to significantly reduce Japan’s OADR or reverse Japan’s ageing population within the next few decades. Japan should focus on activating its human capital through the prolongation of working lives, increasing participation, and improving productivity within the Japanese labour force to mitigate and adapt to the inevitable effects of ageing populations.

In 2021, there were **** births per 1,000 people in Northern Ireland, compared with eleven in the previous year. Between 2000 and 2008, Northern Ireland's birth rate increased from **** to **** but started to decline gradually until 2012 when it dropped from **** to **** in just one year. During this provided time period, the birth rate in Northern Ireland was highest in 1971, when it was **** and was at its lowest in 2020 when there were just eleven births per 1,000 people. Falling birth rates in the UK For the United Kingdom as a whole, the birth rate fell to **** births per 1,000 people in 2020, before a slight uptick to **** in 2021. After a postwar peak of **** births per 1,000 people in 1964, the UK birth rate fell sharply to just **** by 1977. Between 1977 and 2012 the birth rate fluctuated between **** and ****, but declined in every year between 2012 and 2020. In 2021, the UK's fertility rate (the number of births per women) fell to just ****, compared with **** in 1964. Since 1973, the UK has fallen below the minimum replacement level fertility rate of ***, and without immigration would likely see its population decline in the long term. Global demographic trends The considerable decline in the UK's fertility rate in recent decades is not an isolated phenomenon. As of 2025, Africa was, at ****, the only continent to have a fertility rate higher than the global average of ****. Several countries, mainly in East Asia and Europe, have far lower fertility rates than the UK or the global average, however. South Korea provides the most dramatic example of this trend, with its fertility rate falling from **** in 1960 to just **** by 2020. By the *****, it is expected that, as Africa's fertility rate converges with the rest of the world, the global population will peak at around **** billion and start to decline.

In 2024, Monaco was the European country estimated to have the highest fertility rate. The country had a fertility rate of 2.1 children per woman. Other small countries such as Gibraltar or Montenegro also came towards the top of the list for 2024, while the large country with the highest fertility rate was France, with 1.64 children per woman. On the other hand, Ukraine had the lowest fertility rate, averaging around one child per woman.

Native Hawaiian and Pacific Islander women had the highest fertility rate of any ethnicity in the United States in 2022, with about 2,237.5 births per 1,000 women. The fertility rate for all ethnicities in the U.S. was 1,656.5 births per 1,000 women. What is the total fertility rate? The total fertility rate is an estimation of the number of children who would theoretically be born per 1,000 women through their childbearing years (generally considered to be between the ages of 15 and 44) according to age-specific fertility rates. The fertility rate is different from the birth rate, in that the birth rate is the number of births in relation to the population over a specific period of time. Fertility rates around the world Fertility rates around the world differ on a country-by-country basis, and more industrialized countries tend to see lower fertility rates. For example, Niger topped the list of the countries with the highest fertility rates, and Taiwan had the lowest fertility rate.

Abstract

The 2006-07 Sri Lanka Demographic and Health Survey (SLDHS) is the fourth in a series of DHS surveys to be held in Sri Lanka-the first three having been implemented in 1987, 1993, and 2000. Teams visited 2,106 sample points across Sri Lanka and collected data from a nationally representative sample of almost 20,000 households and over 14,700 women age 15-49.

A nationally representative sample of 21,600 housing units was selected for the survey and 19,872 households were enumerated to give district level estimates (excluding Northern Province). Detailed information was collected from all ever-married women aged 15-49 years and about their children below five years at the time of the survey. Within the households interviewed, a total of 15,068 eligible women were identified, of whom 14,692 were successfully interviewed.

The Department of Census and Statistics (DCS) carried out the 2006-07 SLDHS for the Health Sector Development Project (HSDP) of the Ministry of Healthcare and Nutrition, a project funded by the World Bank. The objective of the survey is to provide data needed to monitor and evaluate the impact of population, health, and nutrition programmes implemented by different government agencies. Additionally, it also aims to measure the impact of interventions made under the HSDP towards improving the quality and efficiency of health care services as a whole.

All 25 districts of Sri Lanka were included at the design stage. The final sample has only 20 districts, however, after dropping the 5 districts of the Northern Province (Jaffna, Kilinochchi, Mannar, Vavuniya, and Mullativu), due to the security situation there.

OBJECTIVES

The objective of this report is to publish the final findings of the 2006-07 SLDHS. This final report provides information mainly on background characteristics of respondents, fertility, reproductive health and maternal care, child health, nutrition, women's empowerment, and awareness of HIV/AIDS and prevention. It is expected that the content of this report will satisfy the urgent needs of users of this information.

MAIN RESULTS

FERTILITY Survey results indicate that there has been a slight upturn in the total fertility rate since the 2000 SLDHS. The total fertility rate for Sri Lanka is 2.3, meaning that, if current age-specific fertility rates were to remain unchanged in the future, a woman in Sri Lanka would have an average of 2.3 children by the end of her childbearing period. This is somewhat higher than the total fertility rate of 1.9 measured in the 2000 SLDHS.

Fertility is only slightly lower in urban areas than in rural areas (2.2 and 2.3 children per woman, respectively); however, it is higher in the estate areas (2.5 children per woman). Interpretation of variations in fertility by administrative districts is limited by the small samples in some districts. Nevertheless, results indicate that Galle and Puttalam districts have fertility rates of 2.1 or below, which is at what is known as “replacement level” fertility, i.e., the level that is necessary to maintain population size over time. Differences in fertility by level of women's education and a measure of relative wealth status are minimal.

FAMILY PLANNING According to the survey findings, knowledge of any method of family planning is almost universal in Sri Lanka and there are almost no differences between ever-married and currently married women. Over 90 percent of currently married women have heard about pills, injectables, female sterilization, and the IUD. Eight out of ten respondents know about some traditional method of delaying or avoiding pregnancies.

Although the proportion of currently married women who have heard of at least one method of family planning has been high for some time, knowledge of some specific methods has increased recently. Since 1993, knowledge of implants has increased five-fold-from about 10 percent in 1993 to over 50 percent in 2006-07. Awareness about pill, IUD, injectables, implants, and withdrawal has also increased. On the other hand, awareness of male sterilization has dropped by 14 percentage points.

CHILD HEALTH The study of infant and child mortality is critical for assessment of population and health policies and programmes. Infant and child mortality rates are also regarded as indices reflecting the degree of poverty and deprivation of a population. Survey data show that for the most recent five-year period before the survey, the infant mortality rate is 15 deaths per 1,000 live births and under-five mortality is 21 deaths per 1,000 live births. Thus, one in every 48 Sri Lankan children dies before reaching age five. The neonatal mortality rate is 11 deaths per 1,000 live births and the postneonatal mortality rate is 5 deaths per 1,000 live births. The child mortality rate is 5 deaths per 1,000 children surviving to age one year.

REPRODUCTIVE HEALTH The survey shows that virtually all mothers (99 percent) in Sri Lanka receive antenatal care from a health professional (doctor specialist, doctor, or midwife). The proportion receiving care from a skilled provider is remarkably uniform across all categories for age, residence, district, woman's education, and household wealth quintile. Even in the estate sector, antenatal care usage is at the same high level. Although doctors are the most frequently seen provider (96 percent), women also go to public health midwives often for prenatal care (44 percent).

BREASTFEEDING AND NUTRITION Poor nutritional status is one of the most important health and welfare problems facing Sri Lanka today and particularly affects women and children. The survey data show that 17 percent of children under five are stunted or short for their age, while 15 percent of children under five are wasted or too thin for their height. Overall, 21 percent of children are underweight, which may reflect stunting, wasting, or both. As for women, at the national level, 16 percent of women are considered to be thin (with a body mass index < 18.5); however, only 6 percent of women are considered to be moderately or severely thin.

Poor breastfeeding and infant feeding practices can have adverse consequences for the health and nutritional status of children. Fortunately, breastfeeding in Sri Lanka is universal and generally of fairly long duration; 97 percent of newborns are breastfed within one day after delivery and 76 percent of infants under 6 months are exclusively breastfed, lower than the recommended 100 percent exclusive breastfeeding for children under 6 months. The median duration of any breastfeeding is 33 months in Sri Lanka and the median duration of exclusive breastfeeding is 5 months.

HIV/AIDS The HIV/AIDS pandemic is a serious health concern in the world today because of its high case fatality rate and the lack of a cure. Awareness of AIDS is almost universal among Sri Lankan adults, with 92 percent of ever-married women saying that they have heard about AIDS. Nevertheless, only 22 percent of ever-married women are classified as having “comprehensive knowledge” about AIDS, i.e., knowing that consistent use of condoms and having just one faithful partner can reduce the chance of getting infected, knowing that a healthy-looking person can be infected, and knowing that AIDS cannot be transmitted by sharing food or by mosquito bites. Such a low level of knowledge about AIDS implies that a concerted effort is needed to address misconceptions about HIV transmission. Programs might be focused in the estate sector and especially in Batticaloa, Ampara, and Nuwara Eliya districts where comprehensive knowledge is lowest.

Moreover, a composite indicator on stigma towards HIV-infected people shows that only 8 percent of ever-married women expressed accepting attitudes toward persons living with HIV/AIDS. Overall, only about one- half of ever-married women age 15-49 years know where to get an HIV test.

WOMEN'S EMPOWERMENT AND DEMOGRAPHIC AND HEALTH OUTCOMES The 2006-07 SLDHS collected data on women's empowerment, their participation in decisionmaking, and attitudes towards wife beating. Survey results show that more than 90 percent of currently married women, either alone or jointly with their husband, make decisions on how their income is used. However, husbands' control over women's earnings is higher among women with no education (15 percent) than among women with higher education (4 percent).

In Sri Lanka, the husband is usually the main source of household income; two-thirds of women earn less than their husband. Although the majority of women earn less than their husband, almost half have autonomy in decisions about how to spend their earnings.

The survey also collected information on who decides how the husband's cash earnings are spent. The majority of couples (60 percent) make joint decisions on how the husband's cash income is used. More than 1 in 5 women (23 percent) reported that they decide how their husband's earnings are used; another 16 percent of the women reported that their husband mainly decides how his earnings are spent.

Impact of socioeconomic factors on desired fertility: Generalized poisson regression model analysis (N = 2,516).

This statistic shows the total population of Ecuador from 2020 to 2022, with projections up until 2030. In 2022, the total population of Ecuador amounted to approximately 17.72 million inhabitants. Ecuador's population The population of Ecuador continues to increase slowly but steadily. In 2014, the total population of Ecuador amounted to around 16 million. Yet, the population growth rate has been decreasing slightly since 2008. This means that more people have died than were born and/or more people have migrated out of as opposed to into the country. The fertility rate has been decreasing as well; ten years ago the fertility rate stood at around 3 children per woman, but today it stands at around 2.5 children per woman. This decrease has likely caused the slump in the population growth rate, even though it still remains above the natural replacement rate of 2, causing the population to still grow overall. Further, Ecuador’s life expectancy is around 76 years nowadays, with the percentage of adults aged over 65 years being less than seven percent (451305). The population of Ecuador is quite young, with about a third of the population under 14 years of age. The population is spread all over the country: Guayaquil and Quito are the largest cities in Ecuador and home to close to 4 million people combined. All other cities are smaller and the majority of them inhabit less than 250,000 people.

The statistic shows the total population of India from 2020 to 2030. In 2024, the estimated total population in India amounted to approximately 1.44 billion people. Total population in India India currently has the second-largest population in the world and is projected to overtake top-ranking China within forty years. Its residents comprise more than one-seventh of the entire world’s population, and despite a slowly decreasing fertility rate (which still exceeds the replacement rate and keeps the median age of the population relatively low), an increasing life expectancy adds to an expanding population. In comparison with other countries whose populations are decreasing, such as Japan, India has a relatively small share of aged population, which indicates the probability of lower death rates and higher retention of the existing population. With a land mass of less than half that of the United States and a population almost four times greater, India has recognized potential problems of its growing population. Government attempts to implement family planning programs have achieved varying degrees of success. Initiatives such as sterilization programs in the 1970s have been blamed for creating general antipathy to family planning, but the combined efforts of various family planning and contraception programs have helped halve fertility rates since the 1960s. The population growth rate has correspondingly shrunk as well, but has not yet reached less than one percent growth per year. As home to thousands of ethnic groups, hundreds of languages, and numerous religions, a cohesive and broadly-supported effort to reduce population growth is difficult to create. Despite that, India is one country to watch in coming years. It is also a growing economic power; among other measures, its GDP per capita was expected to triple between 2003 and 2013 and was listed as the third-ranked country for its share of the global gross domestic product.
