Niger consistently has the world's highest fertility rate, with estimates for 2024 around 6.64 children per woman, followed closely by other Sub-Saharan African nations like Angola, the Democratic Republic of Congo, Mali, and Somalia, reflecting high rates across the broader African continent.
All figures are estimates. In 2024, the fertility rate in Taiwan was estimated to be at 1.11 children per woman, making it the lowest fertility rate worldwide. The fertility rate is the average number of children born per woman of child-bearing age in a country.
In the United States, the highest fertility rates (per 1,000 women ages 15-44) during 2021-2023 (average) were to Hispanic women (64.4), followed by Blacks (55.2), Whites (52.5), American Indian/Alaska Natives (49.3) and Asian/Pacific Islanders (48.1).
High fertility rates in Africa
With a fertility rate of 6.13 and 6.12 children per woman, Somalia and Chad were the countries with the highest fertility rate in the world. Population growth in Chad is among the highest in the world.
The highest fertility levels are observed in Niger (13.6 children on average), South Sudan (13.5 children), Chad (12.1 children) and in the Sahelian countries more generally. In only four countries (South Africa, Botswana, Lesotho and Namibia) is male fertility below 6 children per man.
Results. Significant racial differences for various parameters including the incidence of normal ranges values in the racial groups were found. The highest mean sperm concentration had men of Central/South Asian descent (median: 38.0 × 106/mL) while Southeast Asian men had the lowest (median: 22.0 × 106/mL; p < 0.0001) ...
A complete lack of sperm occurs in about 10% to 15% of men who are infertile. A hormone imbalance or blockage of sperm movement can cause a lack of sperm. In some cases of infertility, a man produces less sperm than normal. The most common cause of this condition is varicocele, an enlarged vein in the testicle.
In 2022, teen birth rates of American Indian/Alaska Native, Native Hawaiian/Other Pacific Islander, Black, and Hispanic adolescents were more than double the rate for White adolescents, and more than 10 times higher than the rate among Asian adolescents.
There are three major reasons for the rapid decline in the global fertility rate: the empowerment of women — increased access to education and increased labor market participation. declining rates of child mortality. rising costs of bringing up children, with the decline of child labor.
Results. Among the non-surgically sterile sample of women (n=489), more black women than white women reported infertility (48% vs. 31%; p<0.001). Black women were slightly younger and less often ever married and nulliparous, and more often had low income, lower education, and difficulty paying for basics (39.4 vs.
Hispanics have the youngest, 27.6. Non-Hispanic blacks (32.9) and non-Hispanic Asians (35.9) also are younger than whites. Related to their younger age profiles, racial and ethnic minority groups also include a higher share of women in the prime child-bearing ages of 20-34.
Racial disparities in health have been well noted, with blacks, in particular, having poorer health than whites across a broad range of outcomes.
Ranked: Countries With the Fewest Children by Population Share. Hong Kong (12.6%), South Korea (12.9%), and Japan (14.0%) have the fewest children as a share of the population in 2025. Relatedly, they also have some of the highest shares of seniors.
People are marrying later and also worried about their ability to have the money, health insurance and other resources needed to raise children in a stable environment. "Worry is not a good moment to have kids," and that's why birth rates in most age groups are not improving, she said.
stated that a research study found that women, on average, could have around 15 babies in their lifetime.
Telegram founder Pavel Durov told French media earlier this year that he has more than 100 kids around the world, mostly from babies conceived through his sperm donations.
Actors Dax Shepherd and Kristen Bell have daughters Lincoln, born in 2013, and Delta, born in 2014. The couple keeps their kids very private. When they do post pictures with them on social media, they make sure to cover their faces to ensure as much privacy as possible.
The majority (66%) of births to black mothers were characterized as unintended, compared with roughly one-third of births to whites (36%) and Asians (33%), and about one-half of those to Hispanics (46%) and women of other races and ethnicities (53%).
From a biological point of view, studies establish that the best age to have children with the least amount of complications in pregnancy and post-partum, is between 25 and 29.9 years old. Indeed, female fertility reaches its peak levels within this age range.
More than 80% of teen pregnancies are unintended. Over half of unintended pregnancies were to women not using contraceptives, most of the rest are due to inconsistent or incorrect use.
Symptoms
Men can produce sperm throughout their lives, so there is no “male menopause” when men can't have children any longer. But that said, studies have shown that male fertility does decline with age. If a man is over age 45, it can take five times longer for he and his partner to conceive than if he was aged 25 or under.
Fruits and veggies
A study of 250 men who had sperm analyzed at a fertility clinic showed that men who ate higher amounts of fruits and veggies, particularly green leafy vegetables and beans (legumes), had higher sperm concentrations and better sperm motility compared to men who ate less of these foods.
