While overall low fertility rates are common in East Asian populations globally, within the U.S., Asian and Black women tend to have lower birth rates and higher rates of infertility compared to White women, with Black women facing greater disparities potentially linked to socioeconomic factors, untreated STIs, and delayed care, though data varies and shows complex patterns.
The term lowest-low fertility is defined as a TFR at or below 1.3. Lowest-low fertility is found almost mostly within East Asian countries and European countries. The East Asian American community in the United States also exhibits lowest-low fertility.
In our study, black women had a significantly higher odds of ever having experienced infertility than white women. Even after adjustment for socioeconomic position, marital status, and other risk factors for infertility, this disparity persisted.
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).
Glazer et al also demonstrated that Asians had the highest sperm concentrations and Blacks the lowest, similar to our data. Furthermore, additional studies have looked at Chinese populations but lack a comparator group,10 and Japanese populations with limited sample size of only 324 men.
Are certain ethnicities more fertile?
Racial disparities in health have been well noted, with blacks, in particular, having poorer health than whites across a broad range of outcomes.
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%).
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.
Asian women had slower active labor and reported less pain than women of other ethnicities. The researchers also found that women who weighed more generally had slower active labor. The study is in the November issue of Anesthesiology.
The rates for two major birth defects--anencephaly and ventricular septal defect--were highest among Asians. Among blacks, rates for six malformations were statistically significantly higher and rates for nine malformations were statistically significantly lower than rates among whites (Table 2).
Fertility is lower among interracial couples than among their endogamous counterparts. Fertility is lower among cohabiting than among married interracial couples. Fertility rates among interracial couples vary by race and gender of partners (i.e., by the extent of stigmatization or economic marginalization).
Fertility declines with age in both men and women, but the effects of age are much greater in women. In their 30s, women are about half as fertile as they are in their early 20s, and women's chance of conception declines significantly after age 35. Male fertility also declines with age, but more gradually.
The odds of pregnancy are reduced for Asians (odds ratio [OR], 0.86; 95% confidence interval [CI], 0.80–0.93), and the odds of live birth are reduced for all minority groups: Asian (OR, 0.90; 95% CI, 0.82–0.97), Black (OR, 0.62; 95% CI, 0.56–0.68), and Hispanic (OR, 0.87; 95% CI, 0.79–0.96) women in comparison to White ...
Black and Hispanic women are more likely than White or Asian women to suffer from secondary infertility, possibly because more Black and Hispanic have their first child at younger ages than White women (Mathews and Hamilton, 2009).
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).
Asian Americans and Native Americans have the lowest rates for twins. White people assigned female at birth have the highest rate of higher-order multiple births (triplets or more).
Genic variation within and between the three major races of man, Caucasoids, Negroids, and Mongoloids.
In 2021, 36.3 million children were White (49.4%); 18.9 million were Hispanic (25.7%); 10.1 million were Black (13.8%); 4 million were Asian (5.4%); 596,000 were America Indian/Alaska Native (0.8%); and 158,000 were Native Hawaiian/Other Pacific Islander (0.2%).
Abortion Rate by Race/Ethnicity
Non-Hispanic, black women have the highest abortion rate, accounting for over 38% of all abortions in the United States.
Results Estimated unintended pregnancy rates ranged from 11 (80% uncertainty interval: 9 to 13) in Montenegro to 145 (131 to 159) in Uganda per 1000 women aged 15–49 years. Between-country heterogeneity was substantial in all Sustainable Development Goal (SDG) regions, but was greatest in sub-Saharan Africa.
In 2019, the birth rates for Hispanic teens (25.3 per 1,000) and non-Hispanic Black teens (25.8 per 1,000) were more than two times higher than the rate for non-Hispanic White teens (11.4 per 1,000). The birth rate of American Indian/Alaska Native teens (29.2 per 1,000) was highest among all race/ethnicities.
Whites are usually taken as the standard against which other groups are compared, but they are not necessarily in the best health. Hispanics appear to be healthier than whites on a number of measures, though not all. Asians are generally in better health than any other group (Hummer et al., 2004).
American Indians in Western and Midwestern states have the shortest life expectancy as of 2021, 63.6 years. That's more than 20 years shorter than Asian Americans nationwide, who can expect to live to 84, according to a recent study by the Institute for Health Metrics and Evaluation at the University of Washington.
Of all the included foods, a beef hotdog in a bun was associated with the greatest loss of life per serving (−36 minutes), whereas a peanut-butter-and-jelly sandwich was associated with the greatest extension of life per serving (+33 minutes).
