Muslim and Arab Fertility Trends in the U.S. (2025): Family Size Trends & Demographic Profiles
Exploring fertility patterns among U.S. Muslims and Arabs: What the data tells us about average children per family.
In 2025, America faces one of the lowest fertility rates in its history, yet Muslim and Arab communities stand out for their relatively strong family growth. Unlike the national average of fewer than two children per woman, many Muslim and Arab families continue to raise larger households, influenced by both cultural expectations and immigrant generational patterns.
1. Overall U.S. Fertility Context (2025)
The total fertility rate (TFR) in the U.S. has continued its downward trend, declining to a record low of approximately 1.60 children per woman in 2024. Despite this, births rose slightly to over 3.6 million — indicating that population growth still persists due to immigration and natural increases.
2. Muslim Fertility Patterns
While exact figures for Muslims are not frequently updated, a Pew estimate indicates that as of earlier research, the average fertility rate among all U.S. Muslims was approximately 2.5 children per woman. This average is derived from weighting fertility rates for foreign-born Muslims (2.6) and U.S.-born Muslims (2.2).
Additional insight from Religion Unplugged suggests that among reproductive-aged Americans (35–45), Muslims—together with Mormons—average about three children per family, exceeding the national norm of two.
3. Fertility Among Arab Americans
Data specific to fertility trends of Arab Americans isn’t widely documented in public sources. However, broader context indicates that many immigrants from Middle Eastern and North African regions initially display higher birth rates, though these rates often decline over time and across generations.
4. Generational and Cultural Dynamics
-
Immigrant Muslim families contribute significantly to higher U.S. fertility rates, especially given that immigrant fertility typically falls during subsequent generations as education and assimilation increase.
-
The higher fertility among Muslims may also reflect cultural and religious values that favor larger families, especially among first-generation immigrants.
Summary Table
| Group / Context | Avg. Children per Woman (TFR) |
|---|---|
| U.S. Total (2024) | ~1.60 |
| All U.S. Muslims (Pew estimate) | ~2.5 |
| Muslims & Mormons (ages 35–45) | ~3 children per family |
| U.S.-Born Muslims | ~2.2 (Pew proxy) |
| Immigrant Muslims (U.S.) | ~2.6 (Pew proxy) |
| Arab American Fertility | No precise national data; likely reflects immigrant patterns |
Conclusion
As of 2025, U.S. Muslims—particularly immigrant communities—tend to have larger families than the national average. While the overall U.S. fertility rate hovers around 1.6 children per woman, Muslim women have an estimated fertility rate near 2.5, with those in prime childbearing ages averaging closer to three children per family. Cultural values and generational shifts play key roles in shaping these dynamics. Although specific data on Arab Americans is limited, their initial fertility patterns likely align with broader immigrant trends.
