A recent survey by the Kenya Mini Demographic and Health Survey (KMDHS) reveals significant changes in marital status among Kenyan women aged 15 to 49 over the past 20 years. The proportion of women who are married or living with a partner has decreased from 60% in 2003 to 55%. This decline is attributed to a rise in the number of women who have never married, from 30% in 2003 to 32.9% currently.
The survey also indicates a sharp increase in divorce and separation rates. The combined rate of divorced or separated women rose from 6% in 2003 to 10%. Specifically, 8.2% of women are separated, while 1.4% are divorced. Additionally, 2.5% of women in this demographic are widowed. These changes reflect evolving family structures and shifting social norms in Kenya.
Despite legal frameworks recognizing marriage, a significant gap exists in the registration of unions. Only 17.6% of married or cohabiting women reported registering their union, with just 14% possessing a formal marriage certificate. Urban women are more likely to register their marriages, with 22.6% doing so, compared to 13.6% of rural women. This disparity highlights a need for improved legal registration processes, especially in rural areas.
The KMDHS also provides insights into county-level marriage registration rates. Garissa and Isiolo counties have the highest registration rates, at 53.8% and 52.8%, respectively. In contrast, Wajir and Vihiga counties have the lowest rates, with 2.8% and 5.0% of women registering their marriages. These disparities underscore regional variations in marriage registration practices across Kenya.
The survey tracks behavioral patterns among young women aged 15 to 24, focusing on sexual behavior and higher-risk intercourse. Overall, 2.2% of women in this age group reported having two or more sexual partners in the year preceding the survey. The rate increases with age, from 0.9% among 15-19-year-olds to 3.5% among 20-24-year-olds. Ever-married young women are more likely to report multiple partners than those who have never married.
The KMDHS also highlights a decline in Kenya's total fertility rate, which has dropped to 3.1 children per woman in 2025, down from 3.4 in 2022 and 4.9 in 2003. Urban women have an average of 2.6 children, compared to 3.6 children per woman in rural areas. Embu leads the country with the lowest fertility rate at 2.2 children per woman, while Mandera recorded the highest rate at 6.8 children per woman.
The survey's findings have implications for policymakers and stakeholders. The decline in marriage rates and rise in separations may be linked to changing social norms and economic factors. Additionally, the low registration of marriages and high rates of higher-risk intercourse among young women highlight the need for targeted interventions and education programs to promote healthy relationships and family planning.
