The country has also experienced increased international immigrants seeking to set up businesses or settle there. There are also irregular border movements that are hard to control which has seen an increase in undocumented foreigners.

Fertility Rate

In many countries, the fertility rate has steadily reduced in recent decades. Factors such as the age at which women have a first child and marriage have hugely affected the fertility rate.

Over the last few years, Kenya’s fertility has declined by about 1.55%. Currently, the fertility rate for Kenya in 2023 is 3.259 births per woman, a 1.57% decline from 2022.
