Kenya has an estimated population of 54,227,015 according to the Kenya National Bureau of Statistics (KNBS), equal to approximately 0.71% of the world’s population. Kenya’s total land area is 569,140 km².

Population Growth Rate 

Kenya’s population has been increasing by about 1.92% yearly. This percentage is equal to over a million people annually. This steady increase can be attributed to a combination of factors, including declining but still relatively high fertility rates and improved healthcare leading to lower mortality rates.

Population Density 

Kenya’s population density is 94 per Km², 245 people per mi². Kibera is the densest place in Kenya with around 70,000 people per square kilometre. This makes the slum the densest in Africa and the second-largest globally.

Nairobi and Mombasa have a population density of over 5000 per square kilometre. Apart from Vihiga, all the other counties have a density of less than 1000 per square kilometre.

Marsabit has the sparsest population, with a density of 6 people per square kilometre. Tana River County follows closely with a population density of 8 people/ Km². The low population in these regions can be attributed to adverse climatic conditions.

Ethnic Groups and Diversity

Kenya has a diverse population with different cultures comprised of various ethnic and racial groups. These are the Bantus, Nilotes, Cushites, Indians, Arabs, and Europeans.

The largest ethnic group is the Kikuyu, a Bantu community. They comprise about a fifth of the population, followed by the Luhya, Kalenjin, and Luos.

Bantu communities include Kikuyu, Kamba, Kisii, Meru, and the Mijikenda, making up Kenya’s largest population division.

The second grouping is the Nilotes. They comprise the Luo, Maasai, Samburu, Kalenjin and Turkana. They have a similar governing structure to their Cushite neighbours.

The third-largest group is the Cushite, who came from Ethiopia and Somalia. They are subdivided into Southern and Eastern Cushites. The Southern Cushites, in their migration, wound up in Tanzania, which leaves on Eastern Cushites in Kenya. They include the Oromo and the Somali. The Somalis are an entrepreneurial community and have established themselves in the business sector.

Apart from those three groups, Kenya has many Asians living here. According to the census, there are about 47,555 Indians in the country, and in 2017 were recognized as the 44th Kenyan tribe. Kenya also has many European settlers, primarily the British, who are descendants of the migrants in the colonial period. The country also has a large expat community.

Finally, there is a small Arab community in Kenya located in the coastal region. They are a Muslim community from Yemen, Oman, and Hadhramut.

Languages Spoken 

There are two official languages in Kenya which are English and Swahili. However, Swahili is more widely spoken compared to English. It is a language native to East Africa, locally known as Kiswahili. It is a Bantu language with borrowed words from Arabic, English, German, and Persian.

Migration Patterns

Kenya loses about 26,000 people annually to external migration, with 27,330 people in 2025. However, the country experiences more internal migration. The coastal region has experienced the highest migration percentage at 59.5% in urban areas.

There’s also a lot of rural-urban migration, which has increased the urban population to about 14,975,059. Males predominantly outnumber females in rural-to-urban migration driven by the desire for better education and economic opportunities.

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.

Life Expectancy

Life expectancy at birth is a crucial demographic indicator. This data shows the number of years an infant is expected to live if the birth and death rates remain constant during their lifetime.

Kenya’s life expectancy has been increasing over the years. The current life expectancy for Kenya in 2026 is 64.2 years, with 62.0 years for males and 66.5 years for females.

Gender Distribution

Kenya’s population in 2026 stands at approximately 54.2 million people. Contrary to the popular belief that the ratio of men to women in Kenya is 1:7, the population is almost the same. The population sex ratio is 0.998, meaning 998 males per 1000 females.

This ratio is lower than the current global ratio of approximately 1,010 males to 1,000 females as of 2026. However, gender inequality in public offices is still prevalent.

Household Income Distribution

Though Kenya has the fastest number of growing super-rich in the region, there is still a huge income disparity. As of 2026, the average monthly income for households is Sh25,368.

However, the gap between Kenya’s rich and poor is still high. Less than 0.1% of the population own more wealth than the bottom 99.9%. The best employers in Kenya are International NGOs and financial sectors in the formal environment, with lowest paying jobs being in the household sectors.

This sector employs domestic workers. Other low earners include those in the real estate, water supply, and waste management sectors. The agricultural industry is also one of the largest employers, and workers earn an average of Sh.  31,469 per month.
