Origin
The surname NJUGUNA is of Kenyan origin, specifically from the Kikuyu tribe. It is believed to have originated in the late 18th or early 19th century, deriving from the Kikuyu word 'njuguna,' which means 'one who travels far and wide.'
The name is thought to have been given to individuals or families who were known for their wanderlust and adventurous spirit, often traveling long distances for trade, exploration, or in search of new opportunities. The Kikuyu people have a rich oral tradition, and it is likely that the earliest records of this surname were passed down through storytelling and oral histories.
One of the earliest known references to the name NJUGUNA can be found in the writings of Johann Ludwig Krapf, a German missionary who lived and worked among the Kikuyu people in the mid-19th century. In his journals, Krapf mentions encountering individuals with this surname, indicating its prevalence in the region during that time.
Notable individuals throughout history who bore the surname NJUGUNA include Jomo Kenyatta (1894-1978), the first Prime Minister and later President of independent Kenya. Kenyatta was a prominent figure in the Kenyan independence movement and played a crucial role in the country's transition to self-governance.
Another significant figure was Ngugi wa Thiong'o (born 1938), a renowned Kenyan writer, academic, and social activist. Ngugi has been a leading voice in postcolonial literature and has written extensively on issues of language, culture, and identity.
Wangari Maathai (1940-2011), an environmental and political activist, was the first African woman to receive the Nobel Peace Prize in 2004 for her contributions to sustainable development, democracy, and peace.
In the world of athletics, Henry Rono (born 1952) was a legendary Kenyan middle and long-distance runner, holding multiple world records in the 1970s and 1980s. He is considered one of the greatest distance runners of all time.
Lastly, Raila Odinga (born 1945) is a prominent Kenyan politician and former Prime Minister, known for his long-standing involvement in the country's political landscape and his advocacy for democratic reforms.
Demographics
Among Census respondents with the surname Njuguna, the largest self-reported group is Black at 94.3%. The next largest groups are White (2.5%) and Two or More Races (2.5%).
The bar chart below shows how Njuguna bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Njuguna surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Njuguna (2000, 2010, 2020).
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
