Origin
The surname AJAYI originates from the Yoruba people of southwestern Nigeria. It can be traced back to the 15th century in the region that is now modern-day Ogun State and Lagos State. The name is derived from the Yoruba word "Aja," meaning a skilled person or warrior, and "Iyi," meaning to live or reside.
The earliest recorded instances of the AJAYI surname can be found in oral traditions and historical accounts from the Oyo Empire and the Ijebu Kingdom. The name is associated with notable warriors, chiefs, and community leaders during this era. One of the earliest documented individuals bearing the name was Ajayi Ogundele, a renowned warrior and military commander who lived in the late 16th century.
Throughout the 17th and 18th centuries, the AJAYI name appeared in various records and manuscripts kept by local chiefs and rulers in the Yoruba region. These documents often chronicled important events, lineages, and the exploits of notable individuals within the community.
In the 19th century, the name gained further prominence with individuals such as Ajayi Crowther (1809-1891), a renowned linguist, scholar, and the first African bishop of the Anglican Church. Another notable figure was Ajayi Agbede (1845-1917), a prominent trader and community leader in the city of Lagos.
During the 20th century, several individuals with the AJAYI surname made significant contributions in various fields. These include Ajayi Ade Akinwande (1900-1962), a respected educator and writer; Ajayi Crowther Awolowo (1909-1967), a prominent Anglican priest and theologian; and Ajayi Festus Ajayi (1927-2021), a renowned historian and academic who served as the Vice-Chancellor of the University of Lagos.
Other notable individuals with the AJAYI surname include Ajayi Babalola (1904-1959), a renowned evangelist and founder of the Christ Apostolic Church, and Ajayi Bamidele (born 1954), a Nigerian politician and former member of the House of Representatives.
Demographics
Among Census respondents with the surname Ajayi, the largest self-reported group is Black at 94.4%. The next largest groups are Two or More Races (2.2%) and White (1.9%).
The bar chart below shows how Ajayi 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 Ajayi surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
