Black Last Names Starting With O

Here are the most common Black or African American last names beginning with O in the United States.

Our list takes surnames from the 2010 census only if 50% or more holders declared that they were Black.

Of course, many African Americans have surnames that fall below this percentage. We simply use it as a cut-off for this list.

Details Behind The List

The U.S. census of 2010 included a question that asked if the person was Black or another ethnicity (or mix).

Our details include the black percentage in 2010 for each name. The census provides a percentage with two decimal points. We rounded it to a whole number.

We also checked the censuses of 1940 and 1910 for the number of people of each name who were documented as black.

This article uses the terms Black and African American interchangeably.

The public details from the 2010 census do not include nationality so our numbers cannot be exact. Take them as a guide.
