According to the 1860 U.S. Census, there were 250,787 free blacks living in the South in contrast to 225,961 free blacks living everywhere else in the country including the Midwest and the Far West; however, not everyone, particularly free blacks, were captured by census takers. In the upper south, the largest population of free blacks were in Maryland and Virginia; in the mid-Atlantic, the largest population of free blacks was in Philadelphia.
