Formal rules and informal customs created innumerable obstacles to the socioeconomic advance of Virginia's free black population. Laws prohibited free blacks from some activities and occupations and restricted their participation in others. Racism and Klan-like terrorism also made advancement difficult.

Primary sources and the secondary literature are consistent with the anthropometric evidence.
