TABLES & GRAPHS
The following pages contain a series of tables and graphs. The first section consists of tables and graphs showing how the percentage of blacks (both free and slave) in each region and state changed over time. These graphs group the states within a region together on a single chart. This allows the reader to look for differences from state to state in the same region, or from region to region within the nation.
The second section provides tables and graphs of raw numbers of free blacks, slaves, and the total population, by state and region. These tables and graphs are useful for studying the way in which black populations changed not only as a percentage, but in absolute numbers.
Nearly all of the states in these graphs and tables correspond to their current boundaries--even if the area in question was not yet a state. Thus, Maine's data is as though it was a state in 1790, even though it was still a part of Massachusetts. Similarly, the Census Bureau adjusted data for territories to correspond to the boundaries of the appropriate modern states. There are two significant exceptions: New Mexico and Virginia.
In these tables and graphs, New Mexico Territory includes the modern states of Arizona and New Mexico. The states of Arizona and New Mexico were just forming when the Census Bureau produced the raw data used in producing these tables. Because they did not provide a breakdown into the Arizona and New Mexico state equivalents, this work is also unable to do so. Virginia's and
