In fact, the seeds of conflict were already being sown at this point, as the reality of slavery, particularly in the Southern states, impacted the discussion of population during the Constitutional Convention—specifically who would be counted and who would not (“excluding Indians not taxed,” U. S. Constitution, Article 1, Section 2, Clause 3), or who would be counted partially (“three fifths of all other [unfree, i.e., enslaved] Persons.” In 1770, the population of the colonies was around 2 million (Roark et al., p. 138), but the slave percentages of the populations of each region—New England, the Middle colonies, and the Southern colonies—varied considerably. In New England, slaves were 3% of the total population of roughly 500, 000 (Roark et al., p. 142); in the Middle colonies, they were around 7% of the total population of roughly 430,000; but in the Southern colonies, slaves constituted 40% of the total population of roughly 1,000,000. Based on raw numbers, the Southern colonies should have been apportioned the same number of members of the House of Representatives as New England and the Middle colonies combined. Because of the three-fifths clause, the population of the Southern colonies in 1770 was reduced to 600,000 free and 240,000 enslaved, making a total of 840,000—still a significant proportion of the entire colonial population. The Constitution, therefore, bears witness to the tension that existed between the states due to their varying demographies, a tension that would grow knottier over the following 90 years. The nation’s leaders had attempted to forge a political unity among the colonies, one that accommodated the socioeconomic status quo in each. The Southern colonies remained agricultural, and later Southern states adopted a similar economy as conditions were found to be favorable. However, population growth in the South began to lag behind that in the North, and not just because the former region was almost entirely rural. Certain Southern agricultural practices were unsustainable: the historian Alan Kulikoff (1986, pp. 47–48) describes how eighteenth-century tobacco planters in the Chesapeake region, for example, rotated fields rather than fertilize them, with the result that the land became exhausted by the middle of the century, thus impelling planters to move in search of new land. Obviously, the Chesapeake area did not become deserted, but nor could it support any substantial increase in population. And yet Southerners saw no reason to make a change.
