These reports from some two-score scattered localities enumerate 2456 slaves, about one-third of the total negro population of the specified age; and they yield unusually definite data as to the scale of slaveholdings.

Lewis Morris of Morrisania had twenty-nine slaves above fourteen years old; Peter DeLancy of Westchester Borough had twelve; and the following had ten each: Thomas Dongan of Staten Island, Martinus Hoffman of Dutchess County, David Jones of Oyster Bay, Rutgert Van Brunt of New Utrecht, and Isaac Willett of Westchester Borough.

Seventy-two others had from five to nine each, and 1048 had still smaller holdings.[34] The average quota was two slaves of working age, and presumably the same number of slave children.

That is to say, the typical slaveholding family had a single small family of slaves in its service.

From available data it may be confidently surmised, furthermore, that at least one household in every ten among the eighty-three thousand white inhabitants of the colony held one or more slaves.
