The American Population in 1800

According to the estimate of Reynolds, the American population in Illinois in the year 1800 amounted to eight hundred souls. The New Design and American Bottom settlements, in the present county of Monroe, contained six hundred inhabitants, and there were other scattering settlements in that county. Only about one hundred Americans lived in Randolph County. Of these, six or eight families lived in Kaskaskia. The settlement east of the Kaskasia river contained seven families, and the Horse Prairie colony was still less in number.
