MS (DLC); in Winthrop Sargent’s hand, except for totals which were inserted in pencil by TJ. Printed in New-York Journal, 31 Jan. 1791. St. Clair estimated the population of the french settlement, left blank in Sargent’s tabulation, at “about four hundred” (see enclosure, Document viii). A census of 1791 showed a total of 347 persons, 237 males and 110 females. Half of these were between 20 and 40 years of age, almost a third were between 1 and 20, and 29 were infants (J. Guion, “Etat de la population de la Colonie françoise,” 20 May 1791, MHi: Sargent Papers).
