*  The north latitude for Mississippi that appears in the source material appears to be an error but is displayed here as in the report. The description accompanying the center of population in the source material states it is 3.5 miles SE of Sallis, Attala County, Mississippi which does not correspond to the north latitude. We believe the correct north latitude is 32° 59′ 52″.
