Beginning in 1923, Mississippi enumerated students every two years (i.e., 1925, 1927,
and so on). The records show a student’s age as of January 1 of the year instead of
as the date of the census. The records for Humphrey’s County, MS, may appear to show
enumeration data for 1924, but the age shown on the record is actually the age as
of 01/01/1925.
