These data indicate:

No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	19-25*	1794-1801	= George
1 female	16-25	1794-1804	= Sister Catharine
1 female	45 or over	in or bef. 1775	= Anna Maria (b. ca. 1747)
1	person engaged in agriculture
*In the 1820 Census, the third column is age class 16-18 and the fourth column is age class 16-25; therefore, any individual in column three is duplicated in column four.  By subtracting the number in column three from the number in column four, you can create an age class "19-25."

George is old enough to be married, so the young female may be a prior wife, but his sister, Catharine, didn't marry until 1825, so it's probably she.  Listed next to George's brother, Henry STROOP.

George's age appears to be inflated here because in all earlier censuses he is younger.
