From the Lawrence Daily Journal-World for July 24, 1971:
According to the 1971 Douglas County agricultural census figures just released, there were 54,420 people living in the county, with 42,152 of that number living in Lawrence. The agricultural census, coordinated by the Kansas Board of Agriculture, was constructed in such a way that it did not count most of the students of Kansas University, Haskell Indian Junior College and Baker University. The rules for the agricultural census were to "list unmarried students, minors and adults, whose parents are residents of Kansas, as inhabitants of the city in which their parents reside.” The federal census, on the other hand, listed every person living in a community on a given day. The 1970 federal census, conducted in the spring, had included area students in the enumeration.
