Vietnam: Student Opinion about the Vietnam War
Description
A survey of student opinion on the Vietnam War was taken at the
University of North Carolina at Chapel Hill in May 1967 and published
in the student newspaper. Students were asked to fill in ballot
papers stating which policy out of A,B,C or D they supported.
Responses were cross-classified by gender/year.
The response categories were:
[object Object],[object Object],[object Object],[object Object]source

For some analyses, it is useful to treat year
as numeric,
and possibly assign grad students a value year=7
