It would be interesting (and relevant) to know what percentage of white parents of school aged children are for busing.
The GSS doesn’t ask respondents about the ages of their children but it does ask about whether or not they have any.
Mean support for mandated busing from 1972 through 1996:
As previously noted, support for busing steadily increased over the period of time in question. The figures above are averages for the entire time period. If the trendline from the seventies through the mid-nineties continued, the contemporary figures will be higher than these (among whites, anyway).
GSS variables used: BUSING, SEX, POLVIEWS(1-3)(4)(5-7), RACE, CHILDS(0)(1-8)
