I divided them into four groups, with divisions indicated by the blank lines. The last group of occupations corresponds with what people normally call "blue-collar"--they involve making or extracting some tangible product. The first and third groups would clearly be "white collar" jobs--the difference is that the first generally involves more skill and higher pay than the third. The second group is hard to classify by the blue collar/white collar distinction--like most white-collar jobs, they produce services rather than goods, but in terms of skills and autonomy, they are closer to blue-collar jobs.
The occupational distribution of people with different amounts of education (rearranging the order to put the two white collar groups together):
Manager/Prof Other Service Blue-Collar
Not HS graduate 7% 17% 34% 41%
HS only 19% 25% 22% 34%
Some College 29% 31% 21% 19%
College Grad 64% 22% 8% 7%
Master's 84% 10% 3% 3%
Professional/Doctoral 92% 4% 2% 1%
Few blue-collar workers have college degrees, but a lot of people without college degrees are NOT blue-collar workers. Considering everyone without a college degree, only 29% are blue-collar workers in the narrow or traditional definition. Another 23% are service workers, so on a broader definition you could say a little over half are blue-collar workers.
The reason that lacking a college degree is not synonymous with having a blue-collar job is partly that there just aren't that many blue-collar jobs in the United States any more, and partly that even people with only a high school diploma have a decent chance of obtaining a white-collar job (which might involve supervising blue-collar workers).
Looking at it from one direction, it's strange that given the contemporary interest in class, few surveys bother to ask people what kind of work they do. Looking at it from another direction it's strange that when given a straightforward measure of education, people call it "class" rather than "education."
