Including PT workers is going to skew the numbers quite a bit. Most PT workers will not have paid time off, so if you're part-time you're likely to work 51 or 52 weeks unless you are employed seasonally.
And 34.5 hours may be the mean, but most workers are either going to be full-time 40+ hr/week or substantially less than that. Most PT job ads I've seen are for 10, 15, or 20 hours of work a week. 30 is very high, so the vast majority of workers are not going to work any close approximation of 34.5 hours a week.
Most of the sources I can find online are either using the "any type of worker" number of 1750-1800 hrs/yr, or 2k+ for FT only (which is approximately 50 wks/yr).
What is your goal here? I think you agree with me that "Not to be pedantic .. the average full time worker only works 1700 hours a year" is actually incorrect, yes?
Are you trying to judge the accuracy of "an average American who works 50h a week,50 weeks out of the year"? If so, the second link I gave, to the Gallup poll, addresses that somewhat (see http://www.gallup.com/poll/175286/hour-workweek-actually-lon... ).
The question is "in a typical week, how may hours do you work?" Employed full-time said 46.7 hours, and employed part-time said 25.9 hours. Further, "Forty-three percent of U.S. adults in the August 2014 survey tell Gallup they are employed full time, down from about 50% in the Work and Education polls conducted each August before the 2007-2009 recession. Meanwhile, the percentage who work part time has consistently hovered near 9%." I figure that as:
so the average working American works 43+ hours per week. Certainly not as extreme as 50 hours per week, but then again, as you point out, there's a skew to the numbers; and "average" could mean mean, or median, or even mode.
How do PT ads for "10, 15, or 20 hours of work a week" add up to that much time? I suspect that many part-time employees have multiple part-time jobs.
It's also true that people may lie to Gallup pollsters.
