Fun With Statistics

Here's an article pointing up the shortcomings of a PIRG survey claiming that the 20-29 generation is showing a happy aversion to driving those evil cars and moving to suburbia. The problem with the study is that there was no correction for unemployment. An employed millennial will drive about 12,000 miles a year as opposed to one with no job who will drive only about 6,000.

Post hoc ergo propter hoc. The only conclusion they left out was the millennials obvious preference for unemployment.

Complete Colorado could also conclude that its readers exhibit a strong preference for Facebook membership since all their commenters are Facebook members. Ignoring of course that Facebook registration is required to post a comment.

I would also like to see how the driving distance correlates with residence -- whether living with parents or rent free, vs. single, with a roommate, or married, and whether there are children in the home.

But then, I would like to see a breakdown for people living in the home of their parents vs. short (less than 5 years) and longer term (more than five years), all vs. employment and short (less than two miles) and longer (over two miles) commutes. I expect this demographic to be changing noticeable as the afermath of the Obama administration settles out over America.
