Since I have internet service and a computer, I took my own advice and took the time to learn that, indeed, the truckdriver statistic is not true.
Not just because of boilerdown's comment, but because the person who produced this statistic for NPR did not correctly account for aggregated data from the Bureau of Labor and Statistics (BLS) data. The data for truckdriver was aggregated, but the data for other jobs remained broken into the subset within the entire job description.
For example, the different nursing specialty jobs were not combined into a total nursing category and different teaching (elementary, middle school, high school) jobs were not combined into "teachers."
So, in 42 states, retail salesperson is the most common job. There are more cooks, cashiers, office workers, secretaries, waitresses, janitors and other workers than truck drivers.
So, Zoney is correct. WTG Zoney.
I didn't think of the aggregates. Good call. Apologies to Zoney, if he was upset at me.
