What percentage of Americans have passports?
I was on business in the States about 5 years ago. A local told me that the 65% of the population of the city I was in had not left the city boundary and 85% had not left the state. Therefore no more than 15% of that city’s population would have had a passport. The statistic was regarded as slightly below national average because the traditional business of the area was farming. Most of the travel was done primarily because of work and business. As a consequence, most of those who do travel out of state or have passports do so because their work requires or required it in the past. I am not sure where this guys got his statistics from or how reliable they are. However, the anecdotal evidence he gave of his city/state certainly fits in with my observations.
