I suspect that location has a lot to do with the ratio of licensed to unlicensed youths. As people gravitate to larger metro areas with good public transportation the need for a driver's license goes down.
I've always lived in largely rural areas, which made having a driver's license a necessity and I got mine immediately. The state I lived in at the time allowed full licensing at the age of 14 and the town we lived in did not provide busing for high school students so having a car and a license was pretty much the only way we were getting to school.
Driver's ed was optional but most insurance companies offered reduced insurance rates for kids who went through it. I already had my license but was forced to take it for the premium reduction. I took it as a summer course and rode my motorcycle every day to the class. If I remember right I was the only student who didn't get dropped off for class every day.
