In Texas the most common job was secretary from 1978 t0 1990, and then it was truck driver.
What’s up with truck drivers ands secretaries?
Truck drivers dominate the map for a few reasons.
Driving a truck has been immune to two of the biggest trends affecting U.S. jobs: globalization and automation. A worker in China can’t drive a truck in Ohio, and machines can’t drive cars (yet).
Regional specialization has declined. So jobs that are needed everywhere — like truck drivers and schoolteachers — have moved up the list of most-common jobs.
The prominence of truck drivers is partly due to the way the government categorizes jobs. It lumps together all truck drivers and delivery people, creating a very large category. Other jobs are split more finely; for example, primary school teachers and secondary school teachers are in separate categories.
The rise and fall of secretaries: Through much of the ’80s, as the U.S. economy shifted away from factories that make goods and toward offices that provide services, secretary became the most common job in more and more states. But a second shift — the rise of the personal computer — reversed this trend, as machines did more and more secretarial work.
