How can I learn about an occupation that is of interest to me?
The Occupational Outlook Handbook (OOH) provides information on what workers do; the work environment; education, training, and other qualifications; pay; the job outlook; information on state and area data; similar occupations; and sources of additional information for more than 300 occupational profiles covering about 4 out of 5 jobs in the economy.
As for answering the question, anecdotal conversations I’ve had suggest that the trades (eg glazier, electrician, plumber) in the USA are promising fields, since while the nature of the job might change with different needs, people still require electric wires and piped water. But the OOH could give you more specific outlooks for those specific trades.
I was once told that plumbers can make very serious sums of money, even if they’re only ever installing supply-side piping. That is to say, the plumbing for water supply, as compared to drainage or sewer pipe, which are generally perceived as less appealing.
