The low population also means that there are not a lot of specialized jobs . People who make a good living here do it off tourism, by commuting, or by doing an assortment of things. Because we have limited services here there is a demand for people to do those odd jobs. Flexibility is required for getting a job, or for self-employment. There are a lot of small niches left here, and if you can fill more than one, you have a chance of building a stable business.
Businesses can also survive by marketing to non-local markets.
Our town covers an area about 8 blocks long, by about 6-7 blocks wide . If you run up one street, and down the other, the long way, you can put in just about a mile, round trip. That is about all the details I can think of right now.
