Will your area survive a technological collapse? I’ve a quick and dirty rule of thumb for figuring it out. How much population did your area support long ago before the electronic age?
Here’s what I did for my area: Coos County New Hampshire. According to the 1910 census there was a population of about 30,000 people. Today there’s about 31,000. The land should be able to support the current population at at 1910 technology level.
It’s a very rough estimate but like all rules of thumb is a good place to start. There have been changes in the land since 1910. For example, there’s a lot more forest than there was in 1910. However, there’s also less farmland. On the bright side wood from that forest could keep us from freezing during the winter. We are blessed with abundant fresh water and that counts for a lot.
Some places you know are going to be in deep trouble. Take Los Vegas for example. How many people could the desert support back in the day? It’s a tiny fraction of the number of people who live there now. Some places the only sensible thing will be to bug out.
Big cities are pretty much screwed. Just hope technology does not take too hard a hit. There are a lot of rural areas that are less populated than they were 100 years ago. With modern farming methods it takes just a few percent of the farm population to feed people. Everyone else moved to the cities.
There are areas in the country that once supported sizable indigenous populations. If you live in one of those areas it wouldn’t hurt to study how they did it.
Another thing to take into account is the fact that a big part of the country has been in serious drought. During those times populations tend to crash and societies fall apart. Only technology and the vast resources and size of the country have keep those areas viable today.
Old census data is readily available on-line. It might be revealing to see how and how many people survived.
At any rate, it’s a good thought experiment.
