That huge amount of off-gridders, and depending on how someone defines off-gridding it could be even more.
About twice as many people (half million) are homeless: foraging/living in the forest/park/dumpster diving. Maybe there is some overlap?

How about farmers with a well, septic system, maybe a few
solar panels for electricty, and they grow their own food. They usually don't count as off-gridder. But to me they are? How about ranchers, they do the same and I assume they have
alot more practice with a gun. To me that also qualifies as an off-gridder?
If an off-gridder buys fossil fuel and drives to work everyday do they count as an off-gridder?
If an off-gridder buys fossil fuel and uses it to cook/heat and make electricty and also buys his daily food/clothes/electronic/etc does that still count as off-gridding.
I guess
the answer is that it really just depends, its like asking if an apartment renter is a
permie, or if a suburbanite is a permie. In the end it isn't a competition with others. Its all about getting better/improving year after year.
