A good friend of mine used an outhouse as a kid, she's 34.
Her father is a bit crazy though, he flipped his shit after their mom died (understandable), and moved the entire family to a super remote corner of Aroostook County, northern Maine (less understandable).
They had running water, but in the kitchen sink only. The drain simply connected to a port in the wall and discharged right outside the wall. That part of the lawn was always soapy and muddy, you just learned to avoid it.
For bathing they would use a big tin tub, partially filled with water warmed on the wood burning stove, then give themselves spong baths. Her siblings used an actual chamber pot for convenience at night, but she refused. Standard procedure for night poops involved waking up another sibling so they could bring the rifle and stand guard while you went.
Wolves and bears were common, occasional mountain lions would be seen killed in the road, and heard at night, but never seen. Apparently bears are very easy to detect because they stink, and wolves are mostly harmless.
This was in the late 1990s, and what's worse the poor girl grew up in a decent neighborhood of Boston before the father went crazy, so she certainly didn't grow up needing a rifle to shit.
They had power, but it was extremely unreliable. They had an ancient oil burning generator for when the power would go out for weeks at a time. On cold nights everyone would just sleep near the woodstove. As for the stove, it was the kind that had oven and cooktop built in (like you see in civil war era reenactments). On a group trip we all went to a historical tour of some preserved late WWI-era house and she was very excited to see the stove was the same model as hers.
Surprisingly they had telephone, and they got one television channel from Canada. She was about 20-30 minutes from a town of 5,000, and a little over an hour from the nearest big town (15,000 people). She said they used to make the 2.5 hour round trip to the "big town" for the extraordinary treat of visiting the only Burger King in an 100 mile radius.
Some parts of America are still wild.
