My dad grew up with hand-pump well water, an outhouse, a four-room house his dad built on cinderblocks that was too small for both the girls and the boys so the boys slept in the barn (and I think maybe they had a dirt-floor house at first, that one may have come after he was born), no electricity in his early years, no phone until he was a teen and I think it was a party line until after he moved out. Pretty sure they still had a one-room school house, too (small rural town).

This was the late '40s through '60s, not even the '30s. In the US.
