The numbers have bounced around a bit, but it's been fairly consistent that ~20% of people marked themselves as having grown up starvation-level poor, which should not be true in a poll that's representative of the U.S., let alone one of a population of people on Mastodon who are mostly programmers.
In surveys, you'll see 20% of some disadvantaged populations with some food insecurity, but that's less a lower level of poverty than this poll's definition of regular starvation or equivalent.
