If you're in the US, you really don't have to look hard.
More than 10% of the population live below the official poverty line, which is
low. For children, the poverty rate is >16%. For a single person with no children, aged 65 or less, the US poverty rate for 2021 was $14100. For a family of four, with two children below the age of 18, the poverty rate is $27500. And so on. And more than 10% of the population live below this threshold.
A lot of these people go hungry a lot of the time. For a lot of kids, school lunches are the most nutritious meal they get in a day.
