Looking at the census publication directly[0], seems Wikipedia is wrong then.

That's household income, which includes multiple people's income for households in which multiple people work. Median income for individuals was $33,706 in 2018, the last year for which data is available. https://fred.stlouisfed.org/series/MEPAINUSA672N

Now you’re starting to see the problem. Everyone has their way of calculating median and each, while factually correct given the set of parameters, is incompatible for comparison to anything not using the same methods/process.

That $31k figure includes part time workers, who dream drag down the number, and who won't be getting full unemployment anyway. So it's a bad comparison.

The median full time worker in the USA make over $50k a year according to data collected by the BLS

That's for men ($991/week). For women it's about $42k ($796/week)

$1052 for men ($54,808)

$852 for women ($44,304)

Average it out (more men than women in full time workforce) and it's $50k a year or so
