That’s “Household income”. Household income is the most useless and skewed statistic I can think of when it comes to equality and actual income per person.
In my mind rich people can afford to live in different homes. Poor people can not afford to do so. That means if 8 poor people who each make eg 10k a year share a household then their household earns 80k. Now if 8 less-poor people who each make eg 40k a year are split over four households then their households also make 80k each.
So now there’s 4 households of 2 people each that make as much as 1 household of 8 people. Here statistically 100% of households make exactly 40k. Regardless 50% of those 16 people still make less than 35k a year.
In reality people inside one household have different incomes, which means even among the 4 slightly richer households in the example above some inhabitants would probably make less than 35k.
One question I have is how do household-statistics count people who have multiple houses? If a rich person owns 10 houses, then does it count as 10 households who earn >35k? I hope not.
