The median household income is the income of the household who happen to land on the 50% line of all the household incomes, that is to say, they don't have a 50% income of what the richest have, they are the ones who if you are counting households from richest to poorest, are the exact middle number, not the middle income. That's obvious if you know what median means, otherwise not clear at all.
... what does that mean ??? ...
According to wiki .. 'The median is the value separating the higher half from the lower half of a data sample' .. so if 1 is the least and 10 is the max the median is 5, but if 1 is the min and 9 is the max the median is (4+5)/2 = 4.5 ...
Anyway I think has to be seen if the data set is contiguous and/or has gaps or such.
And then again if you have 1000 houses with income 10 and 10 houses with income 500 I am still not sure "how you evaluate that". (*)
I am guessing "a single value is not enough", you should look at a histogram.
(*) I THINK the median could be still in the range of 400 ( if all values are continuous ) but the reality is the majority of people have 10 not 400.
