Umm -- the definition of median is that half the range is higher and half is
lower. This means that if the median is $42,000, and there are 100 million
households, then 50 million households make more than $42k.

That sounds like an average rather than a median.
If you take the lowest number income to the highest and put them in
order the number in the middle would be the median.

This is correct only if "the number in the middle" means half of the
sequence of numbers are below it and half are above it. Such a
"median" may or may not also be the "mean".
