If you take the lowest number income to the highest and put them in

Correct.

Average is the total income of all the households divided by the
number of households. One family making $500,000,000 against several
million in the $40,000 range would have little effect on the average
and a big hit on median.

Nope. If you had two families making $20,000, one making $40,000, and two making
$80,000, the median would be $40,000 and the average would be $48,000. If one of
those top-earners gets a raise to $100,000, the median is still $40,000, but the
average goes up to $52,000.
