Her209, the numbers are right there on table a-2, page 26
Income share
Bottom 20% 4.2%
Next 20% 9.2%
middle 20% 14.2%
next 20% 20%
top 20% 52.4%
Now I am not sure what your point is... that the rich make to much? Ok... how do we fix that problem?
We can increase the amount of taxes that they pay, but that won't change the fact that they make more than the poor.
Dahunan These numbers are based on 'households' so it is hard to calculate things like average number of kids etc.
Now it does say that all fifths contain an equal number of people, not an equal number of households. That means for every person living at $14,900 per year there is another person living at 182,700 per year.
Now what is interesting about this fact is that the group with the smallest number of households and therefore the group with the most people per household is not the bottom 20%, but the next 20%, which as a group earns on average 34,200 per year.
The groups with the least people per household would be the richest and the poorest, which makes sense since many of the 'rich' are going to be older people with no kids and many of the 'poor' are going to be single students and the like.
