Household Income Percentiles for 2000 to 2012

I recently talked about a survey of Americans asking who felt they were in the middle class vs lower or upper classes.   There has been a large increase in the percent of us who think that we're in the lower class.   I wondered if incomes have plummeted for a large portion of Americans or if this was more of a perception thing.

I found detail on household incomes for each fifth at the Census. 

H1 table - Income Limits for Each Fifth and Top 5 Percent of Households

Here's what it looks like from 2000 to 2012 :

Thats not too bad looking but now lets look at it in real dollars:

That doesn't look so good.   Incomes are down from 2000 in real dollars in every fifth as well as the top 5%.

Its hard to see detail on the bottom 3 fifth groups given the scale so I'll show those groups separately: 

There you can see more clearly the drop of real incomes for the bottom 60% of people.
