Another Correlation

Updated: 10/07/15

This graph shows a measure of inequality of income along with a measure of partisan polarization in the U.S. House of Representatives. I would never have thought of this pairing, but Nolan McCarty, Keith T. Poole, and Howard Rosenthal did. (Scroll down after linking.)

Their data set stops at 1998.    Now updated through 2012.

Here is the original graph, through 1998, via the Krugman link below.

Since then, as I originally suspected, it has only gotten worse, on both counts.

Krugman thinks finance sector wages are a cause. Works for me.

More generally, I blame the Republicans.  Really.
