Correction: A Gentler Decline

In a blog post a few days ago, I linked to a map showing declines in median incomes across the U.S. Now I see The Washington Monthly reports a problem with the map.

they used a different measure for the 1999 figures than for the 2005 numbers, and that made the decline look worse than it was.

There is a chart (no map this time) at the Washington Monthly site with more consistent data.

I’ve heard it’s a good practice to correct your errors. Might as well give it a try.
