I thought it would be interesting to see the breakdown of American net worth statistics by the different geographic regions. A couple overall trends stand out.
The southern region of the U.S. has always had the lowest net worth according to these statistics, and the northeast and west has increased most significantly since 2001. The American midwest pretty much barely changes at all, strange. I guess their overall net worth can be considered very steady overall, no extreme highs but no lows.
I am assuming much of the overall net worth increase after 2001 is due to rapidly increasing housing values from the housing boom. The northeast median net worth increased 62 percent between 2001 and 2004. This number is so high I can hardly believe it, amazing. Same for the American west, net worth increased 50 percent between 2004 and 2007!
Overall I believe with the 2008-2010 housing crash the net worth for the west and northeast areas of the United States will eventually come back in line with the other areas. They say that everything reverts to the long term averages eventually, and I think that will be correct with American net worth statistics also.
