How is the Personal Savings Rate chart from the last entry to be interpreted?

Question: This chart can have several interpretations. Is the increase in savings a true increase, or being a
percentage, is it only indicating a decrease in disposable income? Hmm? Here’s an attempt to answer:

Per Capita Personal Income                                                                                                                                                       

Area/Name        2000       2001       2002       2003       2004       2005       2006       2007       2008       2009       2010P

United States    30,318   31,145   31,462   32,271   33,881   35,424   37,698   39,392   40,166   39,138   40,584

I don’t know how the experts figure it, but by my calculations, real income, adjusted for inflation, increased 2% in 2009. So at least it seems to be a positive number. But I’ll check some more.

CALCULATIONS: PCPI increased from 2009 to 2010 = 3.7%, but the Consumer Price Index 2009 – 2010 was 214.537 – 218.056. So the 2009 inflation was 218.056/ 214.537 = 1.0164 of 1.6%. So 2010 expressed in 2009 prices is 40,584/ 1.0164 = 39,929. And 39,929/ 39,138 = 1.020%.
