'The September Consumer Price Index, which measures inflation, increased 0.3% from last month. Food increased 0.4% and energy 2.0%. Gas alone increased 2.9% in a month and food at home, or groceries, increased 0.6%. Core CPI, or price increases minus food and energy costs, rose 0.1%. Core CPI is a Federal Reserve inflation watch number. For the year, not seasonally adjusted, the Consumer Price Index for all Urban Consumers (CPI-U) has risen 3.9%. In August CPI also increased by 0.4%.' http://www.economicpopulist.org/content/cpi-03-september-2011 BTW - that is the highest inflation rate in 3 years and the third highest September inflation rate in over 20 years (since 1990). That's higher then all but 2 of the housing boom years and higher then ALL of the dot.com boom years. http://www.usinflationcalculator.com/inflation/historical-inflation-rates/
