The Bay Area Consumer Price Index

I ran into some interesting data posted by Association of Bay Area Goverments (ABAG).    The data in question is the “Bay Area Consumer Price Index”.

The Consumer Price Index (CPI) measures the change in the price of goods over time. The change in the index is referred to as the rate of inflation. The numbers presented here are distributed by the Bureau of Labor Statistics (BLS) for the Consolidated Metropolitan Statistical Area (CMSA) covering San Francisco – Oakland – San Jose. This series is generally used as representative of the CPI for the nine-county bay region.

I moved to California in 1996, so I took that as a base and calculated the % change in CPI year-over-year or the rate of inflation.

In the last column, I convey the fact that if I had $100 in 1996 and I had not earned interest on it, it will be worth only $68.71 in today’s money (or, roughly 31% less).
