Two measure of Alternative CPI are included for the period of 2001 – 2011. This period was considered important largely due to the US housing bubble and the failure of the conventional CPI measure to detect the resulting inflation. Both measures below utilize Case-Shiller housing price data to calculate “Alternative CPI”. #1-A uses Case-Shiller’s 10-City price index while #1-B utilizes Case-Shiller’s 20-City price index. The third chart compares the two results and shows only minor differences over time, which has led us to focus more on the longer-running 10-city index.
