Figure 3: Inflation and Inflation Expectations
Note: Inflation in the previous year is measured by the percent change in the annual average of the CPI from the level in the previous year. Inflation expectations (1-year ahead) are measured by the one-year expected inflation in GDP prices for the 1976-1995 period, as reported in the first-quarter Survey of Professional Forecasters. For the 1996-2014 period, inflation expectations are measured by the one-year expected inflation in the CPI from the Survey of Professional Forecasters.

Figure 4: Total, Short-term, and Long-term Unemployment
Note: The long-term unemployment rate is defined as those unemployed for more than 26 weeks divided by the civilian noninstitutional population over age 16. The short-term unemployment rate is the total unemployment rate minus the long-term unemployment rate. The shaded regions indicate short- or long-term unemployment contributions to the total unemployment rate, which is the top edge of the shaded region. The data span the period from January 1948 to October 2015.
