7% in 1980 to 11% in 1982, then declined to 5% in 1988. The inflation rate declined from 10% in 1980 to 4% in 1988. Some economists have stated that Reagan's policies were an important part of bringing about the third longest peacetime economic expansion in U.S. history. During the Reagan administration, real GDP growth averaged 3.5%, compared to 2.9% during the preceding eight years. The annual average unemployment rate declined by 1.7 percentage points, from 7.2% in 1980 to 5.5% in 1988, after it had increased by 1.6 percentage points over the preceding eight years. Nonfarm employment increased by 16.1 million during Reagan's presidency, compared to 15.4 million during the preceding eight years, while manufacturing employment declined by 582,000 after rising 363,000 during the preceding eight years. Reagan's administration is the only one not to have raised the minimum wage. The inflation rate, 13.5% in 1980, fell to 4.1% in 1988, in part because the Federal Reserve increased interest rates (prime rate peaking at 20.5% in August 1981). The latter contributed to a recession from July 1981 to November 1982 during which unemployment rose to 9.7% and GDP fell by 1.9%. Additionally, income growth slowed for middle- and lower-class (2.4% to 1.8%) and rose for the upper-class (2.2% to 4.83%). The misery index, defined as the inflation rate added to the unemployment rate, shrank from 19.33 when he began his administration to 9.72 when he left, the greatest improvement record for a President since Harry S. Truman left office. In terms of American households, the percentage of total households making less than $10,000 a year (in real 2007 dollars) shrank from 8.8% in 1980 to 8.3% in 1988 while the percentage of households making over $75,000 went from 20.2% to 25.7% during that period, both signs of progress. Employment The job growth (measured for non-farm payrolls) under the Reagan administration averaged 168,000 per month, versus 216,000 for Carter, 55,000 for H.W. Bush, and 239,000 for Clinton. Measuring the number of jobs created per month is limited for longer time periods as the population grows. To address this, we can measure annual job growth percentages, comparing the beginning and ending number of jobs during their time in office to determine an annual growth rate. Jobs grew by 2.0% annually under Reagan, versus 3.1% under Carter, 0.6% under H.W. Bush, and 2.4% under Clinton. The unemployment rate averaged 7.5% under Reagan,
