The components of personal income in Idaho have changed since 1979 and the three recessions over the next seven years. Wages and business profits accounted for more than two-thirds of personal income in 1979. Today they combine for almost 55 percent.
Filling that void have been government transfer payments, primarily Social Security and Medicare, which rose less than 11 percent to more than 18 percent over the past 35 years.
Investment earnings have remained relatively constant at around 20 percent.
