> Based on these estimates, the observed 2 percentage point decline in the U.S unemployment rate between 1991 and 2001 can explain an estimated 2 percent decline in property crime (out of an observed drop of almost 30 percent), but no change in violent crime or homicide. The sharp increases in crime in the 1960s—a decade of strong economic growth—further corroborate the weak link between macroeconomics and crime.
Violent crime rates started trending up in the 1960s, more than doubling by 1971: https://lh3.googleusercontent.com/U0YlrTTCYi550Z4py1MNVenNt-...
Meanwhile, the economy was quite strong until 1969, with unemployment below 4%: https://fas.org/sgp/crs/misc/RL33069.pdf (p. 5). Poverty rates went down about 40% from 1960-1970, and then were stable until about 1980. Over that same period, violent crime tripled. From 1982 to 1990, poverty went down by 15% and unemployment dropped in half, but violent crime increased 36% to historical peaks.
