Part 2 (1 point) See Hint Think of the overall unemployment rate as a weighted average of each age group's unemployment rate. The table below reports each age cohort's labor force share (LFS) and unemployment rate for four years. 16-24 25-54 55+ Year Labor force Unemployment rate Labor force Unemployment rate Labor force share (LFS) share (LFS) share (LFS) Unemployment rate 1970 21.6% 11.1% 60.9% 3.4% 17.5% 2.9% 1985 20.5 13.6 66.6 5.9 12.9 4.1 2000 15.8 9.3 71.1 3.1 13.1 2.6 2015 13.5 11.6 64.4 4.5 22.1 3.8 The overall unemployment rate in 1985 was % (give your answer to one decimal place).
