According to Thomas Klitgaard and Preston Mui of the NY Fed’s Liberty Street Economics, Japan’s population is both shrinking and getting older, with the population falling at a 0.2% rate in 2014 and the working-age population (ages 16 to 64) plummeting at the rate of almost 1.5% a year. Contrast this with the U.S. population, which is is rising at a 0.7% a year with the working-age population increasing at a 0.2% rate.
