Answer:
a decrease in the number of college age people because of the low birthrate.
Step-by-step explanation:
In Japan, reticence to marry or have kids has quite likely resulted, at least partly, in a reduction in job prospects for young people. Throughout 1960, 97% of people between the ages of 25 and 29 were working, however by 2010 this figure had fallen to 86%.
Due to such conditions in the past, the level of young individuals have decreased over time leading to decreasing college spots.
