Elementary school enrollment (grades 1 through 8) declined from 32.2 million students in 1972 to 31.5 million in the fall of 1973. This decline in elementary school enrollment which started in 1970-71 reflects a decrease in the number of persons of elementary school age in recent years as the children born in the mid-1960' s replaced those born in the high fertility period of the 1950's. The number of births in the United States began to decline in the early 1960' s and elementary school enrollment declined after 1970 as those children reached school age. The decline occurred in both private and public schools. Private elementary enrollment has declined by 1,578,000 students since 1964, to a current level of 3.3 million. Public elementary enrollment declined by about 500,000 in the past year to 28.2 million students (returning to the same level as in 1966 ). High school and college enrollment levels for persons under 35 years old have not changed significantly during the past 2 years; about 15.3 million students attended high school (grades 9 through 12) and 8.2 million persons 14 to 34 years old attended college. The number of persons in these ages are still unaffected by the declining trend in fertility.
