In the second half of the 20th century, enrollment in U.S. public schools nearly doubled. There was some slowdown during desegregation as enrollment in private schools surged. However, growth resumed by the early 1980s at a little less than 2 percent each year. But by the late 1990s, the growth rate began to noticeably slow, eventually falling to under 0.5 percent annually. Public school enrollment peaked in 2019 at 50.8 million.
During the COVID-19 pandemic, parents pulled about 1.5 million children out of public schools. For the most part, those children do not appear to have returned. The National Center for Education Statistics now estimates that public school enrollment will fall by the end of this decade to a little less than 47 million.
It is important to note that the official public school enrollment numbers include charter schools, which have grown over the past 20 years to nearly 5 million from 1 million. If you subtract the charter school students, enrollment in traditional public schools peaked in 2012 and has since declined by 5 percent.
There are several factors affecting public school enrollment. First, as I have previously noted, women everywhere in the world, but particularly in the United States, are having fewer children. The Census Bureau recently reported that the current fertility rate (children per woman in her lifetime) has dropped to 1.76. A rate of about 2.1 is necessary to maintain a stable population.
As a result, the 63.7 million school-age children today are only slightly more than in 2010. The Census Bureau currently projects that the number of school-age children will decline by 6 percent to 59.9 million by 2050. The reality is that absent allowing a large increase in immigration, the United States will never have more school-age children than it does today.
The second factor is the rapid growth in homeschooling. Over the past two decades, the number of children being homeschooled has tripled from 1 million to 3 million. That has moved the percentage of children being homeschooled from 2 percent to 5 percent.
One of the barriers to homeschooling was the lack of extracurricular activities, especially athletics. However, there has been a large-scale movement to organize such activities within the homeschooling communities, which appears to be quite successful.
Charter schools and homeschooling have combined to drop the percentage of children enrolled in traditional public schools from 84 percent 20 years ago to 78 percent today. The drop would have been more precipitous had it not been for the fact that private and parochial schools have both been losing enrollment even faster than public schools. Parochial school enrollment has fallen by 40 percent and enrollment in private schools by 25 percent. It appears that charter schools and homeschooling may hurt parochial and private school enrollments as much as, if not more than, they decrease public school enrollment.
There are several important takeaways from these data.
First, we should use it to inform our investments in educational facilities. The truth is we do not need any more schools, at least in the aggregate, than we have today. In fact, we should probably already be closing some schools. Certainly, there will be localities where there is still growth and that will need to build some new schools. The exodus from cities to the suburbs and exurbs is an example. But even in those areas, the demographic reality will quickly eliminate the need for any more expansion.
The data on which both the CIS and the Pew Foundation relied mostly predated the recent surge of border crossings. However, even the most recent data on total enrollment are still not showing any increase. It is probably fair to infer from these data that if it were not for the surge in immigration, public school enrollment would be even more sharply declining.
The effect of the ongoing demographic sea change on public education is just one of a myriad of other social, economic, and political systems that are going to be upended by it. We are seeing this first in public education because the drop in birth rates most immediately affects younger generations. However, expect to see more and more manifestations of this demographic sea change through which we are living.
