In the second half of the twentieth 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% each year. But by the late 1990s, the growth rate began to noticeably slow, eventually falling to under .5% annually. Public school enrollment peaked in 2019 at 50.8 million. 

During the 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 (NCES) now estimates that public school enrollment will fall by the end of this decade to just under 47 million.

It is important to note that the official public school enrollment numbers include charter schools, which have grown over the last twenty years from one million to nearly five million. If you subtract the charter school students, enrollment in traditional public schools peaked in 2012 and has since declined by 5%.

There are several factors affecting public school enrollment. First, as I have previously noted, women everywhere in the world, but particularly in the U.S., 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 is only slightly higher than it was in 2010. The U.S. Census Bureau currently projects that the number of school-age children will decline by 6% to 59.9 million by 2050. The reality is that, absent allowing a large increase in immigration, the U.S. will never have more school-age children than it does today.

The second factor is the rapid growth in homeschooling. Over the last two decades, the number of children being homeschooled has tripled from one million to three million. That has moved the percentage of children being homeschooled from 2% to 5%.

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% twenty years ago to 78% 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 enrollment has fallen by 40% and private schools by 25%. It appears that charter schools and homeschooling may hurt parochial and private school enrollment as much, if not more, than public school enrollment.

There are several important takeaways from this data.

First, we should use it to inform our investments in education 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 which will need to build some new schools. The exodus out of cities to the suburbs and exurbs is an example. But even in those areas, this demographic reality is going to quickly eliminate the need for any more expansion.

Second, the stagnant enrollments are certainly inconsistent with the immigration hawks’ narrative that children of illegal immigrants are flooding our public schools. In a 2023 report, based on 2021 data, the Center for Immigration Studies estimated that there were about 3.2 million children enrolled in a public school who have at least one parent that is in the country illegally. However, in many cases, the other parent is a U.S. citizen, and a 2014 Pew Foundation study concluded that about three-fourths of these children had been born in the U.S. and were, therefore, U.S. citizens.

The data on which both the CIS and the Pew Foundation relied, mostly pre-dated the recent surge of border crossings. However, even the most recent data on total enrollment is still not showing any increase. It is probably fair to infer from this 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.

Note – In doing this research, I found that school enrollment statistics are much less exact than I expected. The reporting of enrollment does not appear to be very rigorous. Also, the enrollment changes throughout the school year, and so the counts can vary significantly depending on when the count is taken. There are also various incentives to overcount enrollment. For the purposes of this post, I have relied primarily on the National Center for Education Statistics and the U.S. Census Bureau statistics. I also used Microsoft’s AI, Co-Pilot, to assemble some tables for comparison. While there are some relatively small differences in the numbers reported, the differences are not significantly relative to the overall trend line.
