If you thought your niece’s high school graduation ran a little long last weekend, if you had to show up 30 minutes early to get three seats together at your son’s graduation, or if you had to park three blocks away, there’s good news for you: Future graduations will be less crowded — statistically speaking.

This year’s high school graduating class in the United States was the largest in history, and it may hold that record until the end of the Republic. After next year, the number of American school kids finishing high school will go down basically every year for the foreseeable future.
