Enrollment in school districts has risen and fallen with the population trends of the areas they serve. The population increase brought about by the “baby boom echo” in the 1980s and 1990s was reflected in a nationwide enrollment increase in public schools. Individual districts have seen their numbers ebb and flow depending on the specific conditions facing them.

But some districts have experienced enrollment growth year in and year out. Of the 100 largest districts, 14 have reported enrollment growth every year since 1986-87 (when the NCES historical database of district enrollment data begins).
