Total enrollment at Wisconsin's public and charter schools declined by 25,000 students from fall 2019 to fall 2020 and has continued to fall in the years since then. While declining birth rates and apparent movement of some students to private or home schools likely account for at least two thirds of the decline, somewhere between 0.5% and 1.2% of the state's school-age population may be unaccounted for, raising questions about their whereabouts and well-being, the state's workforce, school finances, and more.
