The Western Interstate Commission for Higher Education's (WICHE's) ninth edition of "Knocking at the College Door: Projections of High School Graduates," published in December 2016 (revised February 2017), quantified how the demographic changes that are underway with America's youth population will be evidenced in the next 15 years of high school graduates. The purpose of this brief is to present universal trends and the variation within, with a focus on the WICHE West states. Across the nation, graduating classes are projected to gradually become smaller at the same time that they become even more diverse. While the national projections describe universal trends, there is variation among the four geographical regions and states. In some states, primarily in the South and West, robust increases are projected for the number of graduates overall and the overwhelming majority of these will be non-White and primarily Hispanic. Where increases are projected, they will peak around 2025. In states with projected growth, the number of high school graduates is expected to decrease by as much as 8 percent into the early 2030s. The West is projected to have modest growth in the number of high school graduates through 2024, and then the number will rapidly contract, driven by declines in Hispanic high school graduates.
