Size changed directionally at one school over 2013–2023; the peer's series stays a range. Pair any selectivity note with that asymmetry before treating the two campuses as parallel growth stories.

College Scorecard institution series; dollars are nominal. Direction claims require r² ≥ 0.40 on the fitted annual slope, otherwise the page reports the observed range. Descriptive history, not a recommendation.
