SOUTHSIDE ALTER CTR

Public K–12 / combined
SAN ANTONIO, TX · SOUTHSIDE ISD · 72.7% free/reduced lunch

Enrollment trend & projection

Total enrollment + grade 12, NCES Common Core of Data (2021–2024).

If the recent trend holds…

At its recent rate of -1.5%/year, projecting from 2024's 22 students:

2025
22
2027
21
2029
20

≈ 2 fewer students by 2029 — a real revenue/relevance risk worth getting ahead of.

An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.

Revenue at risk

At $15,137 per student in district revenue, the 2 students projected to be lost by 2029 represent ≈ $30,274/year in funding at risk.

District total revenue ÷ enrollment, NCES F-33. Public funding largely follows enrollment, so a shrinking class is a recurring budget hit.
