8. **Luo, W., Wang, F.** (2003). *Measures of spatial accessibility to health care in a GIS environment.* Environment and Planning B 30(6): 865-884. Methodological cousin of our gap-ratio computation.

9. **Andersen, R. M., Aday, L. A.** (1978). *Access to medical care in the U.S.: realized and potential.* Medical Care 16: 533-546. Realized vs potential access; our gap-ratio is a potential-access metric.

## VI. Companion paper

26. **Trellison Institute.** (2026, May). *The Mental Health Access Gap in the United States Divides into Two Distinct Problems.* Working paper v1.0. https://trellison.com/research/mental-health-supply-demand-gap. The adult tract-level companion paper. The youth paper inherits the methodology and is the framework's second published application.

## VII. The Need-vs-Access Framework's intellectual lineage

The Need-vs-Access Framework v1.1 sits in the tradition of:

- **The Five A's of Access** (Penchansky & Thomas, 1981) — state-level supply distribution captures the Availability dimension explicitly.
- **Two-step floating catchment area methods** (Khan 1992 / Luo & Wang 2003) — our framework's state-rollup is a degenerate one-step case appropriate for state-level analysis.
- **The Andersen-Aday potential vs realized access framework** (1978) — our gap-ratio is potential access; realized access requires household-level survey data beyond our scope.

The framework's specific contributions for youth-level analysis are: (i) the explicit national OLS regression option for low-N geographies, (ii) the pre-specified dartboard sampling that prevents post-hoc cherry-picking of outlier states, (iii) the integration of state-level YRBSS need with NPPES youth-taxonomy supply in a single residual-regression pipeline, (iv) the open-source DB-native tool implementation supporting both tract and state geography in v1.1.
