# Optional policy-track recipes

Run these scripts from the Math Camp project root after completing the shared
health example.

| Script | Unit and sample | Main comparison |
|---|---|---|
| `01-health.R` | Complete country-years, 2000–2022 | Log income and under-five mortality |
| `02-gender.R` | Complete country observations in 2022 | Female secondary enrollment and adolescent fertility |
| `03-access.R` | Countries with at least ten years between first and last complete observations | Annual change in electricity and internet access |
| `04-climate.R` | Complete country observations in the latest common year | Renewable electricity, carbon intensity, and growth |

Each script defines the sample required by its question, checks its key, creates a
figure, and writes an evidence receipt to `outputs/`.
