Stable inputs
SourceData/ is the stable input layer for replication. It includes source CSVs, census geography files, setup notebooks, and utility code used to harmonize the different SVI sources.
Source families
- CDC ATSDR: tract-level social vulnerability source files for Texas and the United States.
- HRRC / Texas Planning Atlas: regional tract and block-group vulnerability files for Texas.
- UT Preisser / SVInsight: academic SVI setup files and exports used for comparison.
- Census geography: supporting TIGER/Line geometry used in geographic analysis and mapping.
What should not change during replication
- Raw files in SourceData/ should remain fixed.
- Replication notebooks in Posted/ should be rerun, not casually overwritten.
- Intermediate and exploratory output should go to Work/, which is ignored by Git.
Large-file note
Some raw inputs are large enough to trigger GitHub warnings. Keep that in mind if you add more shapefiles or full national extracts; for future growth, consider Git LFS or external download instructions.
