Data

The sources I've worked with, at every level of government, plus research datasets and data I've collected myself. Knowing where Texas data comes from, how it's built, and what it can't tell you is half of good analysis.

Geographies I work across

Much of my analysis is about what changes when the same data is aggregated to a different boundary. These are the units I've built data at, from smallest to largest.

  • Census block
  • Block group
  • Tract
  • Voting precinct
  • Justice precinct
  • ZIP area
  • City and ETJ
  • School district
  • County
  • Legislative district
  • ESC region
  • MPO region
  • Metro area
  • State
