Synthetic Data
  • When a small-area data set looks too good to be true, it probably is.
    • Health status indicators from BRFSS
    • Commuting data from On the Map (LED/LEHD)
    • Air quality indicators
  • Requires a judgment call on when to use and how to document
survey based data
Survey-Based Data
  • Many small area data sets from Census Bureau are survey-based and are published with MOE values.
    • ACS
    • SAIPE
    • SAHIE

alternative data providers
Alternative Data Providers?
  • Reality check
    • Most private sector providers are using data from the same Federal sources we are.
    • If they’re not, assume the worst about data quality (non-representative samples, unknown methods & motives).
    • State agency data collection fulfills administrative needs, not data analysis needs.
    • State agencies face budgetary and political constraints, too.
  • My philosophy
    • Accept our reality
    • Don’t apologize, EDUCATE!!!
