Budgetary political threats

Budgetary/Political Threats

  • Already targeted

    • Bureau of Economic Analysis Local Area Personal Income & Employment

    • Bureau of Labor Statistics special initiatives (e.g. Green Jobs surveys)

Confidential and suppressed data

Confidential and Suppressed Data


Synthetic data

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

  • How much does this matter for our project?

    (clue: A LOT!!!!)

  • How do other data providers handle this issue?

    (clue: DERELICTION OF DUTY)


Acs sample sizes by county type

Implications for our project

Implications for Our Project


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!!!


Poor no acknowledgement of uncertainty in map or text

Poor: No acknowledgement of uncertainty in map or text

What s new in data

Fair: No acknowledgement of uncertainty in map or text, but uses a reference value that allows for significance testing

What s new in data

Good: No acknowledgement of uncertainty in map, but table includes confidence interval values
