Metrics
Metrics Table
The Metrics (or “Master”) table contains raw and derived demographic values at the geography level, including population totals, income figures, and education counts. These are unnormalized values often used as the starting point for analysis.
📌 Note: The Metrics table always includes all geographic columns such as
StateFIPS
,CountyName
,TractFIPS
,ZipCode
, etc., so you don’t need to join separately to access names or locations.
Use when:
- You want to build your own ratios, comparisons, or metrics.
- You need absolute counts (e.g., total households, number of children under 5).
- You're preparing features for machine learning models that require raw data.
- You plan to calculate custom benchmarks or re-aggregate to larger areas.
Table Linking
All three tables — Metrics
, Percentages
, and Percentiles
— can be joined using a shared primary key depending on the geography level:
- BlockGroupID for block group-level data
- StateCountyTractID for tracts
- ZipCode for ZIP-level data
- StateCountyID for counties
- MSA_ID for metro areas
- StateFIPS for state-level data
This makes it easy to pull in raw values, normalized percentages, and national percentiles side-by-side in your analysis or app.
