Area Migration with Demographics
Area Migration captures the net migration, inflow, and outflow by State, CBSA, County, Tract and ZIP geographies. Median income and age inflows (average) in the area are also included. Demographic data is based on the latest available Census Amercian Community Survey dataset (5-year).

| confidence_score* | FLOAT | Score indicating the degree of confidence | 1.0 | This value indicates the degree of our confidence about the extrapolated number of moves. The higher the value (max is 1.0) the higher our confidence. |
*Confidence score is a planned future update which is included in the schema already to prevent issues for data delivery and integration when it is later implemented. As of now the confidence score is set to 1.0.
