Unemployment 2024 (all geographies, statewide)

These data were developed by the Research & Innovation group at the Atlanta Regional Commission using data from the U.S. Census Bureau across all standard and custom geographies statewide where applicable. For a deep dive into the data model including every specific metric, see the ACS 2020-2024 Data Manifest. The manifest details ARC-defined naming conventions, field names/descriptions and topics, summary levels; source tables; notes and so forth for all metrics.

Therefore, any measure reported by ACS should not be taken as an exact number – this is why a corresponding margin of error (MOE) is also given for ACS measures. The size of the MOE relative to its corresponding estimate value provides an indication of confidence in the accuracy of each estimate. Each MOE is expressed in the same units as its corresponding measure; for example, if the estimate value is expressed as a number, then its MOE will also be a number; if the estimate value is expressed as a percent, then its MOE will also be a percent. The user should also note that for relatively small geographic areas, such as census tracts, ACS only releases combined 5-year estimates, meaning these estimates represent rolling averages of survey results that were collected over a 5-year span (in this case 2020-2024). Therefore, these data do not represent any one specific point in time or even one specific year. Change analysis within a five year time series or between overlapping time series years should not be performed. ARC has prepared change datasets as shown on the ARC Census Data Directory.
