Claritas demographic estimates are primarily based on U.S. Census and American Community Survey (ACS) data. Claritas uses proprietary formulas and methodologies to calculate estimates for the current calendar year and five-year projections for every annual data release. Claritas warns to not compare estimates between their yearly releases due to changing methodologies and input data used between each data release.
