Table 3 The difference between the GeoLytics and Claritas population estimates from US Census estimates for 2005 and 2007. Claritas data varied to a greater degree than GeoLytics estimates. Aggregating across all counties to compute statewide totals dampened the overall difference from US Census estimates.
