About the Vendor Study
For an unbiased answer to the question of data accuracy, Esri commissioned an independent study:
- Blind study conducted by 4 credentialed researchers, experts in small area forecasts and measures of forecast accuracy
- Data from each of the five major data vendors, including Esri, was benchmarked against results from Census 2010. Identities of the four other vendors will not be revealed.
- Complete study for the entire US at 4 geography levels
The results are in… Esri's Data is #1
This chart illustrates Precision scores for each data vendor by geography. The lowest score indicates the most precise data—the highest accuracy.
