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.
