Methods for Integrating Multiple Data Sources to Improve Crop Estimates

Project Scope

An ad hoc panel is working to review, assess, and make recommendations on methods for integrating multiple data sources to improve county-level crop estimates produced by the National Agricultural Statistics Service (NASS) of the U.S. Department of Agriculture. The goal of the project is to provide more precise estimates with appropriate measures of uncertainty for current county-level estimates of acreage, yield, and cash rents for major crops. Multiple sources of data are potentially available for county-level crop estimates, including NASS surveys, data from other agencies, and automated field-level information collected by farm equipment dealers. The panel is working to explore methods for combining the information from these and other sources to produce more precise county-level estimates with valid measures of uncertainty. Issues to consider include the methods used to integrate the information, the assumptions underpinning each approach, the robustness of the estimates to a failure of one or more assumptions, and other technical issues. In addition, the panel will consider the suitability of using each data source and the properties of desirable estimates of uncertainty. The panel will produce a final report with findings and recommendations at the conclusion of the study.
