Abstract:
|
The USDA National Agricultural Statistics Service (NASS) conducts the annual Agricultural Resource Management Survey (ARMS). ARMS collects detailed economic data from a sample of US agricultural operations and suffers from relatively low response rates for a federal survey. To compensate for nonresponse bias, coverage and measurement errors, NASS uses calibration weighting in the ARMS. Preliminary research using 2002 Census of Agriculture data, available for 2005 ARMS respondents and nonrespondents, indicated that calibration decreased nonresponse bias. The present study replicates prior research for the 2006 ARMS. The difference between respondents and the full sample was compared for several key survey variables both with and without calibration weights. 2006 results were compared to 2005 showing that calibration continues to be an effective method for reducing nonresponse bias.
