The USDA’s National Agricultural Statistics Service (NASS) conducts the U.S. Census of Agriculture in years ending in 2 and 7. Population estimates from the census are adjusted for undercoverage, non-response and misclassification and calibrated to known population totals. These adjustments are reflected in weights that are attached to each responding unit. Calculating these weights has been a two-part procedure. First, one calculates initial (Dual System Estimation or DSE) weights that account for under-coverage, non-response and misclassification. and in the second step, calibration is used to adjust the weights by forcing the weighted estimates obtained in the first step to match known population totals. Recently, a calibration algorithm, Integer Calibration
(INCA), was developed to produce integer calibrated weights as required in NASS publications. This paper considers combining the two steps of calculating weights into one. This new algorithm is based on a regularized constrained dual system estimation methodology, which combines capture-recapture and calibration (CaRC).
