  1. The producer's accuracies show, of those defined by the authors as urban/rural, the percentage classified correctly, while the consumer's accuracies show, of those classified as urban/rural by the global map in question, the percentage of surveys classified correctly. The kappa statistic compares agreement between each map and the author-defined definitions against that which may be expected by chance, with values ranging from 1 (perfect agreement) to 0 (no different from chance agreement) to -1 (perfect disagreement).
