Information available at Dimpled Chad is derived from the current population surveys conducted by the U.S. Census Bureau. However, we do not make use of these data in its original form but apply a universal coding scheme to the raw data files so as to permit comparable results over time. As a result, numerous variables, variable categories, and cases appearing in the original data have been excluded, modified or re-named.
