UNI-CEN Standardized Census Data Tables contain all publicly disseminated data tables for five commonly used levels of geography. The source data have been modified to standardize the table layout. Variable codes and names have been standardized across time. Where variables are organized hierarchically, whereby counts sum to subtotals and totals, the hierarchy is made explicit.
