The following are block level data files with selected variables. The Arizona file contains all blocks in the State of Arizona. The county files contain blocks of their respective counties. Please note that because of the Census Bureau’s implementation of Differential Privacy (DP) for its Disclosure Avoidance System (DAS), data at the block level can be very noisy. They should not be used on their own. They need to be aggregated to higher geographies such as block groups and census tracts to yield meaningful data.
