With the development of new statistical techniques, computing technology, and increasing availability of data, data accuracy presents a new challenge—privacy—that is in direct opposition with the goals of accuracy. Throughout its history, the Census Bureau (or those authorized to carry out its mandate) has essayed to collect and report accurate data; meanwhile the call to protect the privacy of respondents has grown. The opposing goals of accuracy and privacy have led the Census toward a new disclosure avoidance method—differential privacy—that aims to protect privacy and provide reasonably accurate data to users. This change signals a new phase of disclosure avoidance and data reporting at the U.S. Census Bureau. Indeed, this may be the beginning of a new world of privatized data in general.
