The Update Enumerate operation assigned enumerators to interview and update addresses in selected rural areas. These interviews were completed on paper questionnaires and collected information on housing unit status, population count at the address, and demographic data about the people living at the housing unit. All completed questionnaires were returned to the Local Census Office for check-in and subsequently shipped to a data capture center. The Update Enumerate quality assurance program ensured the Update Enumerate enumerators understood and followed interviewing and listing procedures through enumerator observations, a separate reinterview operation of enumerators to detect and deter falsification, a Dependent Quality Control Check of production listing work, and through Delete Verification. A Final Delete Verification was also conducted to verify addresses deleted for the first time by a quality control enumerator.
