Program (see Chapters 6 and 71; or other evaluations and experiments by the Census Bureau (see National Research Council, l999b, 2000a)

Program, in which local and tribal governments reviewed the address lists for their areas;3 block canvass, a field operation to check the entire list, which was not part of the original plans; and a new construction LUCA Program added in response to 2 The Census Bureau refers to the version of the MAF that was used in the census as the Decennial Master Address File or DMAF. It is an extract of the full MAF, which includes business as well as residential addresses.

Unduplication and Late Additions An unanticipated complication arose from evaluations of MAF betweenJanuary and June 2000. These evaluations, which compared MAF housing unit counts to estimates prepared from such sources as building permits, led the Census Bureau to conclude that there were probably still a sizable number of duplicate housing unit addresses on the MAF despite prior computer checks.

These changes include rising numbers of new immigrants, both those who are legally in the country and those who are not, who may be less willing to fill out a census form or who may not be able to complete a form because of language difficulties; increasing amounts of junk mail, which may increase the likelihood that a household will discard its census form without opening it; and larger numbers of households with multiple residences, making it unclear which form they should mail back.6 The Bureau's challenge was to forestall a further decline in mail response and, if possible, increase it above the level achieved in 1990. Approaches to boost mail response in 2000 included four major activities: 4The reinstated people are often called "late additions."

In addition to the ad campaign, the Census Bureau hired partnership and outreach specialists in local census offices, who worked with community and public interest groups to develop special initiatives to encourage participation in the census.

Important innovations for 2000 included the use of outside vendors for major data processing components; the use of optical mark and character recognition technology for data capture; and greater reliance on computer routines to supply missing information, in place of field checks. The challenge for each phase of data processing was to keep on schedule, follow procedures carefully, and minimize last-minute revisions to planned procedures that could affect quality.

Such duplication could occur, for example, when a respondent mailed back a census form after the cutoff date for determining the NRFU workload and the enumerator then obtained a second form from the household. In all, 9 percent of census housing units had two returns and 0.4 percent had three or more returns.
