Descriptive nameCensus Blocks - 2000 (adjusted)

Abstract2000 Census Block boundaries that have been adjusted to streets and parcel boundaries, where possible. Census Blocks are the smallest unit used by the U.S. Census
Bureau for demographic tabulation. See more information.
Known errors/qualificationsThe name cen2001b is a bit of a misnomer. The "1" indicates the rectified derivative of the unadjusted Block boundaries in the layer cen2000b. Currently, cen2001b contains only population and ethinicity information. The abstract's "more information" link includes the data dictionary for population and ethnicity fields.
