This item should be used to link or join this table to the Census 2000 Block Groups (CEN00BG03_1) region subgroup SPLIT_BG attribute table. FIELD NAME: SUMLEV_090 Unique identifier for the smallest statistical and geographic unit captured by Census for Summary File 3 sampling data. SUMLEV_090 is a concatenation of FIPS STATE CODE + COUNTY FIPS CODE + COUSUB CODE + PLACE CODE + TRACT CODE + UR CODE + BLOCKGROUP CODE. SUMLEV_090 has a one to one relationship with LOGRECNO. FIELD NAME: H034001-H034010, CUML39-CUML00 Historical data come from housing counts in the 2000 U.S. Census of Population and Housing long form survey question "Year Structure Built" (Summary File 3A). Note that if a house was demolished and rebuilt, only the rebuild date is reflected in the data, which means that housing density in earlier decades may be underestimated. For a detailed methodology of CDF-FRAP's projection model see http://frap.cdf.ca.gov/projects/development_vegetation/index.html. The relationship of the original Census SF3 attributes to the calculated attirbutes are as follows. cuml39 = H034010 cuml49 = H034010 + H034009 cuml59 = H034010 + H034009 + H034008 cuml69 = H034010 + H034009 + H034008 + H034007 cuml79 = H034010 + H034009 + H034008 + H034007 + H034006 cuml89 = H034010 + H034009 + H034008 + H034007 + H034006 + H034005 cuml00 = H034010 + H034009 + H034008 + H034007 + H034006 + H034005 + H034004 + H034003 + H034002 DISCLAIMER The State of California and the Department of Forestry and Fire Protection make no representations or warranties regarding the accuracy of data or maps.
