"Census 1990 Block Data provides a seamless statewide GIS layer of census blocks with associated attributes . The data have been "migrated". Large sparsely populated rural census blocks often contain areas of public lands that are typically uninhabited. Migration involves adjusting the population/housing density on these lands to zero and adjusting the population/ density numbers for the habitable land upward so that overall population in the block remains constant. Migration was performed using Teale Data Center Ownership data (GOVTOWN, 1999)"</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Purpose:</I></DT> <PRE ID="original">This data layer was edited from its original source data set for inclusion in the Russian River Watershed Adaptive Management Plan (RRWAMP) and RRWAMP Baseline Watershed Assessment project. The intended use of this data layer in this project is to examine landscape or human factors to promote ecological health and sustainability within the Russian River watershed. "The California Mapping Coordinating Committee identified the need for a single standard statewide source for 1990 census block data. CDF merged the TIGER county files into a single statewide data layer. Also, by taking advantage of GIS data for public land ownership, the migration process yields a more accurate and detailed depiction of spatial demographics, primarily in sparsely populated rural areas."</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> </DL> </DD> <DT><I>Time_Period_of_Content:</I></DT> <DD> <DL> <DT><I>Time_Period_Information:</I></DT> <DD> <DL> <DT><I>Single_Date/Time:</I></DT> <DD> <DL> <DT><I>Calendar_Date:</I> 1990</DT> </DL> </DD> </DL> </DD> <DIV> <DT><I>Currentness_Reference:</I></DT> <PRE ID="original">ground condition</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> </DL> </DD> <DT><I>Status:</I></DT> <DD> <DL> <DT><I>Progress:</I> Planned</DT> <DT><I>Maintenance_and_Update_Frequency:</I> per decade</DT> </DL> </DD> <DT><I>Spatial_Domain:</I></DT> <DD> <DL> <DT><I>Bounding_Coordinates:</I></DT> <DD> <DL> <DT><I>West_Bounding_Coordinate:</I> -123.387866</DT> <DT><I>East_Bounding_Coordinate:</I> -122.522658</DT> <DT><I>North_Bounding_Coordinate:</I> 39.399217</DT> <DT><I>South_Bounding_Coordinate:</I> 38.298024</DT> </DL> </DD> </DL> </DD> <DT><I>Keywords:</I></DT> <DD> <DL> <DT><I>Theme:</I></DT> <DD> <DL> <DT><I>Theme_Keyword_Thesaurus:</I> none</DT> <DT><I>Theme_Keyword:</I> watershed management</DT> <DT><I>Theme_Keyword:</I> environment</DT> <DT><I>Theme_Keyword:</I> Demographics</DT> <DT><I>Theme_Keyword:</I> Census</DT> </DL> </DD> <DT><I>Place:</I></DT> <DD> <DL> <DT><I>Place_Keyword:</I> Russian River</DT> <DT><I>Place_Keyword:</I> Sonoma County</DT> <DT><I>Place_Keyword:</I> Mendocino County</DT> </DL> </DD> </DL> </DD> <DT><I>Access_Constraints:</I> none</DT> <DIV> <DT><I>Use_Constraints:</I></DT> <PRE ID="original">The user assumes the entire risk related to the use of this data.

is distributed by county. The county boundaries do not match USGS county linework and in some cases overlap adjacent counties at their edges. CDF-FRAP cleaned these slivers arbitrarily and therefore the county boundaries may not match boundaries of the original TIGER files. Calculate population and housing counts using POP100_DENS and HU100_DENS, respectively. Create two new numeric fields called PEOPLE and H0USES. Setting data type to Double with Precision = 12 and Scale = 6 will minimize rounding error when data are summarized. Example: [PEOPLE] = [POP100_DENS] * [AREA] * .0000003861003 Assuming AREA is in square meters, this formula calculates number of people by multiplying population density (per sq mile) by square miles. Because AREA will change if new polygons are created by clipping or overlays, AREA must be recalculated (XTools are convenient) followed by PEOPLE and HOUSES. Housing and population summaries for entire counties may be slightly different than the official census count because of differences in TIGER and USGS county linework as noted above. POP100 and HU100 values are *not* to be used for summary purposes because they are specific to whole blocks and were carried over from the raw census data prior to the overlay that determined uninhabitable areas and split some blocks into multiple polygons.

This key can be used to link other attributes from the 1990 Census STF1 data files to the block geography. FIELD NAME: UNINHAB Public lands from GOVTOWN that generally do not contain public habitation or developed areas. These areas were excluded from calculation of HAB_SQ_MILES. CDF_FRAP considered the following public ownership classes 'habitable' and therefore did not exclude census counts. Although large portions of some of these ownerships may indeed be uninhabitable (such as DoD lands), no such delineations exist and large numbers of people do reside on these lands. In contrast, although people do reside in National Parks (such as Yosemite Valley), these numbers are small and the vast majority of the NPS lands are uninhabited.
