Data format: Coverage

File or table name: census_2000

Theme keywords: society, boundaries, Census, population, demographics, Census Block

Abstract: Census 2000 geography rectified to Napa County Parcel data (updated October, 2001). This coverage contains population information by Census Block developed by the US Dept of the Census and amended by VESTRA where Census Blocks were split during redistricting for Supervisorial and school Districts.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog.

Description:
Abstract:
Census 2000 geography rectified to Napa County Parcel data (updated October, 2001).  This coverage contains population information by Census Block developed by the US Dept of the Census and amended by VESTRA where Census Blocks were split during redistricting for Supervisorial and school Districts.

Purpose:
For County use in determining population statistics

Supplemental information:
Where census block lines were determined from features such as streams, roads, or public land survey not contained in County parcel data, USGS 1:24,000 quad maps or California Geographic Data Library lines were used.
