Data Quality Information:

Attribute accuracy report:
  Attribute data was copied directly from TIGER files and Census Public Law 94-171 redistricting population count databases. The State Library has only spot checked a few block group polygons against the PL 94-171 database, but found no reason to believe that any data was joined incorrectly. It is beyond the scope of this report to discuss the accuracy of the 2000 Census population counts.
Completeness report: Data set is complete
Horizontal Positional Accuracy Report:
  Approximate horizontal accuracy is 51 meters, assuming source data meets National Map Accuracy Standards.

    Title: Public Law 94-171 Files
    Publication place: Washington, DC
    Publisher: U.S. Census Bureau
    Source contribution: This is the source of the population counts.
    Calendar date: 04/01/2000
  Process step:
    The TIGER/Line files were imported into a series of ArcView shapefiles for each Montana County using TGR2SHP version 4.1 by GIS Tools of Knoxville, TN. The individual county shapefiles were converted to Arc/Info coverages, combined into a single data set for the entire state, and converted to State Plane Coordinates.
  Process date: 2001
  Process step:
    A subset of the population count fields from the Public Law 94-171 database was joined to the attribute table for the data.
  Process date: 2001
