Description:

Abstract:

The NC Center for Geographic Information and Analysis, using TIGER/line 2000 files and statistics from the US Department of Commerce/Bureau of the Census, developed the GIS 2000 Census Block data sets for each of the 100 counties in North Carolina and combined the data into one statewide coverage.

Purpose:

This file was developed to enable a user to see the geographic component from the 2000 Census.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The digital files from the Census Bureau were converted into ARC/INFO files. Selected attributes were joined to the TIGER files from the Census 2000 Summary File 1. Each county coverage was checked against county census block grid maps on the Census Bureau website (www.census.gov Maps=>Map Products=>Census2000 block maps=>st37_northcarolina).

Logical_Consistency_Report:

The ARC/INFO files have been "cleaned" and "built" to ensure complete topology.

Completeness_Report:

Linework for the 2000 Census files is based predominantly on the Census Bureau's TIGER Line files. The coverages were dissolved on the block item and selected attributes joined from the 2000 Summary File 1 by NC CGIA.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

With the exception of dissolving polygons and projecting data, no other positional changes were made by NC CGIA.

Process_Step:

Process_Description:

2000 TIGER/Line files from the Census Bureau website were converted to an ARC/INFO coverage format using TIGERTOOL. A unique id was generated for each block, block group, tract and place based on the following: Block: [State FIPS (37)] [County FIPS 1 to 199 odd, 3-digit] [Tract, 6-digit] [Block, 4-digit] Block Group: [State FIPS (37)] [County FIPS 1 to 199 odd, 3-digit] [Tract, 6-digit] [Block group, 1-digit] Tract: [State FIPS (37)] [County FIPS 1 to 199 odd, 3-digit] [Tract, 6-digit] Place [5-digit place id, unique to North Carolina] To create block coverages, the TIGER Line files were then dissolved on block, cleaned and projected from NAD27 feet to NAD83 meters projection. The individual county block coverages were then appended to create a statewide block coverage. Selected attributes were joined to the statewide coverage from Census 2000 Summary File 1.
