Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attributes for the 112th Congressional District data set were created in a consistent manner using similar tolerances.

Quantitative_Attribute_Accuracy_Assessment:

Attribute_Accuracy_Value: unknown

Logical_Consistency_Report:

All node-link and polygon topological relationships were created and verified using ARC/INFO, a Geographic Information System. The unique identifiers were verified using ARC/INFO. The data was then converted to a shapefile format.

Completeness_Report:

This data set is composed of the 437 Districts having voting representation plus two districts without voting rights the District of Columbia and Puerto Rico.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The Congressional District data set was created from TIGER/Line data having a nominal scale of 1:100,000.
