TIGER/Line 2010 -- STATE Based Files
TIGER (Topologically Integrated Geographic Encoding and Referencing system)
This listing is for STATE based TIGER/Line 2010 data only.
To see the differences between National, State, & County based TIGER/Line data, visit this support table.
This is a US Census TIGER/Line 2010 dataset. A high level overview of the data is presented here including links to detailed technical documentation.
TIGER/Line is a format used by the United States Census Bureau to describe land attributes such as roads, buildings, rivers, and lakes, as well as areas such as census tracts. TIGER/Line was developed to support and improve the Bureau's process of taking the Decennial Census.
The TIGER files do not contain Census demographic data, but rather mapping data only. GIS can be used to merge Census demographics or other data sources with the TIGER files to create maps and conduct analysis.
Folder Structure:
TIGER/Line 2010 is delivered in folder structure by TIGER2010 > State > Files
File Naming Convention:
tl_2010_[extent]_[layer].[ext]
Where tl = TIGER/Line
Where [extent] = parent geography entity ID code
Where [layer] = layer tag (i.e. edges, faces, etc.)
Where [ext] = File extension
The entity ID code refers to a data file's geographic extent. State files have a 2 digit entity ID (ex: /41_Oregon) while county data uses a 5 digit entity ID (ex: /41051_Multnomah_County). These numbers refer to a location's FIPS code. So all data files associated with Multnomah County will have entity ID 41051 in their file name.
This TIGER/Line Listing on WeoGeo contains all the 2010 TIGER/Line Shapefiles for every county in the USA. Unlike the US Census website, county-by-county download is not required. Multiple counties or even multiple states can be ordered with a single request. This greatly simplifies the download process for Areas of Interest that cross political boundaries.
