   Overview
The Census Transportation Planning Package (CTPP) is a cooperative effort sponsored by the State Departments of Transportation and the Federal Highway Administration under a pooled funding arrangement with the American Association of State Highway and Transportation Officials (AASHTO). It provides a wide variety of transportation data for state and local areas.The CTPP 1990 is a collection of summary tables generated from the 1990 census short- and long-form, that contain information about population, household characteristics, worker characteristics, and characteristics of the Journey-to-Work (JTW). The CTPP is organized into the following two elements: State and Urban. The State Element of the CTPP consists of data summaries for all places of 2,500 or more population, the balance of the county, the county as a whole, and the entire state. The Urban Element of CTPP consists of data summaries for urbanized areas with a population of 50,000 or more. It should be noted that the CTPP does not contain raw census information, rather the information provided, as with all other census products, has been organized into a series of tables. The CTPP 2000 data will be released in 2003.
   Coverage
CTPP provides state and local data for the 50 States and the District of Columbia.
