Abstract: This Compact Disc (CD) contains data from the 1990 Census Transportation Planning Package (CTPP). The CTPP is a set of special tabulations sponsored by the Department of Transportation in each state and designed to meet the data needs of transportation planners. The Statewide Element of the CTPP contains data for standard census geographic areas like States, counties, and places (only those with 2,500 or more persons). The Urban Element of the CTPP contains data for custom geographic areas like traffic analysis zones (TAZs), study areas, and CTPP regions. (Some areas chose census tracts or block groups (BG) instead of TAZs for their most detailed geographic level). This CD holds data from the Urban Element of the CTPP. An urban element data set has been created for each Metropolitan Planning Organization (MPO) across the country. The MPO has defined the county or counties (towns in New England) to be included in their package, and we call the resulting area a CTPP region. Each CTPP region has been assigned a unique code to identify it. Generally this is the MSA, CMSA, or PMSA code for the central area, or some variant of the metropolitan area code. Lists of the 303 CTPP urban element packages, the code assigned to each, the type of detailed geography provided (TAZ, tract, or BG), and the number of the CD on which the data are located, may be found in the \DOCS directory of this CD. The file sorted alphabetically by name is GNNAME.ASC, while the one sorted by region code is REGNCODE.ASC. The CDs in this release contain Parts 1, 2, and 3 of the Urban Element for one or more CTPP regions. Part 1 contains data for housing units, households, persons, and workers located in or living in the region, tabulated for various types of eographic units. The different types of geography are called summary levels. The counts are based on the sample or long-form data from the 1990 census, and may therefore differ from the 100 percent 1990 census counts. In Part 2 (tabulations by area of work), the CTPP provides data for workers who worked in the region. This means that residents of the region who worked outside it are excluded from Part 2. Conversely, non-region residents who worked inside the region are included in the Part 2 numbers. Since the universes for Part 1 and Part 2 are so different (residence-based versus workplace-based), the totals for any geographic unit in one part will not equal those from the other. Part 3 (tabulations of residence area by work area) includes in its universe workers who lived or worked in the CTPP region. The tables in part 3, however, are restricted to workers who did not work at home. Therefore, any at-residence or at-work summaries calculated from the commuter flow data in Part 3 will not equal the all worker counts in Part 1 (by place of residence) or Part 2 (by place of work). However, there are tables in Part 1 and Part 2 that are also restricted to workers not working at home, for example tables 1-31 and 2-8. The residence or work summaries for an area from Part 3 should equal the number of workers not working at home for that area as shown in these two tables.
