What is the CTPP? A set of special tabulations designed by transportation planners using large sample surveys conducted by the Census Bureau  Decennial Census Historic Urban Transportation Planning Package (UTPP): 1970 UTPP, 1980 UTPP, 1990 UTPP 2000 CTPP American Community Survey 2006-2008 CTPP, 2006-2010 CTPP (Current) Future products – 2012-2016 CTPP (late 2018) The CTPP is a set of special tabulations designed by transportation planners using large sample surveys conducted by the Census Bureau. -From 1970 to 2000, the CTPP and its predecessor, UTPP, used data from the decennial census long form. The decennial census long form has now been replaced with a continuous survey called the American Community Survey (ACS). Therefore, the current 2006-2010 CTPP uses the ACS 5-year sample for the special tabulation. --------------------------------------------------------------

American Community Survey (ACS) Background info about Decennial Census: The ACS replaced the decennial census “long form” and requires accumulation of data over multiple years for small area tabulation The Census Bureau used two different forms to collect Census 2000 data. A short form with seven basic questions went to all households and a long form with these same questions and additional questions went to a sample of households. The information that is tabulated from the questions asked of every person and housing unit is called the 100-percent or short-form data.   The long-form questionnaire included the same seven population and housing questions plus additional inquiries. This is called either the sample data, or the long-form data. DEFINITIONS: 100% Data - Population and housing information collected for all living quarters in the United States. Census - A complete enumeration (count) of a population or the business and commercial establishments, farms, or governments in an area. Long form - The decennial census questionnaire containing 100 percent and sample questions. Sample data - Detailed social, economic, and housing information collected on the long form from a selected portion of all housing units and people living in group quarters. The 1990 census sampled approximately 15 percent of the nation's population and 16 percent of its housing units. See 100 percent data. Short form - The decennial census questionnaire containing only the 100 percent questions.

What’s in CTPP? Data on Households Data on Workers Size, income, vehicles per household Data on Workers Age and gender, occupations, earnings Data on Journey to Work Usual mode to work, commuting time, work departure time Data on Workplaces Work locations, times of arrival at work

In order to balance geographic resolution, temporal frequency, statistical significance, and respondent privacy, the CTPP geography is available at TAZ level (317,526 in total). - the resolution of TAZ geography is similar to the smallest geography (block group) available in ACS, which has in total 220,334.

Analyzing Commuter Flows Santa Barbara – State of the Commute Report Summarizes commuter origin and destination Travel mode Travel time Employment by economic sector Using Residence based (part 1) Workplace based (part 2) Flow (part 3) CTPP map tools CTPP chart tools In Santa Barbara, the Santa Barbara County Association of Governments periodically produces a State of the Commute Report. The report summarizes commuter origin and destination information, and includes comparisons of travel mode, travel time, and employment by economic sector, helping transportation planners and decision makers understand trends, markets, and regional commute dynamics. The report is produced with residence based, work place based and flow data from CTPP along with a variety of other data sources, and many graphics in the current iteration are produced with CTPP mapping and chart tools. http://www.sbcag.org/uploads/2/4/5/4/24540302/state_of_the_commute_summary_full_report_final.pdf Full Report: http://www.sbcag.org/uploads/ 2/4/5/4/24540302/state_of_the_commute_ summary_full_report_final.pdf

Los Angeles – Visualizing Work Trips Helped stakeholders visual spatial interactions of small areas Increased public interest and participation The Southern California association of governments discovered that presenting the data in this visual way, along with the ability to target for specific groups of stakeholders, helped those stakeholders better understand the spatial interactions among small areas. As a result, the public took a greater interest in transportation planning and participation in the process.

Other Demographic Analysis Roadway corridor demographics Demographic Profiles CTPP data are often used to analyze race, poverty, population, and travel methods for corridor analysis, with specific attention paid to the transportation disadvantaged. The National Capital Region Transportation Planning Board and Colorado Department of Transportation both created data summaries or profiles based on CTPP data and made them available to the public.
