CTPP Data Products CTPP data products use data from the US Census Bureau American Community Survey (ACS) The ACS replaced the decennial census “long form” and requires accumulation of data over multiple years for small area tabulation 1 Year of data for places with 65,000+ people 3 Years of data for places with 20,000 + people 5 Years of data for smaller geographic areas, e.g. Tracts and Block Groups

5 Applications of CTPP Data Products Performance measurement Modal share analysis Environmental justice FTA New Starts/Small Starts Travel Demand Modeling Livability analysis Corridor planning Air quality modeling Trend analysis Descriptive statistics Travel forecasting

Some Key Data Items Include Data on Households –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

CTPP Data Concepts Summarized data by Place of Residence Place of Work Flows from Home to Work Custom Geography (Local TAZs) Unique Universes (e.g. workers in HHs)

CTPP Data Products CTPP Has three main data products but our focus today is only on one Data Profiles CTPP 3-year Tables CTPP 5-year Tables The CTPP 5-year Tables

5-year Geography and Flows ● Asymmetrical Flows (in red) ● Small Areas defined by MPOs in MPO areas and States Elsewhere ● Tracts are Defaults for Small Areas ● Default TADs defined by AASHTO ● UZA tables for Part 1 ONLY ● MCD Only States

2000 POW PUMAs 14 What is a POW PUMA? If the county contains two PUMAs, then those two PUMAs will be aggregated to form a POW PUMA If a county contains only a portion of a PUMA, the POW PUMA will encompass the county containing the rest of the PUMA 2000 PUMAs POW PUMAs Must comprise a whole county or multiple counties

15 PUMAs to POW PUMA Who delineated the POW PUMAs?

16 Recapping Geography ● Small Areas defined by MPOs in MPO areas and States Elsewhere ● Tracts are Defaults for Small Areas ● Default TADs defined by AASHTO ● Urbanized Area tables only available for Part 1 data ● MCD Only in 12 States
