  1. Transforming with the Census Ed Christopher Resource CenterPlanning Team Federal Highway Administration 4749 Lincoln Mall Dr. Rm 600 Matteson, IL 60443 708-283-3534 edc@EdtheFed.com How is the Transportation Community Transforming to meet the changes with the Census Data?

  2. Back in the Day Every 10 years the Census Bureau Counted the Population (Short Form) Sampled our Characteristics (Long Form)

  3. Short Form 100% Population count First Census 1790 Constitutionally Mandated Sets Congressional Seats Mandatory Participation $100 fine failing to respond $500 fine for lying 2010 is the 23rd Headcount In 1930 Census Day became April 1st 10 Questions Name Sex Age Relationship Hispanic Origin Race Owner/Renter Telephone Number Part Time Residency April Residents

  4. Long Form 17% Sample of Households (1 in 6) 1940 Sampling First Used All HH Occupants Constitutionally Mandated Questions Questions Change Overtime 2000 was the LAST Decennial Long Form ~ 12 pages Monthly Mortgage Real Estate TaxesIndoor Plumbing Income Occupation Educational Level Household age Number of Rooms Why is the Long Form so important to us?

  5. 1960 -- JTW Question Arrives OMB required-Metro Areas Coded to City or County No Special Tabulations

  6. 1970--First Transportation Tables Produced Urban Transportation Planning Package FHWA provided table specs First DOT funding 43 Tables, “Caveat Emptor” 112 Purchasers, Local TAZs Address coding (DIME) Block level

  7. Core Elements Summarized data by Place of Residence Place of Work Flows between Home and Work Custom Geography (Local TAZs) Unique Universes (e.g. workers in HHs) Designed and paid for by transportation planners for transportation planners

  8. 1980--UTPP Expands Census Bureau hired JTW staff -- better delivery -- geo QC Work trip imputation (allocation) 150 Buyers More detail data (more modes, vehicle occupancy, travel time)

  9. 1990--New Era Begins Census Transportation Planning Package emerges Name changed from UTPP to CTPP Wall-to-Wall Coverage (AASHTO/NARC pooled fund) First state package More data (departure time, occupancy) Extraction software BTS CD release

  10. 2000--CTPP Takes Hold CTPP Community matures TRB Subcommittee (est. 1998) ~Newsletter ~List Serve ~On Call assistance and outreach Enhanced TAZ Definition process Improved Extraction software Disclosure Rules Emerge!!!

  11. 2005--The Long Form goes away Enter the ACS era… - Continuous Survey Methodology - Conducted Monthly - About 1 in 40 Households Sampled per year - 250,000 Households Sampled per month - Same Transportation questions as 2000 Long Form - 3 basic Period Estimates Annual 65K+ 3-year > 20K 5-year, block Groups and up Smaller sample, Margins of Error (MOE)

  12. CTPP Transforms Itself Census Transportation Planning Products The CTPP embodies a collection of Census Data used for Transportation Planning. With changing data needs and the ACS, there will be a variety of different products useful for transportation planning emanating from Census Data. There will be Special Tabulations, Standard Tables and even Value Added-products. The CTPP captures all of these. Think of CTPP as a place to look for Census Data products to help with your Transportation needs
