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
10 Questions Name Sex Age
Relationship Hispanic Origin
Race Owner/RenterTelephone Number
Part Time ResidencyApril Residents
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
4
Long Form
1940 Sampling First Used
All HH Occupants
Constitutionally Mandated Questions
Questions Change Overtime
2000 was the LAST Decennial Long Form
17% Sample of Households (1 in 6)
~ 12 pages Monthly Mortgage
Real Estate TaxesIndoor Plumbing
IncomeOccupation
Educational LevelHousehold age
Number of Rooms
Why is the Long Form so important to us?
5
OMB required-Metro Areas
Coded to City or County
No Special Tabulations
1960 -- JTW Question Arrives
6
FHWA provided table specs
First DOT funding
43 Tables, “Caveat Emptor”
112 Purchasers, Local TAZs
Address coding (DIME) Block level
Urban Transportation Planning Package
1970--First Transportation Tables Produced
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
Census Bureau hired JTW staff
-- better delivery-- geo QC
Work trip imputation (allocation)
150 Buyers
More detail data (more modes, vehicle occupancy, travel time)
1980--UTPP Expands
9
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
1990--New Era Begins
Census Transportation Planning Package emerges
10
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!!!
2000--CTPP Takes Hold
11
Enter the ACS era…
2005--The Long Form goes away
- 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)

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
CTPP Transforms Itself
