Back in the Day

Every 10 years the Census Bureau

Counted the Population (Short Form)

Sampled our Characteristics (Long Form)

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
