Census Resources

Various Products and Programs from the US Census Bureau are integral in helping SRTC staff complete our duties. Some key tasks Census data is used for include inputting travel behavior data into the Travel Demand Model, monitoring and ensuring compliance with Environmental Justice and Title VI regulations, and demographic analysis.

SRTC is a designated State Data Center Affiliate. The State Data Center (SDC) program is a cooperative program between the states and the Census Bureau created to make data available locally to the public through a network of state agencies, universities, libraries, and regional and local governments.

Through SRTC’s participation in the SDC program, the agency stays abreast of Census news and releases, maintains a dialog on working with Census products, participates in peer reviews, and aids local agencies and citizens in navigating their Census data needs.
