Unfortunately, this is not as simple a proposition as with the 3 year and previous data releases (because of the total size, and because Census is not comfortable with the idea).  We are working on a solution, but our priority is to get a usable data set to the users.

Penny:

 

Will there be files for download, similar to the ACS detail tables, and will they be available sooner?

Hi All,

 

The CTPP five year data product is coming, here is some information on it.  Updates and info will be published at: http://ctpp.transportation.org/Pages/5-Year-Info.aspx

 

What:  

CTPP based on 5-year ACS – 2006 - 2010; residence based, workplace based, and flow data for geographies ranging from the Census TAZ or tract to the nation. 

Tables include means of transportation univariate and crossed with travel time, household income, vehicle availability, age, time leaving home, and (new) presence of children, minority status, number of workers in household and median household income.  A complete list of available tables can be found here: http://ctpp.transportation.org/Pages/5-Year-Info.aspx

There are plans for an API, and plans to download large files (entire states, for example) are under development.

 

How:

A new data access software is being developed for the 5-year data, it will include the 3-year data, and eventually, we hope to include both older and future data sets, so they can be found in one easy place.  The software will allow for table manipulation – so you can get a table looking the way you like before download, download formats will include tables, .shp files, .gml and .TAB files.  The software has a robust mapping component.

 

When:

A fully executed product is expected around August 2013.  As of this writing, the US Census Bureau has delivered data to the software vendor and the vendor is processing it.   Beta testing of the data and software is scheduled to begin in June with comments and modifications processed in July.

 

Please feel free to contact me on or off list with any questions.
