I had the very same problem. ESRI has a site to get that data and more. If you go to this link: http://arcdata.esri.com/data/tiger2000/tiger_download.cfm you should get the data you seek.

We have noticed that some of our TAZ boundaries look strange, as if there is a problem with collapsing polygons. Do I need to create the TAZ boundaries myself from the TIGER files? Any guidance on this would be greatly appreciated. Thanks.
