The Census Bureau, Geography division has noticed that a few participants have submitted new equivalency files, even though they had no/very few changes to the TAZ layer in TIGER. Please note that: 1. If you have no changes to the TAZ layer, you only need to e-mail Valerie Murdock (vmurdock(a)geo.census.gov) and Carrie Saunders (csaunders(a)geo.census.gov) at the Census Bureau informing them that you have no changes. 2. If only a few TAZs (eg: fewer than 20 TAZs) need changes, you can submit sketch maps with supporting documentation to your regional Census Bureau liason. For a list of Census Bureau regional office contacts, please see the attached pdf file. 3. If a substantial number (eg: more than 20 TAZs) need changes, you will need to upload the new equivalency file through the Census Bureau website at: http://www.census.gov/cgi-bin/taz/sendfile If you submitted an equivalency file, but have fewer than 20 TAZs than need changes, please call Carrie Saunders at 301-457-1099 (e:mail csaunders(a)geo.census.gov") If you have any questions, please call me at (202) 366-5021 (e:mail ctpp(a)fhwa.dot.gov) Thank You Nanda Srinivasan
