Boundary and Annexation Survey (BAS) MAF/TIGER Partnership Software (MTPS) FAQs and Tips

What is the username and password for downloading the MAF/TIGER Partnership Software (MTPS)?

The Census Bureau will email the setup file, username and password to the BAS contact five days after you fill out the Annual Response Form.

The five day waiting period will give the Census Bureau staff time to update the BAS contact record if necessary so that the email reaches the right person. The subject line of the email contains the text: ‘Digital Submission Information’. Email if you do not receive this email with the username and password after the five days.

How can I determine the fringe counties that are needed by MTPS?

To determine which counties you will need to download shapefiles for, right click on the SetupFile_BAS15_<id#>.xml (that was emailed to the BAS contact) and open with WordPad. When the file opens, go to the “<CoreCountyCoverage>” for the core county and “<FringeCountyCoverage>” for all the fringe counties. You will need to download all the counties listed in those two lines.


For the above example you would need to download shapefiles for 04021, 04007, 04009, 04013, and 04019.

Is there MTPS training available for new users?

MTPS comes with built-in Computer Based Training Tutorials to assist new users in learning how to use the basic functions of MTPS in addition to more detailed instructions relevant to BAS. When opening MTPS, choose 'Run the MAF/TIGER Partnership Software Computer Based Training' as your startup choice. We recommend that you go through the tutorials under Basic Skills and BAS.

Informational and tutorial videos on a variety of BAS related topics are now available on our BAS Videos and Webinar page.

When will my changes be reflected?

This depends on the type of changes you submit, when you submit them, and (for boundary corrections) the number of changes in your submission. Any legal boundary changes which are received by the deadline of March 1st and were effective by January 1st of the same year will be reflected in the products from the same year's American Community Survey (generally this data is available in July of the same year). All legal boundary changes received after March 1st but before May 31st will be reflected in the next year's BAS products. Boundary corrections and feature changes will generally all be reflected in the next year's BAS products, but if you submit a very large file with many boundary corrections or features changes, we cannot guarantee that all of them will be reflected. In that case, any remaining boundary corrections and feature changes will be processed as time and resources permit. The Census Bureau appreciates your understanding and support in this matter.
