[CTPP] Question about PUMS data and Geography

[Catala, Martin]

Hello, 

I am looking to create some commute flow maps and I think I remember
someone mentioning (between all the please remove me from this list
e-mails) that flow maps can be created by using ACS data and the PUMS
geography.  I was at the Census site trying to download the PUMS
geography files and found that there were two types 1% and 5%.  Does
anyone know which geography file I should use?  The 1% or the 5%?
Thanks in advance,
