Calvin Saruwatari (thanks!) found that the link I posted no longer contains
the AFF2 Deep Linking Guide. Other links online that used to have it are
also broken. I found a copy here:

No promises it will be there in a week. :)

Happy Friday,
I promised some folks I would post this to the list. Deep linking, which has
been mentioned here a few times, is the secret ninja way to navigate around
AFF2. It's especially effective if you have set geography that you use
consistently, like all tracts in a state.
Here is a Census publication on the topic that may be more confusing than
helpful at first, but the code lists will be important if you ever get into
more advanced deep linking. The persistent URL is standardized in AFF2 and
you can basically code your way into the table and geography you want.
http://fastfacts.census.gov/home/saff/AFF_deep_linking_guide_v1.1.pdf
Here's the fast way to get started.
First, navigate AFF2 the standard way to a table of your choice. I am using
population for all tracts in Maryland, ACS 06-10, as an example. You will
need to get the persistent link for this page. That link is NOT the url in
your address bar! To get this link you must bookmark the page using the AFF2
bookmark button, not your browser's bookmark/favorite button. Bookmark the
page, go to the Bookmark/Favorite in your web browser, and look at the
properties of that bookmark. THAT is the persistent link and in the example
above it looks like this:
http://factfinder2.census.gov/bkmk/table/1.0/en/ACS/10_5YR/B01003/0400000US2
4.14000
I can use this link to get any table I want for all tracts in Maryland, ACS
06-10 by changing /B01003/ to the correct table.
/ACS/10_5YR/B01003/ is, as you might guess, your product, data set, and
table. You can change these to many different options but make sure they
agree with each other. /ACS/09_5YR/B01003/ will get me the same as above
only for the 05-09 estimates. /DEC/10_SF1/P#/ Gets you into the most recent
decennial Census data.
The end numbers control the geography. I am still working on understanding
that, as the format and length depends on exactly what geography and
combinations you are using. I am working on decoding it better and will post
a graphic or tutorial when I do.
Happy linking,
