Here is some Perl code which you might find useful to extract the data you
want. This code is written to obtain specific ACS data tables from tracts
in multiple counties and put it all in a single file. The README tab
describes the process in detail. You can modify it to fit your needs.
Hope it helps.

Jonathan, Sounds like you have found the table and
have a simple
geography (counties). I would have downloaded the table as a csv file and
open it in excel. Manipulate it there to remove the variables you don’t
want and calc the LFPR. ****

Are you looking for something that will extract the exact cells (total pop
and in LF) you need? You could use the “modify table” function in AFF but
I agree – at this time that is kinda clunky and slow - because you can only
make one change at a time. But to me AFF to Excel is much faster than
DataFerrett for pulling a table for multiple geographies. I guess it is
just what you are comfortable with. ****

Using the info, Mara Kaminowitz from Baltimore sent out earlier this
month, once you know the specific table you want, you can construct a
direct link like this one which will pull table PCT 35 from 2000 SF3 for
Arkansas statewide and all its counties:****
http://factfinder2.census.gov/bkmk/table/1.0/en/DEC/00_SF3/PCT035/0400000US…
****

BTW – this table is also available by race as table PCT079 in SF4. Its
link to the data for Hispanics would look like this:****
http://factfinder2.census.gov/bkmk/table/1.0/en/DEC/00_SF4/PCT079/0400000US…
****

I have found that that the text search feature has greatly improved in
AFF2. I typed “labor force age sex” (219 results) then selected 2000 SF3 (
*1 result*). Now pick your geography. A handful of clicks got me to the
data. If you are not familiar with the tables in the census data files,
the search is actually improving into a useful tool. ****

I much appreciate the efforts by Elaine Murakami and others to help with
the AFF2 problem by providing the recent webinars in AFF2 and Data Ferret.
I must reluctantly confess that I am still struggling, and would like to
know how other members on the CTPP list serve are faring. Here are my
conclusions at the moment:****
** **
**1. **AFF2 is useful for obtaining pre-organized data profiles
(despite its clunky and counter-intuitive interface), but in my experience
it’s still hard – even with the benefit of some training – to really drill
down into the kind of esoteric data I sometimes need.****
**2. **Data Ferret is great for batches, like downloading a fair
amount of data for multiple geographies (like all BGs in a county, etc.)
but I’m having a hard time drilling down to the highly specific items I
need.****
** **
My latest troubles involve trying to get employment/labor force
participation by age and sex for counties and/or my metro area from SF-3 in
Census 2000. I have been able, with the help of Data Ferret, to obtain the
table numbers (PCT 3500-PCT 3518), but Data Ferret can’t seem to give me
the figures I need in a single download, and multiple downloads are proving
error-prone and troublesome. Searching the table numbers in AFF2 yields the
typically useless results. My search of the Missouri State Data Center
site, while much appreciated, hasn’t yielded the results I need. My own
State Data Center (Arkansas) has some useful profiles, but again not as
specific as I need.****
** **
Does anyone else have tips? ****
** **
I feel like I could use further webinars on Data Ferret or – just possibly
- AFF2, although I’m deeply suspicious of trying to make anything useful
out of AFF2, since results so far have been disappointing. The seminar on
Data Ferret back in December was helpful, but didn’t have a lot of in-depth
training on large downloads, highly specific data needs, etc.****
** **
I’m deep in ‘flyover country,’ and hence there’s a lack of training and
information exchange available. Surely others face the same issues. Does
anyone else want more web-based training, too?****
