How time flies! Just when you thought you were getting a handle on the
journey-to-work data from the 2005 ACS, the next round of data will
released! The next set will include Place of Work tabulations. From
the CTPP world, these are like "CTPP Part 2" tables, where the
tabulation is by place-of-work, rather than place-of-residence. Since
the 2005 ACS included ALL counties in the sample, the place-of-work
tabulations should look much better than the 2004 ACS place-of-work
tabulations (about one-third of counties were included in the sample).
Don't forget:
1. 2005 ACS does not include Group Quarters population. That is, areas
with large military installations and/or college dormitories should
expect considerable differences when comparing to Census 2000 results.
2. The data are collected over all 12 months, therefore areas with
seasonal shifts are likely to see the greatest differences when
comparing to Census 2000 results.
Good luck! Nanda Srinivasan, Ed Christopher and I are trying to wrap up
our new Profile sheets using the 2005 ACS Place-of-Residence tables, but
we have had a lot of work on calculating Margins of Error and
incorporating the results into the tables.
