Hello Penelope:
I hope you had a great summer and now enjoying this cooler weather. I don’t know if you remember me but I formerly worked for NJ Transit with Tom Marchwinski and we met at a few conferences, workshops and training sessions.
I am working on a project to analyze how journey-to-work flows have changed for Counties in the New York/New Jersey Region. [Next I’ll be doing the same for combinations of Census Tracts]. I am using the ASCII files from the 2000 Census CTPP Part III and the 2006-2010 ACS CTPP Part III and writing scripts in IBM Statistics (formerly SPSS) to do this.
Based on the documentation I read for these two datasets, the 2000 dataset for NY contains data for workers travelling from NJ to NY while the 2006-2010 data does not. To get these flows from the latter dataset I need to add the NJ and NJ datasets. True? Also, could you advise whether there is a difference in the definitions for the two datasets: the Universe for 2000 is ALL WORKERS while that for 2006-2010 says WORKERS 16 Years and Over. What’s the difference?
Thanks.
Terrence.

Thanks Brian, this is awesome!
A great interim product between two full blown CTPP tabulations. The current data, based on the 2006 – 2010 ACS is out now, and the next non-overlapping full tab be based on the 2012 – 2016 ACS (we skipped a year, to take full advantage of the increase in sample size) is expected in late 2018.
So all you data-philes can use this county level data until the next thing rolls our way…

Good morning,
Just wanted to give a heads up that the new county commuting flows, based on the 5-year 2009-2013 ACS were released today. The tables include the typical worker flow counts as well as a means of transportation component (4 categories: drove alone, carpool, transit, other). The tables also include a metropolitan area indicator, so it is possible to sort and organize by metro area.
Enjoy,
Brian
