Thanks Elaine--I hope we get to hear more about the tax records work. I am hoping it is dealing with IRS records and where we say we live and pay our taxes from. I know that LEHD uses IRS tax records for its origin (home) locations but that is something that we do not know much about. Do we live and start our journey to work at the same place we use for our tax home is one obvious question. We know a lot about QCEW and worker place data (the other half of LEHD) but we really do not know anything about the resident side. Thanks for the update and I apologize for the digression.

Hi Krishnan – Since the presentation is about Smartphones and NOT CTPP, I’ll send you a separate email and not clog up the CTPP listserv. But thanks for asking about JSM in the first place! Re: IRS. Yes, it is very difficult to get permission to use IRS records, but the Census Bureau has an agreement, which is why Amy O’Hara and Alison Fields did the presentation I mentioned. Let’s find out more about their research!

I am curious to learn about the smartphone app and data that you presented on. Is it something that you can share with us? Also, WRT tax records there was a huge study done by Harvard which uses tax records (http://www.equality-of-opportunity.org/) to look at inter-genertional mobility. So the question that naturally arises is how can Federal agencies such as FHWA get access to such data which will help explore the resident side that Ed mentioned in his email. Past experience trying to get access to such data is not very encouraging.

I had the BEST time at my one day (Aug 10) at the Joint Statistical Meetings. JSM includes many organizations including the American Statistical Association (ASA). 6000 statisticians at the Seattle Convention Center. It is like TRB for statisticians. ☺ My presentation was about using aggregate cellphone data and the test of the RMove Smartphone app in Indiana. Thank you to everyone (Sumit Bindra, Leta Huntsinger, Xian-Biao Hu, Christina Barrone and Elizabeth Greene ) whose information I used in my presentation, which was mostly drawn from the TRB Planning Applications conference and the American Planning Association conference! I had hoped to talk about the NCHRP 08-95 project on cell phone data, but that project is running 1 year behind. CB staff (Amy O’Hara and Alison Fields) did a presentation about using tax records to examine “mobility.” I missed the presentation because it was first thing on Monday morning, but Amy will send me a copy of the presentation. Their research is not yet final. The session (session 158) on interactive graphics with R was very fun but I could not stay the entire time. Here are some of the R library names: (animint) (plotly) (ggplotly) and (gridSVG). One key person with R code and involved with ASA is Carson Sievert from Iowa State. WOW! This is where I think we need to be going with big data mining and analysis. Transportation Statistics Interest Group (TSIG). (This is an equivalent of a TRB Task Force before it becomes a full committee). TSIG will continue as an interest group and may promote up to a “section” in the future. Alan Karr from RTI is the current chair. They discussed putting together 2 sessions for next year’s JSM. Feng Guo VA Tech will lead one effort, and Pat Hu will work on another (administrative records). Please contact them feng.guo@vt.edu<mailto:feng.guo@vt.edu> patricia.hu@dot.gov<mailto:patricia.hu@dot.gov> if you are interested in being a speaker. I would have liked to attend these, but since I only had one-day registration, did not. Session 516 on Wed. was “utilizing Administrative Records and Adaptive Design in the 2020 Census”. Session 541 on Wed – Cynthia Bland Augustine from RTI (member of TRB ABJ40) discussed “GeoSampling Weights and Design Effects” Session 593 on Wed – was on using the Census Bureau’s Planning Database. (see the attachment of the people who presented). I think this is a potential resource for assisting in regional and statewide surveys to better estimate low response and plan, in advance, for different recruitment or sampling design.
