This came across the census news today. This could be the start of something big. Web Transformation Census Application Programming Interface (API) — The Census Bureau is releasing its first ever API. This online service provides the building blocks for developers to design online and mobile apps, such as interactive maps, charts and databases, using a variety of Census Bureau statistics. The API provides statistics down to the neighborhood level (tracts and block groups) from the 2010 Census Summary File 1 and the 2006-2010 American Community Survey. With these two datasets available in the form of an API, database editors and other developers have easier access to a wide variety of timely, localized information, including population totals, age, sex, race, Hispanic origin, home ownership, education, income, employment, commuting and occupation. The API is currently undergoing beta testing and is scheduled for public release in July. More information about the API can be found at <http://www.census.gov/developers/>. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

[CTPP] Sharing prototype of travel survey data visualization tools developed by ORNL

by Elaine.Murakami＠dot.gov

http://nhts.ornl.gov/det/ Data Visualization Prototypes from Oak Ridge National Labs, for Federal Highway Administration I don't know how long these tools have been available on the NHTS website, but I found them a couple of weeks ago. I thought I would share the link because these ideas might be useful for : 1. People who are working on the Commuting in America project 2. People who have their own regional or statewide household survey and plan for interactive web-based data access tools If you have questions about NHTS: a contact list is available here: http://nhts.ornl.gov/contactUs.shtml If you have questions about the data visualization prototype, please contact Dr. Ho-Ling Hwang at hwanghl(a)ornl.gov<mailto:hwanghl(a)ornl.gov> Elaine Murakami FHWA Office of Planning 206-220-4460 (in Seattle)

[CTPP] NTD Urbanized Area

by John Voges

NTD recently released their guidelines, their Allocation of NTD Data/2010 Census form letter, and 2 spreadsheets showing the urbanized areas in the US and their corresponding populations. These are the UZAs and population that must be used. If your transit coverage also includes areas outside of these UZAs, then there's accommodation for that as well. -----Original Message----- From: ctpp-news-request(a)chrispy.net [mailto:ctpp-news-request(a)chrispy.net] Sent: Tuesday, June 26, 2012 12:24 To: ctpp-news(a)ryoko.chrispy.net Subject: ctpp-news Digest, Vol 100, Issue 13 Send ctpp-news mailing list submissions to ctpp-news(a)ryoko.chrispy.net To subscribe or unsubscribe via the World Wide Web, visit http://ryoko.chrispy.net/mailman/listinfo/ctpp-news or, via email, send a message with subject or body 'help' to ctpp-news-request(a)ryoko.chrispy.net You can reach the person managing the list at ctpp-news-owner(a)ryoko.chrispy.net When replying, please edit your Subject line so it is more specific than "Re: Contents of ctpp-news digest..."

Additionally, FTA is required by law to use these new Urbanized Areas for the Fiscal Year 2013 Apportionment, which will be based on NTD Report Year 2011 Data. We are expecting that the Census Bureau will very soon be releasing the final Urbanized Area Boundary maps from the 2010 Census. This e-mail is to provide you with additional information on how that process will work. Upon release the Census Boundary maps for the 2010 Census, each of you must identify which Urbanized Area (UZA) or Areas are served by your transit system. In addition, you will need to identify whether your transit systems services any rural or non-urbanized areas. An area is served by your transit system if you pick up passengers in that area. (Note: Some demand response systems allow passengers to travel to a particular location, but do not allow trip originations in that area. In this case, do not list these destinations as ?served? by your transit system.) Please note that you must identify all areas served by your system, regardless of whether or not you plan to allocate service data to those areas. Is this the same as the already released Census urbanized areas (what is new from what has already been released?) Can we submit our Federal Aid Adjusted Urban Area instead? Or just stick to a Census define boundary of urbanized. Thanks Earl T.

[CTPP] Urban Area Webinar

by Ed Christopher

On March 27, 2012 the Census Bureau released the list of new Urbanized Areas and Urban Clusters. For transportation related activities these boundaries have broad and far reaching affects.

Federal Transit Administration, Census Bureau and others will conduct a 2-hour webinar on Boundary Issues and Transportation. Participants in the webinar can expect to learn about the various Transportation related boundaries, where and how they interact with the federal programs and the steps that state and local agencies need to take to address the boundary related requirements. Time will be allowed for questions and discussion, and additional resources will also be made available for downloading. If you are interested in boundaries from a transportation perspective, have a particular question or need to learn about them, this webinar is for you. To make sure your questions get addressed you can send it send them to ed.christopher(a)dot.gov up to the close of business the day before the before the webinar, otherwise they will be handled on a first come basis during the webinar.

[CTPP] ACS Hearing Tuesday

by Ed Christopher

Here's the latest update on the Congressional ACS hearing... If any of our CTPP friends attend or sent in testimony and want to report back I am sure those on this listserve would be interested in hearing from you. -----Original Message----- From: Terri Lowenthal [mailto:terriann2k(a)aol.com] Good afternoon, Census Project stakeholders. Just a reminder that the congressional Joint Economic Committee will hold a hearing tomorrow (June 19) at 2:30PM to review the economic consequences of eliminating the Census Bureau's American Community Survey and other federal surveys (such as the quinquennial Economic Census). The Census Project encourages stakeholders in the Washington, DC area to attend this hearing in person, to demonstrate strong interest in and support for the ACS and other core Census Bureau programs. See the link on my Facebook page for more details about the hearing. However, if you are unable to attend, the committee will web case the hearing. Here's the link (to the best of our knowledge ... if it doesn't work, please go to the Joint Economic Committee home page!): http://www.jec.senate.gov/public/index.cfm?p=Hearings&ContentRecord_id=831b… Also, FYI, Rep. Carolyn Maloney (D-NY), who is presiding over the JEC hearing, will hold a short press conference at noon tomorrow at the House press "Triangle," to call more attention to the serious consequences of the House vote to eliminate the ACS and to encourage cooler heads to prevail. In addition to Rep. Maloney and a few other members of Congress, Wade Henderson (President/CEO of the Leadership Conference on Civil and Human Rights) and senior representatives from the National Association of Realtors and National Electrical Manufacturers Association will speak. For those of you who don't follow the legislative agenda closely, there is still no word on when the U.S. Senate will consider the FY13 Commerce, Justice, and Science Appropriations bill. Due to a whole range of election year politics, it might not before the election. However, at some point before this Congress adjourns, lawmakers must agree on a funding bill for the Census Bureau for fiscal year 2013, and they must resolve the issues of ACS funding, voluntary versus mandatory ACS response, and adequate funding for 2020 Census planning and the 2012 Economic Census. So we must use the time now to continue educating all lawmakers (both chambers, both parties!) about the importance of the ACS and the serious policy implications of eliminating the survey or making response voluntary. Thanks for your continued support and efforts. We will keep you posted!

[CTPP] Congressional hearing on consequences of eliminating the ACS & Economic Census

by Ed Christopher

I got this email from friend Terri Ann at the The Census Project ------------- Good evening, Census Project colleagues. A brief follow-up to Phil Sparks' earlier memo regarding the Joint Economic Committee hearing scheduled for June 19, to review the consequences of eliminating the Census Bureau's American Community Survey and Economic Census. 1. Below is a hearing notice from congressional staff. As Phil mentioned, the hearing is open to the public, and we urge census/ACS stakeholders in the Washington, DC area to attend, to demonstrate interest in and concern about this issue. 2. Rep. Carolyn Maloney (D-NY), House Democrat on this bipartisan (evenly divided), bicameral committee, will preside over the hearing. Rep. Maloney has invited stakeholder organizations to submit testimony "for the hearing record." For those unfamiliar with this procedure, a committee may include, in the official hearing record, statements from interested parties who did not testify at the hearing. The statement should be directly relevant to the topic of the hearing. While it usually can be of any length, I suggest statements between one and five pages only (single or double spaced), concise and to the point, demonstrating concrete consequences to your organization, members, or constituency of eliminating these vital, core Census Bureau programs. Statements should bear the title, committee name, and date of the hearing at the top. The first sentence or two should indicate in some fashion that you are submitting the statement for the hearing record (and appreciate the opportunity to do so!). Here's an example: Written Statement of Americans for Census Data, Inc. Submitted for the Hearing Record "The Economic Impact of Ending or Reducing Funding for the American Community Survey and Other Government Statistics" Joint Economic Committee Congress of the United States June 19, 2012 It is appropriate to begin your statement by addressing the senior committee members from both parties (whether or not they are in attendance): "Congresswoman Maloney (presiding), Chairman Casey, Vice Chairman Brady, Senator DeMint, and Rep. Hinchey: Thank you for the opportunity to submit a statement for the official hearing record, expressing [name of organization]'s deep concern about the proposed elimination of the Census Bureau's American Community Survey and the possible cancellation of the 2012 Economic Census due to insufficient funding in fiscal year 2013." (Of course, feel free to address one or the other or both of those specific Census Bureau programs, based on the focus and work of your organization or institution.) You may submit all statements electronically to the Office of Rep. Carolyn Maloney, attn: Elizabeth Darnall, at <Elizabeth.Darnall(a)mail.house.gov>. Be sure to include a clear subject matter line for Elizabeth: "Statement for the Hearing Record in Support of the ACS/Economic Census" (or something similar). You should send statements to Elizabeth no later than close of business on Monday, June 18. (Sorry for the short notice, but that's how things work on the Hill!) Those of you with state and local organizations/institutions should consider sending a copy of your statement, with a brief cover note/email of explanation, to your own representatives and senators, to let them know of your continued concern about and interest in this issue.

[CTPP] Friday July 13 at 1:00 -2:30 p.m. Eastern " Deep Linking with Census AFF"

by Elaine.Murakami＠dot.gov

Deep Linking is a way to access material by using pointers (or bookmarks). As an example, some tutorials on deep linking explain how to link to a specific time within a YouTube video, but in our case, we are going to learn how to build URLs that you can use in a website, or for doing quick queries to ACS tabulations without using the AFF interface. If you understand the text below, you do not need this webinar. If it looks like gobbledygook, you might consider attending! factfinder2.census.gov/bkmk/table/version/lang/program/dataset/product [/geo_id[|geo_id]*][/codetype~code[|code]*]* We will have 2 presentations: Mara Kaminowitz, Baltimore Metropolitan Council: Introduction to Deep Links Eric Kramer, Pima Association of Governments: Overview of the AFF2 Deep Linking Database Tool We will have plenty of time for questions and answers. We will use my regular CTPP room, without requiring reservations. https://connectdot.connectsolutions.com/ctpp1 This room hold 100 people. Please enter as a "guest" and type in your name. 1-888-675-2535 pc = 5860415# Let's have a good learning experience on Friday the 13th of July.

Re: [CTPP] ACS/CTPP vs LEHD

by Graham

Reading the documentation of the two data resources: always a good place to start. At regional or state level of summary, totally different data frames is your main issue: a. Census ACS counts workers through a household survey, relying on individually-provided info on work. Many kinds of work are counted, including self-employment and occasional casual work. b. Meanwhile, the LED uses the data frame of BLS QCEW, counting wage & salary jobs that are "covered" by the Unemployment Insurance system. In Minnesota, over 20% of BEA-counted jobs (a broader employment concept) are outside of this frame, are *not* covered, and thus not counted in LED. At local level, there are still other issues: a. How well can Census ACS represent job locations? b. And does the LED program move its workplace locations around on the map, in order to obscure exact location? Hope that helps. Good luck.

I was hoping someone on the mailing list might be able to provide assistance. I've been working with Longitudinal Employer-Household Dynamics (LEHD)in On the Map. Specifically worker inflow/outflow analysis at the county level. I've discovered that there is a significant difference between the LEHD data and ACS Place of Work data from the 2008-10 3-Year ACS product. I've found that for the Middle Tennessee (Nashville) region the % of workers residing outside their home county is nearly 17 percentage points higher in the LEHD data than in the ACS data. Please see the attached table. I've been tasked with determining the reason(s) for this difference.
