From mkaminowitz at baltometro.org Fri Feb 3 12:57:52 2012 From: mkaminowitz at baltometro.org (mkaminowitz at baltometro.org) Date: Fri, 3 Feb 2012 13:57:52 -0500 Subject: [CTPP] Deep linking for fun and profit Message-ID: <004901cce2a5$bb8182d0$32848870$@baltometro.org> Happy Friday, I promised some folks I would post this to the list. Deep linking, which has been mentioned here a few times, is the secret ninja way to navigate around AFF2. It's especially effective if you have set geography that you use consistently, like all tracts in a state. Here is a Census publication on the topic that may be more confusing than helpful at first, but the code lists will be important if you ever get into more advanced deep linking. The persistent URL is standardized in AFF2 and you can basically code your way into the table and geography you want. http://fastfacts.census.gov/home/saff/AFF_deep_linking_guide_v1.1.pdf Here's the fast way to get started. First, navigate AFF2 the standard way to a table of your choice. I am using population for all tracts in Maryland, ACS 06-10, as an example. You will need to get the persistent link for this page. That link is NOT the url in your address bar! To get this link you must bookmark the page using the AFF2 bookmark button, not your browser's bookmark/favorite button. Bookmark the page, go to the Bookmark/Favorite in your web browser, and look at the properties of that bookmark. THAT is the persistent link and in the example above it looks like this: http://factfinder2.census.gov/bkmk/table/1.0/en/ACS/10_5YR/B01003/0400000US2 4.14000 I can use this link to get any table I want for all tracts in Maryland, ACS 06-10 by changing /B01003/ to the correct table. /ACS/10_5YR/B01003/ is, as you might guess, your product, data set, and table. You can change these to many different options but make sure they agree with each other. /ACS/09_5YR/B01003/ will get me the same as above only for the 05-09 estimates. /DEC/10_SF1/P#/ Gets you into the most recent decennial Census data. The end numbers control the geography. I am still working on understanding that, as the format and length depends on exactly what geography and combinations you are using. I am working on decoding it better and will post a graphic or tutorial when I do. Happy linking, Mara Kaminowitz GIS Analyst .........................................................................

The answer is that the smaller communities will not have any data until the the full five year file for disabilities is available. The 2000 Census overestimated disabilities and the Census Bureau has been working to improve the way that the disabilities questions are asked which has resulted in several changes in the questions/question order, which in turn, effect comparability over time. SO, the last time that the disability questions were changed occurred in the ACS 2008 questionnaire. Which means that the disability data will not be available until the 2008-2012 ACS 5 year file is available (barring any other changes in the questions). This allows for comparability over time so that 5 years of data can be combined for the smaller area estimates.

Unless you need data for special populations, STF1 and STF3 are all you need. The data are organized in large dbase files that you can import into excel . To figure out which file includes the desired table, you have to use the documentation. It is not difficult. The CDs have also extracting software that uses DOS commands and is therefore difficult to use.

Specifically FHWA's Office of Planning has updated the ?Census Issues? information on its websites to reflect Census 2010 and make it easier to find answers to common-asked questions. The websites provide information on urban/urbanized boundaries, new MPOs, designation of MPO and TMA, and the application of metropolitan planning requirements. Please visit the website(s) at: http://www.fhwa.dot.gov/planning/census_issues/urbanized_areas_and_mpo_tma In March 2012, the Census Bureau will be issuing the list of Urbanized Areas based on the 2010 Census population counts and the new criteria. The Census Bureau also plans to release TIGER/Line shape files at the same (or very close) time with these boundaries. Shortly thereafter, FHWA and FTA will prepare the Federal Register with the listing of new TMAs. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 From Stan.Williams at cityofclarksville.com Fri Feb 10 09:50:03 2012 From: Stan.Williams at cityofclarksville.com (Williams, Stan) Date: Fri, 10 Feb 2012 09:50:03 -0600 Subject: [CTPP] alternate source of disability data?

In an earlier email I said that the Census Bureau was researching how they might be able to issue disability data from ACS prior to 2008-2012 5-year summary. Yesterday, Alison Fields told the CTPP Technical Group that although the concept of building a bridge between the 2 different question wording had been discussed, under further investigation, they (CB) determined it was not feasible. Bottom line: have to wait for 2008-2012 ACS for small geography disability data (from ACS).

There are many types of disability which do not qualify for OASDI; hearing problems come to mind immediately. Overall, people who are able to work generally do not get help from the SS disability insurance program. Further, iI don't think it provides no count of disabled people who are eligible for and collecting regular "old age" social security, since when they become age eligible they would transition. We'd have to confirm that situation, statistically, with SSA. Many people under 65 collect "old-age" social security, since it's available on an "early" basis at age 62. Currently, you have to be 66 to get full benefits, but you can defer beyond that and get larger benefits later on. It might be a reasonable count of the population 65 and older by zip code, but census data would be better. It's really, really hard to use administrative data of this type for statistical purposes. I'm sympathetic to the transportation community's need for disability data and understand the frustration over its not being available right now from ACS, but I don't think this is the solution.

Also, I just had the FHWA webpage on ACS updated to include the information below: Census Bureau hotlines: AFF: 1-800-923-8282 Data Ferrett: 1-866 -437-0171 Census Bureau Regional Offices: http://www.census.gov/regions/ I have found that the Census Bureau Regional Offices have Information Specialists who do training on AFF2, which is why the first "cheatsheet" we did on AFF2 was taken from materials provided by Linda Clark in the Seattle regional office. I didn't look up on the map which region covers you, but I am going to guess Atlanta. And certainly, we can arrange another webinar on using Data Ferrett for very large downloads, but I think the answer to that one is that it is probably better to do multiple downloads and then join them outside of Data Ferrett.

These data were provided in addition to a much smaller set of "profile" data that we felt was very useful for transportation planning. Lately, we have been thinking about whether or not to take the Table chooser approach with the new ACS data. We would be interested in feedback about your potential interest in this and whether it would address the problems that folks are having with Census downloads.

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/PCT035/0400000US05.05000|0400000US05 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/PCT079/0400000US05.05000|0400000US05/popgroup~400 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.

One question - How did the Stats Netherlands people get access to the data from the cellphone providers? Maybe there are some lessons there about structuring the request and alleviating public fears that can be useful to data collection efforts here. Or did they select their sample and then approached the providers with explicit permission from this sample of the cellphone customers. In general, my impression is that overseas it is a bit easier for agencies to obtain data than here.

I tried, but failed. I'll share this with the list serve because it may be instructive to others. I'm probably missing something simple, but this may help reveal the (multiple) fallacies of AFF2. After selecting the county geography, I did as you said in the message below: I typed in "labor force age sex." This was great. I got a long list of 2010 ACS tables, but at least they resembled what I'm looking for. Then I typed in "2000 SF3" and got: "No tables, files or documents were found that match . blah blah." What am I doing wrong here? When I try scrolling through the multiple pages of results, I go through two pages of 2010 ACS. Then I run into 2009 ACS. How many dozens of pages must I scroll through to get Census 2000? I also can't help but use this as commentary on AFF2. I'm a data user with years of experience and training. If I can't easily find what I need, what hope does the general public have? Very little of Census 2000 is available in printed form. Will it become the "dark age" Census, that nobody can get to? Again, thanks for taking the time. I would like nothing more than to be able to make full use of AFF2.

Then all the tables you bring up are restricted to those in that one dataset. The ACS labor force/age/sex table is B23001. After selecting the dataset, you can type the table number into the selection box and click go, and then it will bring up the one table and you can click the box and "view." It's still way too many clicks If you want 2000 data, select 2000 SF3 as a dataset and then just type "labor force" in the box. You'll get an assortment of tables and you can choose the one you want. We all hate AFF2, although our lists of pet peeves may vary in content. Mine are (1) you can only retrieve one table at a time, and (2) the download options are horrible. The simple csv option to be opened in Excel does not exist. When you select the xls option, you get a table which has left-justified numbers and weird columns. You can fix this, but it's a burden. If instead you choose to get a csv table for use as a database, the rows and columns transpose. This is fine if you have a lot of geographic areas and a table with few cells, but lousy otherwise. If you try to transpose it back the "estimate" and "margin of error" rows are interleaved. There simply are no good download options.

One question - How did the Stats Netherlands people get access to the data from the cellphone providers? Maybe there are some lessons there about structuring the request and alleviating public fears that can be useful to data collection efforts here. Or did they select their sample and then approached the providers with explicit permission from this sample of the cellphone customers. In general, my impression is that overseas it is a bit easier for agencies to obtain data than here.

My attached notes do not cover my (and Evan Burton's) presentation. It is always interesting to see what people are trying, given that we have so many of the same problems: cell-phone only households, incentives, non-response, quality of response, disclosure avoidance, etc. So, even if this post is not specifically about CTPP, there are some tidbits related to ACS and census research at new university centers.

A tip that has helped me is to drill down as far as I can using those boxes on the left (geography, dataset, variable... I usually do it in this order and have had good luck) and what I am looking for generally arrives on the first page. Another tip, be sure to clear your basket between searches. If you have elements of a previous search it can get confusing and will lead to frustrating messages about variables or geographies not being available.

Many thanks to Nancy Gemignani - you got me on the right track. I had to scroll through seven screens of ACS 2010, 2009, 2008, etc. to finally retrieve Census 2000 SF-3. Does anyone know if there's a shortcut without all this scrolling? I remember asking about this at the AFF2 training webinar in October, and I don't think there was a good answer. Once ACS 2011, 2012, 2013, etc are up there it may take 27 screens to get back to Census 2000. Patty, I agree that the AFF2 downloads are also sometimes a mess. I have designed a macro that takes out the MOE columns, which are reliably every other column. It's scary to run, because it feels like taking a meat cleaver to your data, but actually works well. You can save your data first just to be safe. I remain astonished that they took something that worked pretty well ("Legacy" FactFinder) and, rather than building on what was good, they junked it, put on dunce caps, and came up with the resulting mess. I think it's an "emperor with no clothes" situation, the typical product of top-down hierarchical bureaucracy in which underlings know there's a problem, but the information isn't allowed to climb the command chain. But I digress. Deep linking looks promising, but working for an MPO I'm wearing a lot of hats, and haven't found time to go there yet. Thanks everybody for the helpful tips. I'd still like another webinar on advanced use of Data Ferret.

Then all the tables you bring up are restricted to those in that one dataset. The ACS labor force/age/sex table is B23001. After selecting the dataset, you can type the table number into the selection box and click go, and then it will bring up the one table and you can click the box and "view." It's still way too many clicks If you want 2000 data, select 2000 SF3 as a dataset and then just type "labor force" in the box. You'll get an assortment of tables and you can choose the one you want. We all hate AFF2, although our lists of pet peeves may vary in content. Mine are (1) you can only retrieve one table at a time, and (2) the download options are horrible. The simple csv option to be opened in Excel does not exist. When you select the xls option, you get a table which has left-justified numbers and weird columns. You can fix this, but it's a burden. If instead you choose to get a csv table for use as a database, the rows and columns transpose. This is fine if you have a lot of geographic areas and a table with few cells, but lousy otherwise. If you try to transpose it back the "estimate" and "margin of error" rows are interleaved. There simply are no good download options.

I tried, but failed. I'll share this with the list serve because it may be instructive to others. I'm probably missing something simple, but this may help reveal the (multiple) fallacies of AFF2. After selecting the county geography, I did as you said in the message below: I typed in "labor force age sex." This was great. I got a long list of 2010 ACS tables, but at least they resembled what I'm looking for. Then I typed in "2000 SF3" and got: "No tables, files or documents were found that match ... blah blah..." What am I doing wrong here? When I try scrolling through the multiple pages of results, I go through two pages of 2010 ACS. Then I run into 2009 ACS. How many dozens of pages must I scroll through to get Census 2000? I also can't help but use this as commentary on AFF2. I'm a data user with years of experience and training. If I can't easily find what I need, what hope does the general public have? Very little of Census 2000 is available in printed form. Will it become the "dark age" Census, that nobody can get to?

They have supplied this cellphone data to several transportation companies for further use and analysis as well as supplying products themselves. This is described on their website. I know researchers in Europe who have gotten very rich data allowing tracking of individual cellphones throughout the day without any disclosure of the actual owner. Each time the cellphone is turned on it is assigned an ID number which is not the cellphone number. This location can be tracked because they must know which cell tower it is connected with at all times. The location is reported back to the company whenever a call is made or received or a text message is sent or received. If it is on, but not being used, it reports every two hours to keep the cell tower location active. By seeing where the phone is for many hours overnight the home location can be assumed. Then, when it moves in the morning and then is steady at one location, that is assumed to be the work location. However, there is no guarantee this is work, it may be shopping, school, or other. Of course, when using a "smartphone" many of the apps report back using the GPS (or the cell tower location if the GPS is turned off) to supply the location aware information. For example, when you use the map application, this reports your location and speed back to report traffic conditions. This data can be further mined to provide OD data. INRIX, TomTom, and others use this GPS data for traffic data analysis and routing recommendations, but it can also be used for OD. WSDOT and UW researchers have used truck GPS data sources to determine freight bottlenecks and truck OD and there are reports available for download. Because these are all samples, and the purpose of the trip needs to be assumed, there are still some further data needs, but this helps fill more pieces of the puzzle. My experience is the cellphone data, while usually good enough for most TAZ to TAZ movements, is not location specific enough for a detailed TAZ system. We still don't know the actual origin and destination due to the resolution of the cellphone data (based upon triangulation with the towers) or we could tie that in with GIS data and perform some very detailed analysis. For an example of the spatial resolution, when looking at using this data for a detailed study, we "watched" some historical data from one cellphone that was probably being used for calls from an office that moved randomly (and sometimes what appeared to be very quickly) over a 4 block area. This location data may have better resolution in Europe as they use only GSM cellphones whereas in North America we have both CDMA and GSM. I hear the location issues for those are somewhat different but I don't know more than that. I recommend if you want more information on cellphone data to contact Airsage or for GPS data contact INRIX or TomTom or others. I hope this is helpful.

Groves, Director, U.S. Census Bureau I would like to invite you to provide your insight and advice on the methodologies employed and products developed by the American Community Survey (ACS) Program. In December of 2010, the ACS program released its first five-year data products. With this important milestone achieved, we decided that a comprehensive assessment of the ACS program was prudent to ensure its continued effectiveness. I commissioned the ACS Program Review Team to plan and implement this assessment. As a key stakeholder and advocate of the ACS program, your assistance will help us obtain a broad and more robust perspective, as we continue to shape our program in the coming years. We are offering the following information sharing and engagement options: * Provide recommendations and comments by completing an online feedback form (http://www.census.gov/acs/www/about_the_survey/program_review_feedback/ ) or filling in a Word Document and sending it to ACS.Program.Review at census.gov; * Learn more by visiting our website (http://www.census.gov/acs/www/about_the_survey/acs_program_review/ ); or * Ask questions by attending an interactive webinar where we will provide details about the program review. To this email, I have attached the feedback template and the PowerPoint presentation that we will use to facilitate the webinar. Any feedback collected from you by the ACS Program Review Team will be shared with a National Research Council panel, which is conducting an independent review of the ACS program. A member of the ACS Program Review Team will follow up with you shortly to provide logistics on the program review webinar. Thank you in advance for any feedback you wish to provide. * ACS Program Review Briefing Slides 2-21-12.pdf * ACS Program Review Feedback Form - Word pre-2007.doc * ACS Program Review Feedback Form - Word 2007 .docx ________________________________ US Census Bureau Questions?

The limitations of these files are listed on the CB website as follows: "The generalized files have a much smaller file size than the original file extraction from the Census Bureau's TIGER database, resulting in faster download and processing times. Limitations Because of coordinate thinning: 1. Cartographic boundary files should not be used for geocoding; 2. Some offshore, redundant, zero population and housing land areas may be absent from the files; 3. Cartographic Boundary files are not necessarily vertically integrated with previous boundary file sets." For smaller geographies such as TAZs, you are better off using a detailed shape file/Any other GIS file derived from TIGER directly.

Was this delineation done purposefully or perhaps these are simply errors stemming from TIGERLine 2000? Any input will be much appreciated. Thank you.

The limitations of these files are listed on the CB website as follows: "The generalized files have a much smaller file size than the original file extraction from the Census Bureau's TIGER database, resulting in faster download and processing times.

For smaller geographies such as TAZs, you are better off using a detailed shape file/Any other GIS file derived from TIGER directly.

The software used in 'TAZUP' at the time was not as thorough, so to speak, as that used this time around. Visually scanning the map that was on the computer screen before you often required 'zooming in' to locate missing polygons; they were often rather difficult to spot. I do not recall that the software had any 'checks and balances' like it did for the 2010 work effort. Consequently, the situation you indicated could quite possibly have taken place. I believe that I had a few instances like you described. Fortunately, they were tiny slivers. Good luck with the work!
