[CTPP] Interim 2010 product between PL 941171 and SF1

by Charles Purvis

Hello: Question and a comment. Question: Will the Census Bureau produce a "Demographic Profile #1" this spring, for all places in the US? In spring 2001 (April/May/June, 2001), the Census Bureau produced a one-page profile based on Census 2000 short form data, kind of like highlights from the SF1 (not all of the details of SF1, data reported for places, counties, etc., not tracts, block groups or blocks.) This was an "intermediate" product between the release of the PL 94-171 files (February, March 2001) and the SF-1 files (summer 2001). Comment: One NEW table from the PL 94-171 is a housing units table (total, occupied, vacant units). This is great! This will allow city planners a very early opportunity to assess the quality of the short form data for their community. take care, Chuck Purvis Hayward, California

RE: [CTPP] Proposed Criteria and Guidelines for PUMAs responses are due FEB 28

by Elaine.Murakami＠dot.gov

Dear Everyone -- I am just re-iterating Mike's note. Some of the reasons that we want the transportation community to pay attention to PUMA criteria are: a. For Census 2000, the participation of transportation agencies in the PUMA delineation process was spotty, and therefore, the PUMAs defined in coordination with the CB's State Data Center program often were not useful for transportation planning, e.g. a county might be broken up into City A, City B and "rest of County" which looked like a cookie with 2 holes. The proposed criteria is to use census tracts and counties as the building blocks. b. PUMAs used to be primarily used with the Public Use Microdata Sample (PUMS), but PUMAs are now an important tabulation geography which meet the Census Bureau's threshold for annual reporting from the American Community Survey. Since counties and places often do not meet the 1-year threshold of 65,000 population, using PUMAs provides a geographic coverage without holes. I hope you will take this opportunity to provide your thoughts to the Census Bureau. And, when the actual delineation occurs, I hope that you will work together with your State's Data Center. http://www.census.gov/sdc/network.html Elaine Murakami FHWA Office of Planning 206-220-4460 -----Original Message----- From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of michael.r.ratcliffe(a)census.gov Sent: Monday, January 03, 2011 12:27 PM To: ctpp-news(a)chrispy.net Subject: [CTPP] Proposed Criteria and Guidelines for PUMAs for the 2010Census and the ACS Proposed Criteria and Guidelines for Public Use Microdata Areas (PUMAs) for the 2010 Census and the American Community Survey The Census Bureau announces publication of the "Proposed Public Use Microdata Area (PUMA) Criteria and Guidelines for the 2010 Census and American Community Survey" available on the Census Bureau’s website at http://www.census.gov/geo/puma/puma2010.html . The Census Bureau is seeking public comment on these proposed criteria and guidelines. Comments, suggestions, or recommendations regarding the criteria should be submitted in writing, no later than February 28, 2011 to Timothy Trainor, Chief, Geography Division, U.S. Census Bureau, Washington, DC 20233-7400. The Census Bureau's 2010 PUMAs will be used to present 2010 Census decennial Public Use Microdata Sample (PUMS) data, American Community Survey (ACS) PUMS data, and ACS estimates. PUMA delineations are subject to population threshold, specific building block geography, geographic nesting, and PUMA contiguity criteria. Proposed changes for 2010 PUMAs include: § Only one level of PUMA geography will be delineated (comparable to the 5-percent PUMAs for Census 2000). § Each PUMA must have a population of at least 100,000 persons at the time it is delineated, and must maintain a minimum population of 100,000 throughout the decade. § Each PUMA-county part must meet a minimum population threshold of 2,400 persons. § Counties and census tracts will be the only geographic “building blocks” for 2010 PUMAs. Additional information about the history of PUMAs, as well as summaries of the proposed changes are available on the Census Bureau's website at http://www.census.gov/geo/puma/puma2010.html . To obtain further information concerning the Census Bureau’s proposed 2010 PUMA criteria, please contact Vincent Osier, Chief, Geographic Standards and Criteria Branch, Geography Division, U.S. Census Bureau, via e-mail at vincent.osier(a)census.gov or by telephone at 301-763-3056.

[CTPP] American FactFinder2

by Jonathan Lupton

Thanks to everybody who offered tips yesterday. I'm glad I'm not the only one who is confused by FactFinder2. Let me share a few things I learned today as I prepared for my state's data release: 1. The Census Bureau is glad to help. The CTPP list serve put me in touch with somebody at the Bureau who did the kindness of offering help with factfinder2. Use the following numbers: Census training: 301-763-4308, or, if they're busy/overwhelmed with calls, you can call their call center at 800-923-8282. Apparently even the call center staff have the capability to walk you through factfinder2. 2. With Census Bureau help, I have done some cursory work in FactFinder2, and can bring down basic data, but not yet refined data. My summary opinion, after a half day of fiddling with it, as that with proper training FF2 is probably a marvelous tool, far superior to FF1. It allows you to create nice summary PDFs, and the download into Excel is smoother with less clutter. It will soon have the capability for downloading into other software types, and you can still go with the old standbys like .csv files. 3. The dark side, however, is that it can turn into a "hall of mirrors" pretty fast, as you dig for detailed data. I know where I'm going for a while, then suddenly something doesn't make sense, and I'm surrounded by apparitions that look real but are actually impenetrable reflecting walls. 4. A knowledgeable person candidly told me that he / she suspects the reason the SDC's haven't given much help so far is that they aren't yet fully confident with FF2 themselves, so they're not rushing to offer training in it. 5. The FTP process is also pretty daunting. My thanks to Mara Kaminowitz, who recommended downloading the FTP for one of the states that is already out, and practicing on it. I'm still struggling with Virginia, my chosen sample state; it's been a slog but I think I'm beginning to make sense of it. If you do the FTP download, don't forget to also download the related PDFs with instructions and background information. Again, thanks everybody for your help. As a data user, I find it comforting to know I'm not alone in these troubles! Jonathan Lupton Metroplan Little Rock, Arkansas

[CTPP] FactFinder2

by Jonathan Lupton

Is anybody else having trouble using FactFinder2? My state, Arkansas, is due for Census 2010 figures this week. I have tried to familiarize myself with FactFinder2, but cannot get much out of it. The actual product DOES NOT work the way the tutorial says it should. My agency will fall back on FTP downloading as our only source if necessary, of course. I hope we don't have to switch to FTP for everything! Our state data center had no help, nor any plans for training seminars, etc., when I called about this matter. Any tips, thoughts, reflections from other data users? Jonathan Lupton Metroplan Little Rock Arkansas

Re: [CTPP] RE: "Backing out" MOE

by Kevin Tierney

The Census Bureau suggests an approximation for calculating standard errors (MOE/1.645) for estimate differences (see link below). http://www.census.gov/acs/www/Downloads/data_documentation/Statistical_Test… The calculation for differences is the same as for aggregations (As Liang noted, the standard error increase whenever you combine estimates regardless of whether you are combining them or differencing them).

RE: [CTPP] "Backing out" MOE

by Liang.Long＠dot.gov

Hi, Louis To calculate the MPO for aggregated count data, you just take the square root of sum of the squared MOEs for each component estimate.

My question(s) is: If I sum up the estimates for all the municipalities in their respective county can I simply take the difference from the county total and call it the unincorporated part? If so, how do you obtain the MOE for this number? Can you "back out" the MOE from the adjusted (square root of the sum)muni MOEs and the county MOE?
