Nandu is right. Employed persons is anybody who is a civilian with a job. Workers are anybody with a job who was at the job during the reference week (not sick or on vacation.) Our workers also includes military workers at domestic bases who were at work during the reference week. |---------+-------------------------------> | | "Srinivasan, Nanda" | | | <Nanda.Srinivasan@fh| | | wa.dot.gov> | | | Sent by: | | | owner-ctpp-news@chri| | | spy.net | | | | | | | | | 03/06/2003 12:32 PM | | | | |---------+-------------------------------> >-------------------------------------------------------------------------------------------------------------------------------| | | | To: "hubsmtp.gwhub.\"vputta(a)incog.org\"" <IMCEAGWISE-hubsmtp+2Egwhub+2E+22vputta+40incog+2Eorg+22(a)fhwa.dot.gov>, | | <ctpp-news(a)chrispy.net> | | cc: | | Subject: RE: [CTPP] new data release? | >-------------------------------------------------------------------------------------------------------------------------------| Viplav, Here's an attempt to answer your question. Phil Salopek or anyone else can correct me if I am wrong. There are two reasons I can think of for the differences you have noted: 1. Total employed vs total workers. and 2. Workers WORKING in Tulsa MSA vs Workers LIVING in Tulsa MSA 1. Total employed vs total workers. I hope the numbers you have given me are the totals for WORKERS from SF 3 and the county-county worker flow files. If you picked employment status, then you could be off. The data on employment status are derived from questions 21 and 25 of the "long form." "Employed" is defined as all persons 16 years or older who were: a. at work. b.with a job but not at work. The CB considers the terms "employed" and "civilian employed" as exactly the same. People who volunteered to work (without pay), and people who worked for the armed forces are excluded from "Employed." "Workers", as used in Journey-to-work and CTPP, on the other hand, refers to: a.All those people 16 years or over who were AT WORK in the reference week. b.All people employed in the Armed Forces. 2. Workers WORKING in Tulsa MSA vs Workers LIVING in Tulsa MSA I hope you are comparing the number of workers LIVING in Tulsa MSA with the SF 3 results. If you totaled the commuter flow INTO Tulsa, you may have a difference between that and the total workers LIVING in Tulsa. If you are comparing County-County worker flows with SF3, please total the workers residing in Tulsa from the county-county worker flow table, and then compare the number to a table from SF3 that contains WORKERS (Eg: mode to work including worked at home). The numbers should be pretty close. CB corrected some errors in worker flows for some areas, but Tulsa is not one of those, per Phil. Thank you!

Thanks Nanda for the link. I just have one question though: The data is for Commuting to work employees in each county. Total employees who reported as commuters to work does not equal the total number employed in respective counties. Is this because of estimates resulting from sampling?

Welcome to the world of data embargo! The press are usually issued the information early so they have time to research and write their stories. Unfortunately, those of us who are supposedly "in the know" haven't gotten the embargoed information. As such, they call us for information and we end-up getting it from the press! I've been in this position for the last 15 years, so I've "been there, done that". Any Bureau folks like to clarify? Michael D.

FW: [CTPP] new data release?

by Foster, Paul

My understanding is that the Census Bureau recognized State Data Center's can grant access to embargoed data to their affiliates once those affiliates have completed paperwork certifying that they understand and will comply with Census Bureau embargo policy. I have been able to access the County-to-County workflow data and was given a username and password to the embargo site through the Massachusetts State Data Center of which our organization is an affiliate. This may be handled differently by different states. There is a list of State Data Center websites under the network tab of the following website: www.sdcbidc.iupui.edu. This was also true with the embargo period for Census Summary File 3 releases in Fall 2002. Paul Paul N.

Why Embargo?

by MGolembiewski＠mail.countyofberks.com

As a 15-year veteran of the State Data Center Affiliate program here in Pensylvania, I have some experience with these issues. Embargoed data were, at one time, issued to the media and State Data Centers for their respective uses prior to the general 'public' releases. It was up to the State Data Centers to then issue the data to their affiliates. Here in Pennsylvania, we (SDC Affiliates) used to have access to all embargoed information. Unfortunately, throughout the nation and prior to Census 2000, some states and many affiliates routinely broke the embargoes. The Census Bureau has never had a sense of humor about this and, subsequently, revoked embargo rights to many state agencies and non-press people. This has resulted in the situation many of us are facing this afternoon. Since Census 2000, State Data Centers have been given rights to embargoed data, but it is up to individual Data Centers as to whether they will release the data to their affiliate agencies. I know that, in New Jersey, those affiliates have access; here in PA, we do not. If you're not familiar with the State Data Center program in your state, the Census Bureau website has information and links. Any Bureau comments? Michael D.

RE: [CTPP] Embargo or Not to Embargo

by Marion, Christine

As I had responded to a fellow county planner in Berks County, PA, I believe it is your relationship with your State Data Center and their relationship with the Census Bureau that is affecting your access to Census data. After signing an agreement with the State not to release the data during the embargo period, our county received the NJ County to County Data from our State Data Center on Monday. Not all the data, but at least the information we need to respond to questions from the press. Why embargo the information? To give those in office time to analyze the information in order to be able to respond to any questions. The same questions of course, that are asked of demographers and planners working for government. It also gives the Senators and Congressmen and women a chance to look at the data before anyone else. -----Original Message----- From: Bob Paddock [mailto:bob.paddock@METC.STATE.MN.US] Sent: Wednesday, March 05, 2003 12:37 PM To: ctpp-news(a)chrispy.net Subject: [CTPP] Embargo or Not to Embargo I have to laugh at the spate of comments concerning the embargo of census information.

Thank you! But what is the rationale for this policy? >>> <MGolembiewski(a)mail.countyofberks.com> 03/05/03 11:24AM >>> 'Embargoed' data means that it is released to a select group at a certain date/time, but is specifically not allowed to be distributed or published until a later specified date/time.
