Re: [CTPP] UPDATE 2010 Census Block-Level Data is Changed SF1-P1

by Geoff Olson

The values match one those "(rXXXXX)" parts are removed. I called Census this morning and they informed me that those are footnotes for values that have been revised due to a CQR. I thought that all CQR data was kept separate and I'm not quite sure why it has to be in the same field as the count value and not a separate field. So the important thing to know is that the text file that's included with the downloaded data shows those footnotes and their corrected counts. All those footnotes must be removed from the cell before that data can be used. Thank you, Geoff Olson Transportation Planner Bi-State Regional Commission 1504 3rd Ave. P.O.

We've done various checks between the two tables (SF1-P1), and the sums are different. Our MPA population count with the older data is 297,986 and the sum the new data is showing us is 297,290. We did check this with ESRI's Community Analyst and it agrees with the older data that our MPA should have a Census 2010 population of 297,986. Is there a reason when Census data might change?

Re: [CTPP] female daytime population

by Liang.Long.CTR＠dot.gov

Hi, Bob LODES Does not include self-employed (approx. 10% of workers). We have done some comparisons among LEHD, ACS and CPS in terms of employment data. Here is the link: Please go to the third article: Counting Workers: Comparison of Employment Data for CPS, ACS and LODES http://www.fhwa.dot.gov/planning/census_issues/ctpp/status_report/sr100113.… There is also another article of “Comparing Commuting Flows between CTPP and LODES” http://www.fhwa.dot.gov/planning/census_issues/ctpp/status_report/sr1213.pdf But I never got a chance to investigate employment by age and gender using LODES. ACS PUMS data are good source if you are looking for employment information by age and gender as they provide ages in one year increment. Also, some of the employment status questions were modified in 2008, resulting in ACS employment estimates which are better matched with the CPS labor force estimates. But of course, you can only get this information down to PUMA level (100,000 population thresholds). Hope this helps.

The WAC data appears to have both some age group stratifications and gender. I meant to ask about the use of the LEHD data as a question to see how it compares with the CTPP/ACS approach. With previous experience we have found that the gender fields do not sum to the total employment values, so there is missing data in the LEHD also. But, could it be a more complete dataset and could it give a better estimate? Has anyone else checked this for other areas? Also, although the age groups are 29 and younger, 30 to 54, and 54 and older, could it be assumed that most of the employees, even in the 29 and younger age group could be classified as "adult" ?

Re: [CTPP] female daytime population

by Robert Shull

Thanks Ed and Liang, I had understood that Steve was trying to get adult "daytime" female population by census tract. The WAC data appears to have both some age group stratifications and gender. I meant to ask about the use of the LEHD data as a question to see how it compares with the CTPP/ACS approach. With previous experience we have found that the gender fields do not sum to the total employment values, so there is missing data in the LEHD also. But, could it be a more complete dataset and could it give a better estimate? Has anyone else checked this for other areas? Also, although the age groups are 29 and younger, 30 to 54, and 54 and older, could it be assumed that most of the employees, even in the 29 and younger age group could be classified as "adult" ? Thanks!

Re: [CTPP] female daytime population

by Ed Christopher

Lehd now has age and sex for data in the 2009 to 2001 series. http://lehd.ces.census.gov/data/lodes/LODES7/LODESTechDoc7.0.pdf "Datasets for 2009-2011 contain additional variables (Race, Ethnicity, Education, and Sex) on the Residence file (RAC) and Workplace (WAC) files that are not available in other years of data. And datasets for 2011 contain further additional variables (Firm Age and Firm Size) on the WAC files." I haven't looked at any of this or played with it but it could be promising.
