Data Services Knowledge Base: Access Questions

  1. I am at the Universityof Minnesota, Economics department. I am looking for the data on households income across sectors in the year 2003 in Russia. To be more precise, I need the data on low-income households employees compensation and high-income households employee compensation across sectors. If you have any idea what would be a good source, I would greatly appreciate it.
  2. I'm interested in looking at birth weight as a measure of child well-being. I can only find this in the Child Development Supplement (CDS), but this is only available from 1997 on.
  3. I’m interested in putting in two small grant proposals over the next few weeks – and both will be completely secondary data analysis – one of the data sets (MIDUS) is available through ICPSR and the other is the Wisconsin Longitudinal Study, which is publicly available. What is the UM policy on public use data and IRBs?
  4. Has anyone gotten clearance for the American's Changing Lives study, currently PI'd by Michigan researchers Jim House and Paula Lantz? We use the data because it's in-house, but if I wanted to put it in an R03 for October, would I need to go through IRB for approval?
  5. I am having trouble reading a file into SAS. SAS is complaining about the last variable in each record. If I look at it with an editor, it looks like a ^M.
  6. I am working with NELS data (base year, first follow-up and second follow-up). When I tried to extract the variables from raw data using the SAS setup cards provided by ICPSR, I do not get the right number of cases – way too few.
  7. I am doing an analysis with the PSID and I need a very simple variable – race. Where is the race variable?
  8. How do I read SAS export files?
  9. I want to compare the mobility of siblings in the PSID. How can I find siblings considering they no longer live in their family of origin?
  10. I can not find the 2000 version of the 1990 “School District Data book." I know that there is a 2000 version, since the National Center for Education Statistics has it on their website: [http://nces.ed.gov/surveys/sdds/index.aspx](http://nces.ed.gov/surveys/sdds/index.aspx) The NCES interface is extraordinarily cumbersome to use.
  11. I need data from several years of the March Current Population Survey but notice that these data do not have set-up files associated with them.
  12. Do you know if the summary files include information on the US protectorates in the Pacific (Guam, Marshall Islands, Samoa, Micronesia, etc.) and the Virgin Islands? I know the Census Bureau conducts a census in these locations.
  13. Is there a public use version of the ACS, similar to PUMS, with household data? Or just the interface where you get custom tables?
  14. Do you know anything about the National Longitudinal Mortality Study? I am interested in whether the cause of death (CAUSE) is available in the public use data.
  15. What level of geography do natality detail files go down to?
  16. How do I map a network drive? A restricted space has been set up for me on the network, but I cannot see it.

  18. I am having trouble opening an IMF government finance statistics data file.
  19. ICPSR has the Early Head Start Research and Evaluation (EHSRE) study but it only has the public use file. Where is the restricted version of the data and what are the access conditions?
  20. ICPSR used to have a FastTrack service where some data were released fairly immediately – before normal ICPSR processing. I cannot seem to find this anymore.
  21. I have found some estimates data on the Census Bureau website, but I have no idea how to look at it. Can you help me?
  22. I am interested to public use microdata from the Survey of Consumers. I would like it for as many years as possible. I do not know if the producers readily give this out but I know of researchers who have access to the data.
  23. I am confused about the different paths to access data and work areas at PSC.
  24. I am interested in creating some tables from the 2006 General Social Survey. It looks like ICPSR has the data. How easy is it to make a 4-way table – Political affiliation * Age * Education * Race/Ethnicity?
  25. The codebook for the 1972-2006 GSS does not agree with the data. The weight variables are noted as being in columns 6982-6993 and yet the data only goes to column 6801.
  26. I have some raw data without any set-up cards. Can you remind me how to read in data with stata?

  28. How does one get access to the Baccalaureate and Beyond data (public-use)?
  29. The Institute for Social Research (ISR) used to support Multiple Classification Analysis (MCA) through OSIRIS. I liked this program very much. Can you tell me if this is still available?
  30. How should I define my variables in Stata? Specifically, what are the options for character, integers and real numbers?
  31. I am working on a grant proposal with a colleague in the medical school. Her grants person told her that the restricted Add Health data requires a non-networked computer. Is this true? We would prefer NOT to have to include a computer in the budget if possible.
  32. I am using the IPUMS data and for 1970 the only file available is the 1970 metro, form 2. Is this a 1% file?
  33. I want to download the 2006 ACS microdata from the Census Bureau website as a stata file. Can you point me to the location where I can do this?

  35. I want to apply for the restricted version of PSID data (geocode). Can you clarify what sort of secure environment PSID requires.

  37. Can you remind me how to uncompress a file with a *.gz extension?
  38. I am trying to merge two files using SAS and I am getting a message that says "variable stcnty has been defined as both character and numeric." The merge did not work.
  39. I have some students working for me who are unfamiliar with statistical packages. Is there a way that they can pull off data for all census tracts in the tri-county area for Detroit? I have specific tables that I want for 1990 and 1980.

  45. The 2007 ACS data were released today. How long will it take for us to get the microdata?
  46. I am trying to merge a file with some restricted use items with the public use version of the data. I'm using stata. When I run the merge, I got a message saying "merge already defined." Is this because some of the variable names are the same?
  47. I have duplicate variable names in two data sets that I would like to merge using stata. Do I have to go through and change variable names?
  48. I have some health areas that are defined on the basis of census tracts. When I try to get race-specific results using summary file data from the census (2000) using American FactFinder, I find that some of my census tracts are missing. I know these tracts exist. What is going on?
  49. I need data for all zip codes in the nation. What is the easiest way to obtain characteristics on zip codes?
  50. I use NHGIS to get summary data from the census - not just historical data, but even the 2000 Census. However, when I try to get data for zip codes, I can only get data for one zip code at a time. Is there a solution for this?
  51. I am selecting census tract data for several counties within the US using American FactFinder. I am not able to find certain census tracts. For instance, for New York county, New York, I know there is a tract 197.01 and yet the highest tract number showing via American FactFinder is 99.
  52. Can one get data on Polish Americans from the census?
  53. I have a student who is trying to find time series physical capital stock from years more recent than are provided by the Penn World Table.

  59. A student of mine is interested in a survey called the Longitudinal Survey of Immigrants to Canada. Can you help her with access?

  66. We've had some interest on campus in developing a data archive for data generated by research performed by the college's students and faculty. We're working on developing procedures for migrating disclosure risk for human published guidance on what is an acceptable disclosure risk level. My statistical consultant informs me that it is mathematically impossible to get the disclosure risk (as measured by mu-Argus) down to 0, but nobody seems to be able to tell me what level of disclosure risk other archives consider appropriate , what level the U.S. government uses when preparing its microdata products, etc.
  67. Is the Master Address File that the Census Bureau uses for data collection public use or not?
  68. I have created a stata file, but when I click on it, it will not open. I can open it if I invoke stata and open it from stata, but I want to be able to click on it. What is the problem?
