Data Type: Census/CPS Questions

  1. I am examining the relationship between metropolitan-level foreclosure and racial residential segregation in U.S. American cities between 1990 and 2010. I am including characteristics which can be found in decennial census surveys and ACS estimates. One variable absent from these sources is the age in which the largest city in the metro reached a population size of 50,000. I was curious to know of any source that has already compiled this.
  2. I have funny results for the distribution of education using 1950 IPUMS data. What am I doing wrong?
  3. What is up with the allocation item for earnings in the March CPS? It drops from a reasonable 22% to around 2% between 1987 and 1988. I am using data from IPUMS-CPS (qincwage).
  4. Can one interpolate between the 2000 and 5-year ACS (2005-2009) to get characteristics of census tracts? In other words, can the 5-year data be thought of as a snapshot for 2010?
  5. I need a table of poverty status and tenure for Washtenaw and Wayne Counties. However, I am defining the poor population as below 2x of the poverty line rather than the normal cutpoint.
  6. Is the Master Address File that the Census Bureau uses for data collection public use or not?
  7. What does data defined person mean? It is an item in the microdata for 2000.
  8. How can an intercensal estimate change? I have an estimate from a P-25 report for July 1, 1977 and it does not agree with what is on the Census Bureau estimation web site.
  9. What is the difference between OCCSOC and OCCCEN in the 2000 census (and the ACS)?
  10. I have run into an ArcMap mxd file that has a cell that I am interested in joining to that is defined as 'string'. This is happening in the counties template within my ArcGIS version 9. The cell has a 5 digit value representing a state and county mixed FIPS code (i.e. 26183 ) How do I go about converting the cell to a numeric one?
  11. I am interested in using the "housework" question in the Canadian census. IPUMS-i has the data, but it looks like they left out that variable.
  12. Do you have a quick way to access the Current Population Surveys (March supplements) prior to 1992? I am trying to get a small extract from each year, but the DataFerrett access only lets me go back to 1992.
  13. What proportion of American Community Survey (ACS) interviews end up in the ACS microdata samples?
  14. I am interested in the examining the American Indian populations. Do you have an idea if the ACS includes American Indians, on and off the researvations?
  15. How do I concatenate two files in SAS?
  16. We were wondering if you might know of a center or individual on campus with the 2001 Canadian Census Public Use Sample. It does not appear that ICPSR has it, and Statistics Canada only appears to offer it for a fee. We might also be interested in looking at the 1996 data.
  17. Can one get data on Polish Americans from the census?
  18. How do I use American FactFinder?
  19. What types of institutions are considered "group quarters" in the 2006 ACS? How will the inclusion of GQ affect comparisons with previous ACS?
  20. What are the sizes of the geographic units for the 2007 ACS and how are they determined?
  21. How do you create county level data using microdata files?
  22. What are the sizes of the geographic units for the 2006 ACS and how are they determined?
  23. I need more information on IPUMS. Where can I find it?
  24. How can I make a map without having special software?
  25. Where can I find out more information on the quality of the data used in the American Community Survey?
  26. 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?
  27. I need data for all zip codes in the nation. What is the easiest way to obtain characteristics on zip codes?
  28. I have a student who is interested in post-retirement employment patterns and determinants. She is very interested in looking at trends in the experience and correlates of post-retirement employment. We are thinking about using the CPS and taking advantage of the "month in sample" variables to construct some short longitudinal files so that we can estimate the prevalence and determinants of returning to work after retirement. So here are my questions: 1. If a respondent reports being retired at time t, are they asked questions about employment in subsequent interviews? 2. Do you know of any technical bulletins or such information that lays out exactly how to link respondents across the their multiple interviews?
  29. I am using data from the American Community Survey (ACS) for Monroe and Lenawee counties in Michigan. The tables from American Factfinder have margins of error for all the cells. However, if I am combining the two counties is there a way to calculate new margins of error based on this larger population?
  30. I want to combine the 2005 and 2006 ACS microdata. What do I do to the weights?
  31. I need median household income for all zip codes in California. Where can I get access to this?
  32. I have a neighborhood that I define by census tracts. How can I create characteristics for these neighborhoods in SAS
  33. I am trying to match data for 2006 and 2007 from the March CPS so that I can track respondents across the two years. I downloaded the NBER matching files, but they don't seem relevant to data this recent. I also read the information about matching in the CPS codebook, but it's not clear to me how to operationalize their suggestions. Would it be possible to get some assistance with this issue?
  34. Is there a way to get a count of the number of single women over 40 who moved in the past year?
  35. Is there data for Washtenaw county in the ACS yet? How many counties in Michigan are available?
  36. Does the American Community Survey (ACS) have data for zip codes?
  37. I want to combine two years of the March CPS to compare with data from a survey that took place over a two-year period. The survey took place in 1994 and 1995.
  38. I have looked at census data on commuting patterns, but there is no information on the characteristics of the commuters. How can I get data on commuters? I am interested in the townships surrounding Philadelphia. I also need maps that show townships for Pennsylvania. I'd like the maps to include major roads.
  39. 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?
  40. I am using the IPUMS data and for 1970 the only file available is the 1970 metro, form 2. Is this a 1% file?
  41. Why do the counts from SF1 and SF3 differ?
  42. I am trying to get a sense of the American Community Survey (ACS). It is harder than I would have thought. Am I correct in thinking that annually they survey approximately 3,000K households per year? Are the samples independent of each other - e.g., 2005 and 2006? Finally, they do not seem to ask about country of birth. This seems odd although you might be able to make an estimate with ancestry and citizenship.
  43. The Pew Hispanic Center put out a report last November with Race, age and citizenship status info from the September 2007 CPS. (See table below from report): [http://pewhispanic.org/files/reports/83.pdf](http://pewhispanic.org/files/reports/83.pdf) I didn’t know you could get race info from anything other than the March CPS. What do you know about race information available for other months?
  44. Why are there zero weights in the 1990 public use microdata file for the U.S. census?
  45. I am using microdata from the 2000 Census of Population and Housing. I have found some families with a code of "0" on family income. Is this an error on the part of the Census Bureau? If not, what is the explanation?
  46. Is there a public use version of the ACS, similar to PUMS, with household data? Or just the interface where you get custom tables?
  47. 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.
  48. 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.
  49. Do you know if there is a way to construct a Hispanic measure in the 1960 PUMS? I assume by the 1970 census there is a Hispanic category. Is that right?
  50. Do you know where I can find a list of the variables that are available in the summary files for the 2000 census down to the block level? I should know the answer to this by now.
  51. Do you know if the 1960 census asks the same ‘where did you live 5 years ago’ question that was asked in 1970-2000?
  52. I would like to get a copy of the Census 1990 elderly households 8% sample dataset and codebook. Please let me know if it is available and the procedure for obtaining it.
  53. Is there a document or documents that compares occupation codings in the census over time . . . say 1960-2000?
  54. I downloaded a US Census Extract recently and have been running some descriptive statistics. In terms of race, Brazilian median household income immigrants mostly identify as white, "some other race" and "two or more races". I would like to find out how they classified in the latter 2 categories. Is there any way I can do this? Also, if it is just a matter of creating an extract with specific variables (e.g. "OTHER", NUMRACE), would it be possible to add these variables to my existing dataset? Or would I need to do a completely new data extract with all of the variables?
  55. Can you please give me an estimate of the 2006 size of the baby boomer cohort (born 1946 to 1964)?
  56. I am unsure how to merge geographic data to a file that I have. I noticed that the census tract numbers do not stand alone in the data file that I downloaded from the census and that the GEO variable is saved as a text variable so I am unable to merge my data sets using that variable. Would you be willing to show me how to link these two data sets if all I have is the census tract number?
