Research on Health Disparities: Incarceration Matters

Data Services Knowledge Base: Subject Questions

  1. I am trying to some mortality data for the state of Michigan and Montcalm county, Michigan from 1960 to present. We’d prefer age-adjusted figures over age-specific. Do you have any thoughts on how best to obtain these data? This is for a health disparities documentary and the data are needed immediately.
  2. I'm writing to see if you know how I can obtain a variable that indicates the "urbanicity" (a binary "urban" versus "rural" variable would be fine) of all U.S. counties. This variable should be fairly recent (around 2000 is good). I thought it would be easy to track down on the web but haven't had luck.
  3. Has anyone combined the 1999-2002 data with the 2003-2004 NHANES data? I'm using the 4yr weights for the 99-02 but I'm not sure what to do with the 2yr weights on the 2003-2004 data - there don't appear to be updates with 6yr weights. How do I handle the weights when combining 03-04 with the earlier data?
  4. I was looking at the variables in the Collaborative Psychiatric Epidemiology Surveys (CPES) and I need to know how pregnant women are identified in the surveys. Also, how many pregnant women are in the samples?
  5. Do you know if the 1960 census asks the same ‘where did you live 5 years ago’ question that was asked in 1970-2000?
  6. 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.
  7. 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?
  8. 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?
  9. How is the residence of prisoners noted on death certificates - the prison or the original home address? What about other institutional populations (dorms, hospitals, etc.)?
  10. What data allows one to tell the extent of divorce on family structure? What I mean is that lots of children live in a two parent family, but it is often a blended family, not the original set of biological parents. I want a count of the number of kids in the following living arrangements: (a) single parent; (b) married couple, with only one biological parent; (c) married couple, with both biological parents; (d) not living with either biological parent.
  11. Can one look at fertility in the American Community Survey (ACS)? Is there a children ever born question?
  12. Do you know of a source of vital statistics data for the United Kingdom and Canada? My ideal data would be single years of age and cause of death for many years.
  13. I need a longitudinal data file that has multiple measures of blood pressure. The sample should include women of all races.
  14. I am using the "Immigrants Admitted to the US" files and would like to compare my results with the statistical yearbooks that the Immigration and Naturalization service produced. I'm not finding these on the INS website.
  15. Is there a way to get a count of the number of single women over 40 who moved in the past year?
  16. I need an indicator of rurality for zip codes. Are you aware of something I could use?
  17. Where can a user find GIS information concerning HIV rates?
  18. I need to know some characteristics of the Korean population in the United States. Is there a search term I can use to find information or do I have to come in and learn how to use the data?
  19. I have a student looking to measure the geographic dispersion of families (at least in the U.S., and other places if possible), specifically: 1) how many families with children at home have grandparents who are out of state and 2) how many divorced parents with children at home are not co-located in the same state (e.g., child lives with one parent and the other is out of state or child spends time with each parent in separate states)." There seem to be lots of measures of an individual household's mobility (from the U.S. Census and CPS per se), and the U.S. Census even has a measure of grandparents living in the same household with children. Do you know of any nationally representative data that will fit the bill?
  20. 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?
  21. Do you know of a source for segregation indices that cover the 1970 to 2000 time period? I want this to be for metropolitan areas and for the measure to be a white vs black index.
  22. Can one get data on Polish Americans from the census?
  23. Where can I find data on exact dates of death?
  24. 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?
  25. 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.
  26. I am pulling race-specific county level data from the 1990 summary file data. I have to use the original summary files because neither American FactFinder or NHGIS iterate characteristics across all the race groups I need. However, I am getting strange results. I get multiple records for my counties.
  27. I need more information on IPUMS. Where can I find it?
  28. Does anyone know if the Guatemalan national surveys data are freely available, or have experience acquiring this data? The Guatemalan government seems to make only the most recent year's available online.
  29. 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.
  30. Do you have a source for the number of undocumented migrants by state from 2000 on?
  31. Do you know of a source for data on Southern Cities before World War II? I want to look at racial residential segregation during the interwar period in Houston, Little Rock, Atlanta and Raleigh. I do not want to rely on ward data, since the size, shape, and number of wards within each city changed often during this period.
  32. I need historical data on life expectancy and child outcomes for Nepal and how this compares to the US historically. In other words, when did the US look like Nepal in 1970?
  33. Is there any source that reports percent of rural population in the USA by race (1965-2010)?
  34. I recently downloaded the excel files [Median Household Income and Mean Household Income [2006-2010]](http://www.psc.isr.umich.edu/dis/census/Features/tract2zip/index.html). I found it very useful to know the these statistics by zip code but I was confused about the difference between different sheets in the excel file. For example, the median incomes on the "national" sheet don't match up with the median incomes on the "median" sheet. Is there a mistake, or do I not understand what the data means? Is there somewhere I should go to learn more about how the statistics were calculated?
