Subject : Population Characteristics Questions

  1. 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 was confused about the differences between different sheets in the 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?
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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?
  8. Can one get data on Polish Americans from the census?
  9. I need more information on IPUMS. Where can I find it?
  10. 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.
  11. 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?
  12. 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?
  13. I need an indicator of rurality for zip codes. Are you aware of something I could use?
  14. 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.
