Data Type: Summary/Tabular Questions

  1. 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?
  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. I want to create an annual file with census-type characteristics of counties in California. What is the best source for this? This needs to be current, but I want it updated every year.
  5. When will new zip code data be made available?
  6. I am interested in creating a contextual file for counties, places, and MCDs form 1970 - 2000. What is the best source for this? I want my items to be measured the same over time. I cannot really determine the feasibility of this with Geolytics' Neighborhood Change database.
  7. 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.
  8. 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. Do you know if these data are available anywhere post-early 1990's? A search of the literature points to Nehru and Dhareshwar (1993) dataset, which can be found at http://go.worldbank.org/SR5689V6S0.
  9. Can one get data on Polish Americans from the census?
  10. How do I use American FactFinder?
  11. 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?
  12. I need data for all zip codes in the nation. What is the easiest way to obtain characteristics on zip codes?
  13. I am using a restricted data file that has zip codes for the geocode ID. I need to add some race-specific characteristics to the zip codes. However, zip codes are not iterated by race the way other geographies are (e.g., states, counties, census tracts). Is there a way around this?
  14. I have a student who is looking for annual data for each state on the party composition of their state legislatures, specifically the percent of Democrats in state legislative chamber.
  15. 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?
  16. 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?
  17. I am using data from selected zip codes in California for 1980 to 2000. How can I tell if the boundaries for these zip codes have remained the same?
  18. The 2007 ACS data were released today. How long will it take for us to get the microdata?
  19. What are the geographic areas available for the 2007 ACS?
  20. I need median household income for all zip codes in California. Where can I get access to this?
  21. Can I identify the lower 9th ward in New Orleans by zip code or census tracts?
  22. 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.
  23. I need many tables from the summary census data for 1990 at the census tract and block group level. I find American FactFinder difficult to use because I can only get data for a single tract at a time. I need all census tracts and block in Los Angeles county. Is there a better solution?
  24. Is there data for Washtenaw county in the ACS yet? How many counties in Michigan are available?
  25. I am looking for census data by gender on age, marital status, education, employment status, income, and race for congressional districts for each Congress from the 103rd to the 110th.
  26. Why do the counts from SF1 and SF3 differ?
  27. I have some census characteristics that I want to put into GIS. However, I am having trouble doing so because the FIPS codes in my data are represented as numbers; e.g., 1 for Alabama instead of 01. Likewise, Autauga county is represented as 1 instead of 001. I need an ID variable for Autauga county, Alabama that looks like 01001. How can I convert numeric data back to text in Excel? Right now, state is in one column and county is in the next column.
  28. I am generating some age-specific counts for various neighborhoods to compare with data in the Research Data Center (RDC). However, I am having trouble getting these counts to agree with what previous workers on this project have generated. Can you take a look at my numbers vs the project counts for our neighborhoods?
  29. I want to create a kml file using zip code data and boundaries. Can you point me in the right direction?
  30. I am considering using Geolytics Neighborhood Change Database for some longitudinal analyses that I am doing with death certificate data geocoded at the county level. However, I am a little unclear if the NCDB has info for nonmetro counties. The documentation is a bit confusing on this point. Could you advise?
  31. 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.
  32. I need national data from Summary File 3 from the 2000 Census. I need data at the county, census tract, and block level – summary levels 40, 140, and 150). This looks like a lot of files to download for just these summary levels. Is there a better solution?
  33. 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.
  34. 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.
  35. I need to know if there is a good source to look up 2000 PUMA geography via maps or lists. I need to get an idea of how different metros and counties line up with PUMAs.
