Data Type: Counts 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 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?
  3. Can you help me with historical data on rates of homicide and aggravated assault for the 1940s and 1950s for large American cities?
  4. 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.
  5. Can you help me find the University of Michigan Inflation Expectation Survey?
  6. I am looking for the size of the 18-19 year old population in the US over time. This must be available from the Census Bureau but I am not finding anything.
  7. 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?
  8. I need time series data on attitudes in New York City from 1999 to the present.
  9. Can you please give me an estimate of the 2006 size of the baby boomer cohort (born 1946 to 1964)?
