The Roper Center for Public Opinion Research is one of the world's leading archives of social science data, specializing in data from surveys of public opinion. The data range from the 1930s, when survey research was in its infancy, to the present. On the Roper iPOLL page, you can search with keywords or filter by country, organization, etc.

Working with Numbers
When working with statistics, aggregate data, and microdata, it is important for you to consider the following:
- Context - what is the hypothesis, e.g. "middle income people are more likely to register and vote than lower income".
- Geography - the US, county, city, neighborhood, congressional district
- Time Period - current, historical, over time,
- Population/Units of Analysis - age, sex, race, ancestry, educational attainment/households, individuals
- Variables - observations or item of data for each unit of analysis; responses to questionnaire and how they are organized
- Questionnaire - what questions were asked; shows what will and won't be available in the data
- Source of the Data - is it publicly available from a government source or collected and produced by a company for profit?
Not sure what these and other statistical terms are? Check out the Glossary of Selected Computing and Social Science Data Terms by Jim A. Jacobs.
