The U.S. Census Bureau provides local, state and national statistics relating to poverty, educational attainment, overcrowded housing, single parent families, grandparents raising grandchildren, etc. Much of the data can be "cross-tabulated" by another variable such as race/ethnicity, gender, immigrant status, language or age. American FactFinder is a good entry point.

LexisNexis Statistical and LexisNexis Statistical Datasets can also help find a wide range of statistics.
While there is a wealth of statistical information available nowadays, finding a particular set of statistics is not as easy as one might believe. Key questions to consider are whether statistics on the particular issue are collected, who collects them, and how they are organized. For help in identifying relevant statistics and data sets, please contact the reference librarians.
The Library also maintains a data lab in 208A Doe Library. The Data Labprovides access to a growing collection of electronic data files and analytical software, such as MS Excel, SAS, SPSS, Stata, and DataFerret. Staff will help you locate, retrieve and use computer-readable, numeric data.
