Data Ferret
To access the ACS Public Use Microdata you must download the DataFerrett application or applet. DataFerrett is a data analysis tool with the ability to access many federal, state, local, and private datasets via an internet connection. It can be installed as a stand alone application or be used through an internet browser as a java applet. Users who go through a proxy server on their network might find more success using the applet version than the application version. It is highly recommended that you go through the DataFerrett tutorial before using DataFerrett.

IPUMS (Integrated Public Use Microdata Series)
The Integrated Public Use Microdata Series (IPUMS-USA) consists of more than fifty high-precision samples of the American population drawn from fifteen federal censuses and from the American Community Surveys of 2000-2007. Some of these samples have existed for years, and others were created specifically for this database. These samples, which draw on every surviving census from 1850-2000, and the 2000-2007 ACS samples, collectively constitute our richest source of quantitative information on long-term changes in the American population. However, because different investigators created these samples at different times, they employed a wide variety of record layouts, coding schemes, and documentation. This has complicated efforts to use them to study change over time. The IPUMS assigns uniform codes across all the samples and brings relevant documentation into a coherent form to facilitate analysis of social and economic change. IPUMS is not a collection of compiled statistics; it is composed of microdata. Each record is a person, with all characteristics numerically coded. In most samples persons are organized into households, making it possible to study the characteristics of people in the context of their families or other co-residents. Because the data are individuals and not tables, researchers must use a statistical package to analyze the millions of records in the database. A data extraction system enables users to select only the samples and variables they require
