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.

Software with built-in mapping capabilities that create thematic maps for instant spatial display of census demographic information.

The NHGIS specifically provides spatially aggregated census data: data summarizing individuals within particular areas, such as states or counties, where the "individuals" might be persons, housing units, farms, libraries, newspapers or any other features that were at some point counted in a U.S. census. No individual-level records, with or without personally identifiable information, are included anywhere in the NHGIS.
