What is IPUMS?

IPUMS is the world’s largest publicly available population database, providing census and survey data from around the world integrated across time and space. IPUMS integration and documentation make it easy to study change, conduct comparative research, merge information across data types, and analyze individuals within family and community context. Data and services are available free of charge.

IPUMS consists of multiple projects, or collections, that provide different data products.

ipumsr supports different levels of functionality for each IPUMS project, as summarized in the table below.

ipumsr uses the IPUMS API to submit data requests, download data extracts, and get metadata, so the scope of functionality generally corresponds to that available via the API. As the IPUMS team extends the API to support more functionality for more projects, we aim to extend ipumsr capabilities accordingly.

Getting started

If you’re new to IPUMS data, learn more about what’s available through the IPUMS Projects Overview. Then, see vignette("ipums") for an overview of how to obtain IPUMS data.

The package vignettes are the best place to explore what ipumsr has to offer:

The IPUMS support website also houses many project-specific R-based training exercises. However, note that some of these exercises may not be be up to date with ipumsr’s current functionality.
