"This Field Guide was prepared by Denice W. Ross and Christopher Steven Marcum with support from the UC Berkeley Executive Fellowship in Applied Technology Policy.

"The Guide is organized into eight primary categories of federal data (described on the right), each representing distinct collection methods, policy frameworks, and use cases.

"This field guide focuses primarily on publicly available datasets created, maintained, and published by executive branch agencies of the federal government. This Guide does not include sensitive or classified datasets, or derivative works such as reports or interactive web tools that use data.

"The purpose of this guide is to provide a more complete context for federal data users and stakeholders that will inspire them to consider a broader range of data types in their research and advocacy; we also hope it will also inform national dialogues about the future of federal data.

"Denice W. Ross is a Berkeley Executive Fellow in Applied Technology Policy and served as the nationʼs second U.S. Chief Data Scientist. Christopher Steven Marcum, Ph.D. is an expert on statistical and scientific data who served as Assistant Director for Open Science and Data Policy at the White House OSTP."
