In the early 1920s, a group of scholars set out to make a complete investigation of economic, religious, educational, civic, biological, and social conditions among the Chinese, Japanese, and other non-white residents of the Pacific Coast of the United States and Canada. Extension of the study into northern Mexico and Hawaii was contemplated as well.
The original records, including a report, correspondence, interview transcripts, questionnaires, and printed matter, are housed at the Hoover Institution Archives. The entire collection was digitized and is available online through a collaborative agreement with Stanford University Libraries.
