This statistical handbook describes the growth in numbers of doctorates granted in various fields and corresponding growth in numbers of colleges and universities; delineates patterns of doctoral education in the US and shows changes that occur in transition from academic to professional work; describes US doctorate recipients of foreign origin and women doctorate recipients; and provides extensive institutional data in the appendices. The source of the data is the Doctorate Records File, a repository of information from the annual Survey of Earned Doctorates distributed to graduating PhDs. The primary purpose of the report is to present useful data describing recent trends in US doctoral education. Little interpretive comment is included but "care has been taken to make the tables and figures as clear and self-explanatory as possible." (JS)
