This report is based on a questionnaire survey sent to the registrars of all two-year and four-year colleges and universities in the United States. Replies were received from 2,637 institutions, of which 2,374 reported registrations in one or more foreign languages. The fall 1977 survey shows a decline of 1.4% in total foreign language registrations between 1974, the year of the last previous survey conducted by the Modern Language Association, and 1977. Registrations declined by more than ten percent in German and Russian, but by three percent or less in French, Latin, and the aggregate of the so-called "other" or less-commonly taught languages. Spanish continued to be the leading language in U.S. colleges and universities, accounting for 46% of the total. The report consists of an introduction, six summary tables, fourteen detailed tables, and the report form used in the survey. The detailed tables present data by state or by region for the seven most commonly taught languages and for the "other" languages as a block, as well as detailed comparative figures from surveys undertaken in 1968, 1970, 1972, 1974, and 1977.
