The study reported in this document was a replication for 1971 high school graduates in New York City of a study on 1970 high school graduates in New York City. The purpose of the replication was to compare the characteristics and post-secondary school activities of the 1971 New York City high school graduates with those described for the 1970 graduates. Particular emphasis was placed on the examination of variables associated with college attendance, both at the City University of New York as well as other institutions. Student background variables investigated included type of high school attended, high school academic average, type of diploma received, family income, ethnic identification, and sex. The type of level of college in which students were enrolled were found to be related to the major background factors: public vocational students were more likely to enroll at CUNY; public vocational graduates were more likely to be enrolled in a CUNY 2-year college; students with lower averages were more likely to attend a 2-year college than a 4-year college; family income was related to variation in full-time college attendance; family income, high school grades, and ethnic identification were all found to be interrelated; and student choice of institution was directly related to income.
