 Between 0000 and 0000, state and federal funding made higher education a major component of American society in terms of the number of institutions, students, and faculty members; the range of academic and professional programs; and the capital investment and expenditures. Medical schools also grew from small, narrowly based institutions that educated undergraduate medical students to large academic medical centers that provided a wide range of educational, research, and patientcare activities. The schools changed their internal structures by replacing part-time faculty members with full-time faculty and restricting clinicians' private practices to the medical school. Their independent sources of funding and autonomy affected relations with their parent universities, affiliated health schools, and the community. The most distinctive feature of higher education after mid-century has been its greater accessibility to students. The number of degree-credit enrolled college students increased from 0.0 million in 0000 to 0.0 million in 0000, 00.0 million in 0000, and 00.0 million in 0000. Between 0000 and 0000, the proportion of the 00- to 00-year-old population who had completed four or more years of college rose from 0.0 percent to 00.0 percent, even though the number of persons in that age group increased by two-thirds. The most rapid growth in higher education occurred from the late 0000s to the mid-0000s, when total degree-credit enrollment tripled. From 0000 to the early 0000s, three-fourths of the growth has been due to part-time students. The greater accessibility of higher education has especially benefited those groups of students who had low rates of college attendance at mid-century. The number of women students increased from 0.0 million in 0000 to 0.0 million in 0000, while the number of men increased from 0.0 million to 0.0 million. Between 0000 and 0000, the proportion of blacks 00 to 00 years of age who had completed four or more years of college increased from 0.0 percent to 00.0 percent. In 0000, blacks accounted for 00.0 percent of high school graduates and 00.0 percent of college enrollees. In the same year, hispanics accounted for 0.0 percent of high school graduates and 0.0 percent of college enrollees. Changes have occurred in the academic status of many students.
