The survey, conducted annually for the past eight years by the Journal of Blacks in Higher Education, stated that black students made up 12 percent of the University's freshman class this year.
UNC Undergraduate Admissions Director Jerome Lucido said the high percentage of black students is the result of the University's efforts to recruit minority students.
"There has been a real strong teamwork approach from the Office of Minority Affairs and Undergraduate Admissions as well as student groups," Lucido said. "(These groups) have pulled together to do a real comprehensive job of recruiting."
He also said the University has achieved a positive reputation among black students.
"There is a greater sense of confidence in this institution among black students and their families," he said. "The University has done a good job of creating a welcome climate."
Lucido said this is not the case at some universities where race relations are more strained than at UNC.
Lucido said UNC received 2,100 applications from black students last year, the highest number to date. But he said the University is still looking to increase the representation from all minority groups, especially Native Americans.
Duke University ranked second with black students constituting 10.5 percent of the student population. The University of Virginia ranked third in the survey, with 10.2 percent black enrollment.
Larry Groves, associate dean of admissions for UVa., attributed the university's high numbers to the school's ability to appeal to black students.
