@my3sonshines: If you look at the UNC-CH Common Data Set, here, https://oira.unc.edu/files/2017/07/cds_2016_2017_20170411.pdf, part C1 gives you the number of males vs. females in the most recent applicant class for which these numbers have been compiled. Females were about 59% of the total applicant pool, and the same percentage rate for admitted students as well. Section B1 of the CDS gives the male/female breakdown for the overall undergraduate population, which is also about 59% female.
