Birth Order and Sex of Siblings in a Sample of Lesbians and Non-Lesbians

Abstract

Data from 217 Lesbians and 231 non-Lesbians, displaying birth order among male and female siblings, reveal proportionately more Lesbians who are “only” or first-born of two siblings or who are fifth, sixth, or seventh in such large families; and fewer Lesbians among third child of three-sibling families.
