Gender

Gender is the range of social, psychological, cultural, and behavioral aspects of being a man, woman, or third gender. Although gender often corresponds to sex, a transgender person may identify with a gender other than their sex assigned at birth. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other; those who are outside these groups may fall under the umbrella term non-binary. Some societies have third genders such as the hijras of South Asia and two-spirit persons native to North America. Most scholars agree that gender is a central characteristic for social organization; this may include social constructs as well as gender expression. Read more on Wikipedia
