Gender

Gender is the range of social, psychological, cultural, and behavioral aspects of being a man, woman, or other gender identity. Depending on the context, this may include sex-based social constructs (i.e. gender roles) as well as gender expression. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other (girls/women and boys/men); those who are outside these groups may fall under the umbrella term ''non-binary''. A number of societies have specific genders besides "man" and "woman," such as the hijras of South Asia and Two-spirit Indigenous Peoples of North America; these are often referred to as ''third genders'' (and ''fourth genders'', etc.). Most scholars agree that gender is a central characteristic for social organization.

The word is also used as a synonym for sex, and the balance between these usages has shifted over time. In the mid-20th century, a terminological distinction in modern English (known as the sex and gender distinction) between biological ''sex'' and ''gender'' began to develop in the academic areas of psychology, sociology, sexology, and feminism. Before the mid-20th century, it was uncommon to use the word ''gender'' to refer to anything but grammatical categories. In the West, in the 1970s, feminist theory embraced the concept of a distinction between biological sex and the social construct of gender. The distinction between gender and sex is made by most contemporary social scientists in Western countries, behavioral scientists and biologists, many legal systems and government bodies, and intergovernmental agencies such as the WHO. The experiences of intersex people also testify to the complexity of sex and gender; female, male, and other gender identities are experienced across the many divergences of sexual difference.

The social sciences have a branch devoted to gender studies. Other sciences, such as psychology, sociology, sexology, and neuroscience, are interested in the subject. The social sciences sometimes approach gender as a social construct, and gender studies particularly does, while research in the natural sciences investigates whether biological differences in females and males influence the development of gender in humans; both inform the debate about how far biological differences influence the formation of gender identity and gendered behavior. Biopsychosocial approaches to gender include biological, psychological, and social/cultural aspects. Provided by Wikipedia
