Psychologists carefully separate biological characteristics from social, psychological, and romantic dimensions of identity.

| Gender identity | A person’s deeply felt internal sense of being male, female, neither, or a blend | A core aspect of identity development that may match one’s sex assigned at birth or differ from it (e.g., transgender or nonbinary). |
