TCKs who have parents or guardians affiliated with the military have varying levels of exposure to local culture. This is due to the possibility of living on base or off base. TCKs who live off base or who are not closely affiliated with the military (such as contractors) will have higher exposure and cultural shaping, while those who spend the majority of their time on the base will have lower exposure and minimal cultural shaping.  Military children who are immersed in local culture from birth tend to show an extremely high level of cultural shaping, and upon relocation they are likely to cling to said culture for years, if not their lifetime. Relocation for these particular TCKs has shown to be particularly marring for them emotionally.  See also Military brat (. subculture) .
Throughout much of the twentieth century, the term "third sex" was a common descriptor for homosexuals and gender nonconformists, but after the gay liberation movements of the 1970s and a growing separation of the concepts of sexual orientation and gender identity , the term fell out of favor among LGBT communities and the wider public. With the renewed exploration of gender that feminism, the modern transgender movement and queer theory has fostered, some in the contemporary West have begun to describe themselves as a third sex again.  Other modern identities that cover similar ground include pangender , bigender , genderqueer , androgyne , intergender , "other gender" and "differently gendered".
