(POSSLQ, an acronym for "Persons of Opposite Sex Sharing Living Quarters," was used in the late 1970s by the U. Census.)

"People feel a real need for a term that refers to one's romantic partner that does not sound childish," says Jesse Sheidlower of Manhattan, editor at large of the Oxford English Dictionary. More than 30 million live alone, making up 27% of all households; that's up from 17% of all households in 1970. One member of a couple is alone after a spouse dies.
