* Discontinued in 2007 because CPS now measures cohabitation directly.

"1/ Prior to 2007, estimates of unmarried partners of the opposite sex were "
included restricted to couples where one of the partners was the householder.  
"In 2007, all opposite sex unmarried couples are included, regardless of "
householder status.

"2/ In 2007, unmarried couples of the opposite sex with children under 18 years "
were in the estimates if either partner had at least one never married 
biological child under 18 living with them.  

3/  These estimates of unmarried couples (Partners of Opposite Sex Sharing 
Living Quarters) include households that have two unmarried adults
of the opposite sex.  They may or may not have identified themselves
as unmarried partners of the householder.
