Consensual union pairs will be counted as those pairs that live within the same household and declare themselves mutually as conjugates/partners and the marital status (de jure) of at least one of the two people is that of not married.

As it has already been mentioned that marital status is used as a variable of the processes of the formation of nuclear families correlated with fertility. However, these family formation processes are increasingly based on unions outside of matrimony.

This variable also indicates whether or not, independently of marital status, the individual lives with a partner or not.
