Long term I think this is going to be huge politically, between the aging of the boomers and the other changes (people not getting married but living together and having kids). What the impact is I am not sure...
Today's Washington Post reports that "married couples with children now occupy fewer than one in every four households -- a share that has been slashed in half since 1960 and is the lowest ever recorded by the census."
What's more the demographics of wedlock are changing. "As marriage with children becomes an exception rather than the norm, social scientists say it is also becoming the self-selected province of the college-educated and the affluent. The working class and the poor, meanwhile, increasingly steer away from marriage, while living together and bearing children out of wedlock."
