Recently, KALW’s Jon Atkinson headed out to Dolores Park to ask the resident young adults there about marriage. He mostly heard the words “outdated,” and “unnecessary” (save for the words of one hopeful park-goer). And those who follow marriage trends wouldn’t be surprised. People like local author Ethan Watters says young people are consciously prolonging the time between graduating from college and starting a family. In the meantime, they form networks of support that sustain them: groups of friends, neighbors, acquaintances, co-workers, and classmates who form a kind of family.
