A bit of research for your Sunday

Coming in from Quartz at Work is this bit of research:

After paternity leave was instituted, surveys of Spanish men ages 21 to 40 showed they desired fewer children than before. Farré and González think that spending more time with their children—or the prospect of having to do so—may have made men more acutely aware of the effort and costs associated with childrearing, and, as the researchers put it, “shifted their preferences from child quantity to quality.”

Happy Mother's Day!
