Your chart shows just that there are more single mothers. What the chart fails to indicate is that 40% of babies are born to unmarried couples these days, many of whom are a happy couple but just not married.

There has always been families of all sorts - single moms, blended families, happy and unhappy marriages, etc. (source: wife who is a sociology professor).
