Did you know that the one-child policy has been in effect for almost three decades? With the 30th anniversary approaching, Marketplace has an amazingly comprehensive feature on the vast social changes erected by this sweeping regulation – how it affected parents, the children themselves and all of society. They even have a quiz (test all you know about the one child policy!) and this handy infographic above (made even more handy by little info pop ups when you click on certain years). Worth a look, definitely.
