This year, the members of Generation Z—born roughly from 1997 to 2010—will begin entering their mid-twenties.

As this first post-Millennial generation reaches adulthood, we stand at the cusp of a once-in-a-generation transformation in parenting and childhood. The public, private and social sectors should all be paying close attention. They need to understand what Gen Z will expect and demand from them — and how to support Gen Z as they take up the full responsibilities of citizenship, employment and parenthood.
