Should we worry about Millennials not having babies ?

 How old are the millennials? Demographers and researchers typically use the early 1980s as starting birth years and the mid-1990s to early 2000s as ending birth years

Millennials do things “later”
A Pew Research Center report found that millennials “are more than three times as likely to have never married” as their counterparts in the Silent generation, although 65% of never-married millennials reported that they would like to be married one day.

Hi everyone
In this generation one in three women is still single at the age of 35. What about marriage? There is now a divorce rate of one in two, modern women change relationships like we change careers and marriage is no longer the be-all-and-end-all.
Is it a good thing ?
