I believe the answer is: <span>education levels among women increase.
Studies show that as educations levels among women increase, the awareness of the hardship that they might encountered when they're having too many children (or too early) started to increase. This could lead to small number of newborns and lead to zero population growth.</span>
So a social group is a group of people that share similar characteristics. And they are important because it gets you to interact with peers. The last question is one you have to answer on your own so I play baseball and I am a Highschooler so therefore two Social Groups for me would be Baseball, and Highschool
I hope this helps :)
