One common example is that religious cultures have a family culture that can propagates through time by having replacement levels of offspring.

So far, to date, every secular and atheistic culture tends towards inverting the demographic pyramid by having about half the required number of offspring to stabilize their culture/viewpoint through time.

This view assumes that there is any meaning to life, of course.
