This society is advanced in the sciences and the arts. It has a complex economy and a strong military. It includes many different religions, although religion tends to be a private affair or a matter of civic ceremony.
This particular society also has big problems. Among them is that fertility rates remain below replacement levels. There aren’t enough children being born to replenish the current adult population and to do the work needed to keep society going. The government offers incentives to encourage people to have more babies. But nothing seems to work.
