In my yet to be named sci-fi universe humanity has begun to expand into space and has established large scale space stations near Earth and on places like Eros and Luna. I wanted the stereotypical "spacer" to have more children than is usual on earth (1 or 2). Are there any logical reasons or advantages for spacers to have multiple children in a space colony?
- The Hegemony (global government which controls the majority of humanity) practices birth credits (after a couple's second child they would need to buy permits for any further child) to try and prevent drastic population growth, but in my mind I don't think simply wanting to have more than 3 kids without buying a permit is a good enough reason or motivator to move to space.
- Space stations are required to be built with "Maternity Centers" which allow pregnancy, birth, and development to be done in near earth gravity.
- Most space colonies are built around mining and/or energy generation, manufacturing, and trade with other colonies (and for certain resources that are worth the cost) and Earth. As well as science experiments and tests on the side
