I was thinking about something: The size of Star-fleet
Since it would be unrealistic to expect significant populations devoting all their efforts to expanding outwards for more than a generation or two -- I'm thinking many federation worlds would be sparse.
- In TOS it was stated that we occupied 1,000 worlds
- In TNG it was stated we occupied 100 worlds
- Our planet has approximately a population of 7 billion
- People are born all the time, and more people are born than die as a general rule in a society which thrives
- A generation is about 25 years as a general rule and adulthood is reached at 21
- It takes time to travel from Star System to Star System even if you have Warp Drive
- It requires a lot of people (about 40,000 according to a NASA estimate) to terraform a planet and it would probably take decades
- Some people do not wish to explore or travel and prefer to stay at home: Some even find jobs which allow them to live close to where they grew up
- Some also contribute little to society: I'm not expressing animosity here, merely pointing out that some people are starving artists, people who bounce from career to career, are lifelong students, are (even in modern day) housewives and a few house husbands; some have no employment
