0/ I've recently been chatting with people about what it would take to start a new city. It's such an interesting idea to think about! Just like with products, I feel like a startup/charter city should be 10x better for target inhabitants. A few ideas for such cities:

1/ A city for parents -- less nightlife and fewer activities for single people; more options for school, daycare, and enrichment activities; lots of nearby lodging for long in-law visits.

2/ A city for young people just out of school -- lots of fun activities; fewer services for people with families; small, affordable homes.

3/ A city catering to a specific profession. What might a city look like if you designed it for artists or engineers or another specific industry?

4/ A hypoallergenic city for people with severe asthma, compromised immune systems, or allergies -- no allergens in food supply; gas vehicles forbidden; no pets allowed.

5/ A city for night owls -- standard work and school hours are a few hours later; everything is open late; loud noise in the mornings is forbidden.

6/ The cities wouldn't by definition not be for everyone**, but they'd be 10x better alternatives for the groups of people they target.

** If I could, I'd move to a night owl city tomorrow. =P

7/ A few misc thoughts a/b new cities:
- it's cheaper/faster to build next to existing infrastructure, so focus on the outskirts of populated areas.
- it's likely easier to start in low tax areas. Ask new residents coming from high tax places to invest savings into the new city.

8/ If you have thoughts or ideas about new city creation, I'd love to hear them!
