Words can mean different things to different people.
We keep bandying about the term 'city' with regards to the most suitable radar detector, yet the term is not uniform to all parts of the country or to all lifestyles.
For the sake of defining a Newbies' environment,
I propose that on RD.net a city is defined as
- a Municipality [city limits of a single jurisdiction]
with a minimum population of 750,000
- a Metro area[can include multiple jurisdictions]
with a minimum population of 3,000,000
