What is correct and why?

Question

1. New York citizens must recycle plastic bottles.

2. New York's citizens must recycle plastic bottles.

Answer 1

The second one seems the most correct.

Since the citizens belong to New York...

Hope it answers your question

Answer 2

They're both correct.  

Answer 3

1 cuz i said so well idk im just guessing

Answer 4

Both are correct grammatically, and the meanings of both are identical.   It's just a matter of choice, which one to use, but I prefer the first one which is more formal when writing for a general public newspaper. However, if you're addressing a less formal audience, such as in a bulletin or newsletter, the second one would be fine also.    

Answer 5

The second one is technically correct when possessive nouns are used. One would not say or write :

America/Britain youths..., London traffic is...John room is....involving names/proper nouns,  which sound incomplete and awkward  without  the use of  's.

Answer 6

Both are grammatically correct. You can choose either..
