Here's why:
* General rule: Nouns that describe groups of people (like "community," "people," "population") are not capitalized unless they are part of a proper noun.
* Proper nouns: Proper nouns are names of specific people, places, or things, and are always capitalized (e.g., "South Asia").
* Descriptive term: In "South Asian community," "community" is a descriptive term, not a proper noun. It describes the type of group, not the group itself.
Example:
* Correct: The South Asian community celebrated Diwali.
* Incorrect: The South Asian Community celebrated Diwali.
Exception: If "community" is used as part of a formal organization name, then it would be capitalized. For example, the "South Asian Community Center" would be capitalized.
