The disambiguation was performed after this answer to another question.
- We do not yet have A real solution to ambiguous tags If I were to choose new-york I would love to be asked "Do you mean new-york-city or new-york-state?" but that functionality has not been implemented.
- Burninating and then blacklisting new-york so that it cannot be used requires a multi-step process which seems like overkill for its level of inconvenience: How should we make tag blacklist requests?
- If we do not blacklist the new-york tag after deleting all occurrences then it will keep coming back each time someone types it in again.
- I think making new-york be a synonym to new-york-city OR new-york-state works well, and to a non-US user like me when we say "New York" we mean the "Big Apple" and are barely aware that there is a state of the same name which is why I chose the "city" over the "state" as the "default".
The plain tag new-york should redirect to new-york-state not new-york-city. If someone is asking a question about a locality in New York State, the answers about how to do research in New York State will hold true for all counties except the five boroughs of New York, and sometimes three other upstate counties. Most of the time someone who wants to tag a question new-york they will be asking about New York State.
However, I still assert that New York City needs its own tag because of the unique circumstances in finding New York City records. Answers for New York State in the modern period will not apply to the five boroughs of New York City after the consolidation.
