In New York State, sheriffs are typically elected rather than appointed. The state constitution requires each county to have a sheriff, making it a constitutional office in the majority of circumstances. However, there are some specific exemptions:

1. New York City: Comprising five counties (the five boroughs), where sheriffs are appointed rather than elected.
2. Charter Counties: Counties that have adopted a charter can potentially have appointed sheriffs, but this is uncommon.

Other exemptions may exist based on specific local laws or regulations, but these are rare and typically involve unique governmental structures.

For further detailed insight, you can refer to County Government Organization in New York State.

If you need specific data on each county, reviewing the reports or reaching out to local government offices might be necessary.
