§ 4120. Vital statistics; registration districts; establishment. 1.
Except as otherwise provided in this article, each city, incorporated
village and town in the state shall constitute a separate primary
registration district, except that the commissioner may designate any
county, except those comprising the city of New York, as a primary
registration district with the approval of the board of supervisors of
such county.

2. To facilitate registration, the commissioner may:

(a) with the approval of the legislative body of the county in which
each affected district is located, combine two or more primary
registration districts into a single primary registration district; or,

(b) divide one primary registration district into two or more primary
registration districts; or,

(c) establish any state hospital, charitable or penal institution as a
primary registration district.

3. Whenever a county or part-county primary registration district has
been established or two or more primary registration districts have been
combined, the records of birth and death and all papers pertaining to
such records in the possession of the original primary registration
district or districts shall be transferred as directed by the
commissioner.
