List of members of the New York United States House delegation, district boundaries, and district political ratings according to the CPVI. The delegation has a total of 27 members, with 21 Democrats and 6 Republicans as of 2018.
Note A: There are now 62 counties in New York (state). The counties that are not mentioned in this list had not yet been established, or sufficiently organized.
Note B: For the 1789 through 1796 elections, districts were named by the counties that comprised them, without applying a numbering system. For those elections, numbers were retroactively back-numbered for the districts.
The geographical area of the congressional districts remained at this election the same as at the previous election in December 1794. A new county was created, Schoharie County Most of the new Schoharie County was taken from Albany County, and remained in the 8th district, a part was taken from Otsego County, and remained in the 10th district. Besides, inside the 10th district a new county had been created: Steuben County.
The districts remained the same as at the previous election in April 1798, but two new counties were created in 1799: in the 7th district, Essex County was split from Clinton County; and in the 10th district, Cayuga County was split from Onondaga County.
Until the previous elections, there had been ten congressional districts. After the U.S. census of 1800, Congress re-apportioned the seats, and New York's representation was increased to 17. On March 30, 1802, the New York State Legislature re-apportioned the congressional districts, dividing New York County seemingly at random into two districts.
After the election of one Democratic-Republican and one Federalist in 1802, the Democratic-Republican majority in the State Legislature gerrymandered the two districts together in an Act passed on March 20, 1804, so that two congressmen would be elected on a general ticket by the voters of both districts, assuring the election of two Democratic-Republicans.
Besides, Seneca County was split from Cayuga County inside the 17th district.
Three new counties had been created since the last elections in 1804: inside the 15th district, Jefferson County was split off from Oneida County; in the 16th district, Madison County from Chenango County; and in the 17th district, Allegany County from Genesee County The area of the districts remained the same.
On April 8, 1808, the State Legislature re-apportioned the districts again, separating the 2nd and the 3rd district, and creating two districts with two seats each to be filled on a general ticket: the 2nd and the 6th.
David Thomas had been elected in the old 12th district which had comprised only Washington County, so the vacancy was filled by a special election held only in this county, while at the same time two representatives were elected on a general ticket in the new 6th district to which Washington County had been re-districted together with Columbia County and Rensselaer County.
Due to the double-seat districts, there were then only 15 districts; the 16th and 17th were eliminated.
Note: There are now 62 counties in the State of New York. The counties which are not mentioned in this list had not yet been established, or sufficiently organized, the area being included in one or more of the above-mentioned counties.
The districts remained the same as at the previous elections in 1808. Only four new counties were created inside some districts: in the 5th district, Sullivan County was split from Ulster County; in the 7th district, Schenectady County was split from Albany County; in the 8th district, Franklin County was split from Clinton County; and in the 15th district, Niagara County was split from Genesee County.
Due to the increase in seats, the previously eliminated 16th and 17th district were re-established, and four more districts were created. Six districts had two members, elected districtwide on a general ticket.
For the 1818 elections, the geographical area of the districts remained the same as at the previous elections in 1816. Two new counties were created: Tompkins inside the 20th district; and Cattaraugus inside the 21st district. In 1817, the Town of Danube was separated from the Town of Minden in Montgomery County, and transferred to Herkimer County, but Danube remained in the 14th district.
For the 1821 elections, except for the split of the 21st district, the geographical area of the congressional districts remained the same as at the previous elections in 1818. Five new counties had been created. Hamilton County was split from Montgomery County inside the 14th district. Oswego County was created from parts of Oneida and Onondaga counties, but the parts remained in their previous congressional districts. On March 9, 1821, the New York State Legislature divided the 21st district in two districts: Ontario County and the newly created Monroe County remained as the 21st district; the remainder became the new 22nd district, including the new counties of Erie and Livingston.
On April 17, 1822, the New York State Legislature re-apportioned the congressional districts according to the figures of the 1820 United States census. The number of district was increased to 30, creating eight new districts; the number of seats was increased to 34, creating for the first time a triple-seat district, and keeping two double-seat districts.
The geographical area of the congressional districts remained the same as at the previous elections in 1824. Only one new county was created: in the 29th district, Orleans County was split from Genesee County.
^The numbers which are used nowadays to describe these districts at this time derive from the numbers of the districts officially introduced in 1797, considering the sequence of the districts in the official listing and the approximate geographical equivalence.
^ abIn the Act of March 23, 1797, the Towns of Clarkstown, Haverstraw, Hempsted and Orangetown are mentioned. These towns were split from Orange County in 1798, before the election, to form Rockland County.
