Every 10 years, states redraw the boundaries of their congressional districts to reflect new population counts from the census. New York Judge Patrick McAllister approved the new congressional map drawn by a court-appointed special master. The map most likely gives Democrats an advantage in 19 districts. Under a blocked map the Democratic-controlled legislature drew earlier this year, Democrats had hoped to gain a path to about 22 seats.
New York will have a member vs. member House primary as longtime Manhattan-based Reps. Jerry Nadler and Carolyn Maloney were placed in the new 12th Congressional District.

How the new map shifts voting power by demographic
New York loses one of its 27 seats in the House after the 2020 census. Under the new map, there is an additional Hispanic-majority district in New York City, for a total of three. There are also two fewer White-majority districts.

Methodology note: Vote margins for new congressional districts are determined by calculating precinct-level vote totals for each district. If a new district splits a precinct, block-level voting-age population is used to allocate that precinct’s votes to the new districts. Block-level demographic data from the 2020 census is reaggregated into each new district’s boundaries.
