The seven North Shore political districts with elections this November had an average total population increase of more than 5% since 2012 led by the growth of minority populations over the past 10 years, a reflection of local trends from the 2020 U.S. Census.

The maps analyzed by Blank Slate Media were the state’s 3rd and 4th Congressional Districts, the state’s 7th Senate District and the state’s 13th, 15th, 16th and 19th Assembly Districts.

Population data was taken from the U.S. Department of Justice and the 2012 and recently approved 2022 maps from the state’s Legislative Task Force on Demographic Research and Reapportionment.

Demographics listed in the data were White, Black, Hispanic, Asian, American Indian, Hawaiin-Pacific Islander, Multiracial and Other.

Both the 3rd and 4th Congressional Districts had an 8.25% increase in total population over the past decade, growing from more than 717,700 residents to 776,971 in 2022. The White population in both districts decreased by an average of more than 13%, figures showed. 

Fewer than 400,000 White people reside in the 4th Congressional District, which currently includes the communities of Baldwin, Bellmore, East Rockaway, East Meadow, the Five Towns, Lynbrook, Floral Park, Franklin Square, Garden City, Garden City Park, Hempstead, Atlantic Beach, Long Beach, Malverne, Freeport, Merrick, Mineola, Carle Place, New Hyde Park, Oceanside, Rockville Centre, Roosevelt, Uniondale, Wantagh, West Hempstead, Westbury and parts of Valley Stream.

While the 3rd Congressional District under the new map does not extend as far west as the Bronx or Westchester, it does stretch to more southern parts of Nassau County such as Hicksville and Massapequa.

The 15th, 16th and 19th Districts had more than 91,000 White residents in 2012, while none had more than 88,000 in 2022. The 13th District had more than 82,000 White residents in 2012, but decreased to 63,400 in 2022, the lowest total figure out of all seven districts.

More than 28,000 Black residents are in the 3rd District, an increase from the nearly 22,000 residing in it a decade ago.

Black populations increased by 12% or less in the 13th, 16th and 19th Assembly Districts while significantly decreasing in the 7th Senate District and the 15th Assembly District.

The 7th Senate District had nearly 24,000 Black residents in 2012, a number which has decreased to 7,500 10 years later. The 15th Assembly District went from 3,056 Black residents in 2012 to 2,138 in 2022.
