SUFFOLK COUNTY, NY– Continuing a decade-long trend, Suffolk saw a sharp population decline in 2019, according to new census data published by the United States Census Office. Suffolk lost 4,229 residents between 2018 and 2019 and Nassau saw a reduction of 610 residents.
Suffolk 2019 population was 1,476,601. New York City has also seen population loss, along with many counties in the northeast and New York state, while metropolitan areas in the southwest such as Dallas, Houston and Austin have seen the largest increase in metropolitan areas at the level national. The metropolitan area of New York / Newark / Jersey City is still the most populous in the country with over 19 million inhabitants.
Both Long Island counties have been ranked among those with the largest demographic decline since 2010 in the country, considered counties that have seen a reduction of at least 2,501 residents.
“An interesting trend we’ve seen over the past decade is the widespread population decline among smaller counties, while larger counties tended to have population growth,” said Dr. Christine Hartley, demographer of the Population Division of the census office. “Three out of four counties with a population of less than 10,000 in 2010 had even smaller populations in 2019. At the same time, three out of four counties of 50,000 or more were larger in 2019 than in 2010.” This pattern among the larger counties was particularly evident in the West and South.
The 2020 census has already started.
