Brooklyn's population in the 2010 federal census was counted as 2,504,700 people--1.6% higher than in the 2000 census. If our borough were still a city, it would still be the 4th largest city in America.
(Sebastian Leone, Brooklyn Borough President, 1970 to 1976)
Nonetheless, city officials are certain that portions of the borough were undercounted. Brooklyn Borough President Marty Markowitz, for instance, says there must have been an undercounting of Asians in South Brooklyn and residents of Central Brooklyn. A report by Furman Center for Real Estate and Urban Policy cited Brooklyn's population as 2,556,598 in 2008. Mayor Bloomberg is going to officially challenge the census results through a formal appeals process.
New York state's population increased by 2.1% from the 2000 census to the 2010 census. But Mapping the 2010 U.S. Census shows that the population of many states increased by more than 2.1%--sometimes by much more, like Nevada, whose population rose by 35.1%--so New York is going to lose two seats in the House of Representatives and the electoral college.
