According to the 2009 American Community Survey, White Americans made up 54.6% of Brooklyn's population. Black Americans made up 34.2% of Brooklyn's population; non-Hispanic black people made up 32.9% of the population. Native Americans made up 0.3% of Brooklyn's population. Asian Americans made up 9.5% of the population; Pacific Islander Americans made up 0.1% of the populace. Multiracial Americans made up 1.4% of Brooklyn's population. Hispanic and Latino Americans made up 19.6% of Brooklyn's population.

European Americans

According to the 2009 American Community Survey, white Americans made up a majority (54.6%) of Brooklyn's population, of which 51.9% are non-Hispanic whites. Whites (both Hispanic and non-Hispanic) number near 1.3 million individuals, and there are nearly 1.15 million non-Hispanic whites residing in Brooklyn.

As of the 2020s, the European White American communities are mainly concentrated in southern parts of Brooklyn and northwestern sections of Brooklyn. The Italian Americans are mainly concentrated in Dyker Heights, Bensonhurst, Bath Beach, Mill Basin and Gravesend and in scattered parts of northwest Brooklyn such as Williamsburg, Carroll Gardens, and Cobble Hill; however, Bensonhurst has long held the name as the Little Italy of Brooklyn despite its ongoing slow decline since the 2000s as more of them are migrating to the suburbs with the Asian population increasing in Bensonhurst. Jewish Americans are mainly concentrated in Borough Park, Sheepshead Bay, Midwood, Kensington, Gravesend, Brighton Beach, and Coney Island. There is a significant Polish Community in Greenpoint often with the nickname, "Little Poland" though due to gentrification it is experiencing significant decline. The Russian-speaking communities are mainly concentrated in Brighton Beach and Sheepshead Bay though with some of them overlapping into Bensonhurst as well.

Lapskaus Boulevard in Bay Ridge and Sunset Park has long been a Norwegian enclave and the neighborhoods have also been home to many Swedish and Danish immigrants while the northern part of Sunset Park is also home to a sizable Finnish immigrant enclave called Finntown, surrounding the park of the same name, bounded by 5th Avenue to the west and 8th Avenue to the east, 39th Street to the north and 45th Street to the south. The Finns brought with them the concept of cooperative housing, and the Alku and Alku Toinen apartment house at 816 43rd Street is said to be the first cooperative apartment building in New York City. However, by the mid 20th century, these neighborhoods were increasingly being shared with Latino and Asian residents, though significant numbers of the Nordic Americans still remain, but in lower numbers than their peak periods in the early to mid 20th century.

Historically during the early-to-mid-20th century, areas surrounding Bedford Stuyvesant such as Crown Heights, Ocean Hill, Brownsville, East New York, Bushwick, Flatbush, East Flatbush, and Canarsie were once mainly populated by European Americans with many being Italian and Jewish enclaves though with some Irish and German enclaves. Even Bedford Stuyvesant also had a significant Jewish and Italian presence until the 1940s. However, within the mid-to-late 20th century, they all slowly began to shift into majority African-American/West Indian American neighborhoods with some limited Latino enclaves in Bushwick, Cypress Hills, and a portion of East New York. During the 1950s–'90s, these neighborhoods experienced en masse White flight.

A section of Crown Heights and a section of Flatbush still have significant remaining small Jewish enclaves. A subsection neighborhood of East New York called Starrett City or Spring Creek still have significant scattered numbers of European Americans. However, in recent decades since the 2000s and especially since the 2010s, the White population has started to rapidly regrow in Bedford Stuyvesant, Crown Heights, Bushwick, Ocean Hill, and Flatbush, which these areas are undergoing gentrification. Since the early 2020s, even Brownsville is also experiencing a resurgence of a growing Jewish community as a result of young orthodox Jewish families coming from Crown Heights to seek affordable homes to purchase as property values and sales prices of homes in Crown Heights have largely spiked and gentrified immensely.

According to the 2009 American Community Survey, the six most common European ancestries were the following.

As according to the 2020 census data, the White European American population in Brooklyn increased from 893,306 residents at 35.7% in 2010 to 968,427 residents at 35.4% in 2020 a gain of 75,121 residents or 8.4%, though the percentage portion of White residents out of the total population of Brooklyn slightly declined due to other racial populations increasing adding to the population.

African Americans According to the 2009 American Community Survey, African Americans made up over one-third (34.2%) of Brooklyn's population. There are over 877,000 African Americans residing in Brooklyn. The historical cultural center of the borough has long been Bedford–Stuyvesant; African Americans became a majority in Bedford–Stuyvesant in the 1930s following the construction of the A line subway between Harlem and Bedford. Bedford-Stuyvesant was the first large African-American community to be established in Brooklyn back then.

After Bedford–Stuyvesant had largely developed into an African-American community in the 1930s–'40s, neighborhoods surrounding Bedford–Stuyvesant in Northern and Eastern Brooklyn such as Ocean Hill, Brownsville, Crown Heights, Flatbush, Kensington, Canarsie, East Flatbush, Prospect Lefferts Gardens, East New York and Fort Greene had continued to be mostly home to Italian and Jewish enclaves with some Germans and Irish intermixed in even though some of the growing African-American population also did spillover into some of these neighborhoods. However, through the processes of a Ripple effect, a Domino effect, and a Snowball effect, starting in the 1950s and throughout the remainder of the 20th century, these surrounding neighborhoods became the next areas to slowly transition to majority African-American communities. Large West Indian Black communities have also emerged and intertwined in some of these areas. As a result, a very large portion of the northern half of Brooklyn is dominantly populated by African Americans with significant West Indian Black enclaves, though Crown Heights and Flatbush continue to have remaining small significant Jewish communities. The roads of Eastern Parkway, Malcolm X Boulevard, Kings Highway, Broadway, Atlantic Avenue, Linden Boulevard, Flatlands Avenue and Jackie Robinson Parkway connect all of these neighborhoods to the point of being very comparatively similar to the city of Newark in terms of the geographic size and the dominantly Black communities.
