Brooklyn lies in the USDA 7b plant hardiness zone. Boroughscape Neighborhoods Brooklyn's neighborhoods are dynamic in ethnic composition. For example, the early to mid-20th century, Brownsville had a majority of Jewish residents; since the 1970s it has been majority African American. Midwood during the early 20th century was filled with ethnic Irish, then filled with Jewish residents for nearly 50 years, and is slowly becoming a Pakistani enclave. Brooklyn's most populous racial group, white, declined from 97.2% in 1930 to 46.9% by 1990. The borough attracts people previously living in other cities in the United States. Of these, most come from Chicago, Detroit, San Francisco, Washington, D.C., Baltimore, Philadelphia, Boston, Cincinnati, and Seattle. Community diversity Given New York City's role as a crossroads for immigration from around the world, Brooklyn has evolved a globally cosmopolitan ambiance of its own, demonstrating a robust and growing demographic and cultural diversity with respect to metrics including nationality, religion, race, and domiciliary partnership.

Other notable religious Jewish neighborhoods with a longstanding cultural lineage include Kensington, Canarsie, Sea Gate, and Crown Heights, home to the Chabad world headquarters. Neighborhoods with largely defunct yet historically notable Jewish populations include Flatbush, East Flatbush, Brownsville, East New York, Bensonhurst and Sheepshead Bay (particularly its Madison subsection). Many hospitals in Brooklyn were started by Jewish charities, including Maimonides Medical Center in Borough Park and Brookdale Hospital in East Flatbush. The predominantly Jewish, Crown Heights (and later East Flatbush)-based Madison Democratic Club served as the borough's primary "clubhouse" political venue for decades until the ascendancy of Meade Esposito's rival, Canarsie-based Thomas Jefferson Democratic Club in the 1960s and 1970s, playing an integral role in the
