City's Jewish American community at its late 1940s social apogee) from the historically affluent, Old Stock and Jewish American-dominated tracts east of Coney Island Avenue. In his 2015 memoir, musician Marky Ramone (who resided at 640 Ditmas Avenue throughout much of his childhood in the 1960s) noted the area's distance from major thoroughfares in eastern Flatbush, necessitating a two-fare zone via bus to Erasmus Hall High School. As demographic shifts in the eastern tracts — exemplified by white flight among the Jewish American community and the concomitant emergence of an Afro-Caribbean community in the vicinity of Flatbush Avenue, in contrast to demographic stability in the Kensington tracts amid the 1956 closure and ensuing "bustitution" of the Church Avenue streetcar line — accelerated throughout the 1960s, The New York Times would characterize Ocean Parkway as the western boundary of Flatbush by early 1968. Shortly thereafter, the New York City municipal government informally designated the tracts between McDonald and Coney Island Avenues as Kensington in the 1969 Plan for New York City. Similarly, Gilbert Tauber and Samuel Kaplan asserted that southern Windsor Terrace, the traditional Kensington tracts and western Midwood constituted the sprawling neighborhood of "Kensington-Ocean Parkway" in The New York City Handbook, first published by Doubleday in 1966. (Indeed, after the contemporary community boards of New York City were established in 1963, much of present-day Kensington was appended to the Borough Park-dominated Brooklyn Community Board 12, possibly stemming from Kensington Democratic leader Howard Golden's affiliation with Borough Park's then-powerful Roosevelt Club. Conversely, the eastern Flatbush and Midwood tracts were incorporated into Brooklyn Community Board 14, a division that endures to the present.) Although the formation of such community organizations as the Kensington/Flatbush Preservation Association would further popularize the moniker throughout the 1970s, press accounts continued to describe the area as Flatbush. During this period, the Kensington tracts began to experience significant demographic changes. Most of the area's Protestant churches were forced to close due to a lack of parishioners, while the area's longstanding Irish American community was largely supplanted by a new wave of upwardly mobile Italian Americans moving out from less desirable sections of South Brooklyn, paralleling developments in nearby Sunset Park. In a 1974 interview with Wendy Schuman of The New York Times, a banker opined that Ocean Parkway "just [wasn't] prestigious anymore" as younger residents gradually embraced postwar suburbanization, leaving a substantial and rapidly aging white ethnic population
