This study delves into the intricate relationship between the elderly population and public transportation accessibility, particularly focusing on the Brooklyn borough within New York City. The aim is to dissect the challenges faced by seniors in utilizing public transit systems, with a specific emphasis on subway accessibility. Using Neighborhood Tabulation Areas (NTA) data as the primary unit of analysis, the research examines a spectrum of socio-economic variables and infrastructural elements to unravel the complexities underlying elderly mobility. Key variables include population density, median household income, demographics, poverty rates, and reliance of seniors on public transit. Moreover, the study maps out the distribution of facilities such as subway stations, bus stops, senior centers, and parks across Brooklyn’s neighborhoods. By amalgamating spatial data from diverse sources including the U.S. Census, NYC DCP, MTA, and non-spatial data from the American Community Survey (ACS), this research strives to illuminate spatial patterns, identify areas with the highest concentration of senior populations, assess the presence of accessible transit stations along with bus route coverage, and propose optimal locations for new accessible subway stations. Ultimately, this endeavor seeks to provide actionable insights aimed at enhancing transportation equity and accessibility for the elderly population in Brooklyn.
