Beyond Proximity and Towards Equity: A Multidimensional View of Urban Greenspace Access

Park access is primarily conceived of as a question of proximity. We sought to develop a multidimensional tool based on a broad theory of green space access to better understand objective and subjective factors that capture varying dimensions of urban green space access that may be associated with its use.

We conducted a cross-sectional study in two communities bordering a large park in Baltimore City, Maryland. We randomly selected households for an in-person survey conducted between April to September 2019. Our primary outcome was self-reported number of park visits over the last 30 days. The main independent variables conceptualized park access based on Penchansky and Thomas' theory of access.

Based on 87 respondents, living within a 10-minute walk was not associated with park use. Park use was associated with the perception that there were park events that individuals could participate in (adjusted IRR 6.83 [95% CI 2.57, 18.2]) and feeling safe in the park during the day (adjusted IRR 6.26 [95% CI 2.18, 18.0]). Those who reported that living near the park was affordable reported fewer park visits (adjusted IRR 0.53 [95% CI 0.32, 0.86]).

Physical proximity was not significantly associated with green space use, but perceptions of safety, programming, and neighborhood affordability were. Our findings highlight the importance of subjective factors as part of a broader theory of park access.
