Proximity to neighborhood public open space across different socio-economic status areas in metropolitan Tehran

This study examines the proximity to neighborhood public open spaces (NPOS) across different socio-economic areas in metropolitan Tehran. Three proximity variables included access to, number of, and total area of NPOS, which were measured using geographic information systems in a large geographical area. Area-level socio-economic status (SES) was measured by considering income, education, and employment at the scale of census zones and categorized into quintiles. The results show that there are significant differences (without clear pattern) in access to and number of NPOS among SES quintiles in Tehran; however, there was no significant difference in total areas of NPOS across SES quintiles.
