Traditional forms of land use pinkline communities, constrain mobility, limit employment opportunities, reinforce outdated family structures as the norm, and provide inadequate support systems for women (Fainstein & Servon, 2005). Yet, little has been done in practice to address these concerns, and gender issues are still largely marginalized to the periphery of planning (Leavitt, 2003). However, aging-related work in planning has gained momentum in recent years (Warner et al., 2016), and there are similarities between the needs of an aging population and the needs of women around housing, transportation, and services.This dissertation has three goals. Theoretically, this dissertation brings together multiple lines of literature to create a theory of pinklining, the division of space, and exclusion of women and women's needs from mainstream planning. Empirically, this project operationalizes feminist criticisms of traditional zoning regulations, transportation planning, and public participation processes by creating and analyzing the 2014 Women and Aging survey. Practically, this project identifies potential planning interventions that can address the needs of women. This dissertation uses four regression models to test for gender responsive planning in a sample of U.S. communities. Two models evaluate the broad factors contributing to a community engaging in either gender responsive land use or gender responsive transportation planning. Two additional models disaggregate aging from gender to determine which factors are the strongest drivers of gender responsive planning. Data for this dissertation is primarily from the 2014 Women and Aging survey, an online survey conducted in collaboration with the American Planning Association's Planning and Women Division. Results from the regression models reveal that traditional land use regulations are relatively stuck in place and unable to address issues of gender adequately at the time of the survey. The models also demonstrate that there is potential for gender issues to move forward in discussion and resolution with transportation planning. Furthermore, leveraging aging work is an important tool to continue the conversation about gender issues in land use and transportation planning. With planners already advancing the aging population's needs, they should also advocate planning for women to create more equitable, inclusive, and livable communities for all.
