The inequality in spatial development and socio-economic classes paired with concerns of poverty reduction and climate change are factors in achieving global sustainable cities, as highlighted by the United Nations Sustainable Development Goal 11. According to the UCLG there are differences between regional and national conditions, framework and practice that are overcome in the international commitment to communication and negotiation with other governments, communities and the private sector to continue to develop through innovative and participatory approaches in strategic decisions, building consensus and monitoring performance management and raising investment. Social factors of sustainable cities According to the United Nations Development Programme (UNDP), over half of the world's population is concentrated in cities, a proportion which is expected to rise to two-thirds by 2050.

Gender is a key part of a person's identity, which can influence their experiences and opportunities as they navigate through life. This is no different for how gender impacts how they navigate through the built environment. Men and women experience the built environment differently. For over two decades, professionals in urban planning have called for the routine consideration of gender relations and gendered experiences in the urban design process. Specifically, city planners emphasize the need to account for systemic differences in people's lived experiences by gender, when designing built environments that are safe and equitable. This applies to the development of climate resilient cities. Women represent 80% of people who've been displaced by the climate crisis. Women are more vulnerable to the impacts of climate change because of the roles they are socially assigned by gender. For instance, women are primarily responsible for food
