Social work practice is best understood and practiced when taking into account the local context. The urban context of social work practice may share much with suburban and rural contexts but also brings with it unique problems and opportunities. Location in urban cities plays a major role on the social, economic, and environmental justice of group populations. Within close proximity and density of some locations, groups of people become isolated due to social and economic status. Subsequently, opportunities that foster well-being are limited and environmental hazards such as water and air pollution further suppress vulnerable group populations, limiting opportunities due to structural disparities. Distribution of environments, resources, and opportunities is connected to social justice through the relationship of people and environment, combined by race, gender, and class. Furthermore, gentrification is an evolving social problem that leads to displacement of vulnerable groups, challenging social workers to be social, economic, environmental, and political change agents that disrupt injustices on behalf of marginalized populations.
