How people associate and engage in politics in the 21st century is notably different from similar behaviors in the 20th century. Ryan Salzman examines the political potential of placemaking, an increasingly popular set of behaviors that were unfamiliar to the American public until the last two decades. Placemaking exemplifies a shift that is occurring in the way Americans participate in their political system, and it appears that that participation is increasingly effective in the context of American democracy. Informed by interviews, surveys, and material review, Salzman compares the process of placemaking to traditional political and associational behaviors, providing evidence that placemaking has tremendous political potential. Placemaking is an innovative set of behaviors, largely understood to influence economic and community development. From painting crosswalks to community gardens, Americans are engaging in their communities with real political and civic consequences. This text expands our understanding of placemaking, updating the way we think about civic and political engagement in the 21st century. Pop-Up Civics in 21st Century America: Understanding the Political Potential of Placemaking will be of interest to those who study and research political behavior, civil society, arts and politics, social movements, and urban public policy.
