Visualizing Density is a collaboration between CDO+UIC and Alex Ihnen of Next STL, with the help of the Pulitzer Foundation for the Arts, where it was initially shown at their PXSTL pavilion in 2014. Density is an abstract concept to many people, but a critical component of making decisions about what a rapidly changing urban area should become. The exhibit begins with a focus on the past 60 years of population decline in the City of St. Louis across the cities many neighborhoods and draws correlations between other factors, such as household size and land use changes. This information is then used to ask questions about where the city stands in terms of density and what is feasible in the future, while looking to other cities and districts for comparison. The exhibit has since been shown at the St. Louis Planning and Urban Design offices and will be traveling to other venues around the City.
