Dedensification

Dedensification refers to the process of reducing the density of something. In urban planning and geography, it specifically describes a trend where urban populations and building density decrease, often in central city areas, leading to a more dispersed settlement pattern. This can occur as a result of various factors, including suburbanization, deindustrialization, and changes in housing preferences. Cities undergoing dedensification may see vacant or underutilized buildings, a decline in the local tax base, and challenges in maintaining public services.

The phenomenon is distinct from simple population decline, as it often involves a spatial redistribution of people and activities. While the total population might remain stable or even grow in a metropolitan region, the core urban areas experience a reduction in population and built form. This can lead to a spatial mismatch between where people live and where jobs are located, contributing to increased commuting distances and traffic congestion. Addressing dedensification often involves strategies aimed at revitalizing urban cores, encouraging in-fill development, and improving public transportation to make denser living more attractive. It is a complex process with significant social, economic, and environmental implications.
