This paper presents an empirical analysis of the effects of high-density zoning on multifamily housing construction from 1990 to 2000 in the suburbs of six US metropolitan areas. Zoning constraints are measured as the total number of high-density units allowed by right in each suburban jurisdiction obtained from local zoning ordinances and geographical information data.

Sprawl opponents have blamed sprawl for weakening linkages among the residents and social capital but there is a lack of empirical evidence to support their argument. This study examines the relationship between the county sprawl index and social-capital factors from the 2000 Social Capital Community Benchmark Survey data. Using 3-level hierarchical models, this study shows that for the US, urban sprawl may support some types of social capital while negatively impacting the others.

Purpose

The study contributes to the existing debate over the impact of distance to historic preservation sites and landmarks and property prices.
