Homogeneity versus heterogeneity in household structure: the recent experience of twenty US cities

"This paper is an investigation of the variation in household structure at the census tract level in twenty US cities between 1970 and 1980. Results indicate that households were, in 1980, more likely to reside in proximity to households with different compositions. In 1980 the most genuinely diverse census tracts, in terms of household composition, were in neighborhoods with recently constructed, single-family housing."
