Households’ preferences, constraints, and resources shape residential segregation patterns. These factors vary according to their demographic features, including the composition of the household. Drawing on US Census and American Community Survey data, I estimate segregation of households with and without children between neighborhoods, places (municipalities), and cities and suburbs in the 100 most populous metropolitan areas in the US from 1990 to 2014. Households with and without children became less segregated and the city–suburban divide in their location weakened over time. I then examine income segregation among households with and without children among these same three geographies. Income segregation is higher and increased more among households with children, and high- and low-income parents are increasingly separating across places. However, high- and low-income households with children are segregating more between suburbs, not between cities and suburbs. Together, these analyses reveal how household demography shapes residential sorting within and between places.
