More than 40 percent of the households in seven Western New York neighborhoods contain but a single resident.
The U.S. Census Bureau defines a household as one or more persons who live in a given house, apartment, condominium or trailer, regardless of whether they are related by blood or marriage.
A majority of households, of course, have multiple residents. But seven Western New York ZIP codes — five in Buffalo and two in Niagara Falls — exceed 40 percent in terms of people living alone.
