Intra metropolitan demographic structure: a Seattle example
Abstract:
"Internal urban variation in demographic character (births, deaths, fertility, natural increase, net migration) is analyzed in relation to age of persons, age of housing, ownership, distance from the CBD [central business district], race, household type and size. A descriptive analysis of maps of these characteristics is followed by simple statistical tests of relations among the variables, in particular distance from the city center. Predictable and strong patterns of spatial structure are consonant with expectations from economic, social, geographic and political urban theory." Data concern King County, Washington, for the period 1980-1985, (the city of Seattle) and are from local sources, including the Puget Sound Council of Governments.
