Census 2010: Average Household Sizes in Seattle

In previous posts I have mapped the population density and household density of the City of Seattle.  The difference between the two maps is household size.  So I also created a map of average household size in the City of Seattle, based on the U.S. Census 2010 data, which I have guest-posted on the  Seattle’s Land Use [...]

Portlandia’s low population density

It’s been a bit quiet over here at Build the City lately. I ran into trouble with an open-source GIS program, then got busy at work, and then took a two-week vacation to Europe. I will write some observations about the cities I visited in Europe (eventually), but today I saw an article in the Oregonian [...]

Census 2010: City of Seattle household density map

I have created another map of Seattle’s population density, using units of gross households/acre.  This a measure of the built environment rather than of population, since household sizes can vary with time and between neighborhoods (maybe I’ll make a map of that also).  Net housing units/acre is a commonly used measure in land use planning and [...]

Next up in my series on the Census 2010 results is a population density map for the Seattle-Tacoma metropolitan area.  The GMA urban growth area (UGA) boundaries are shown for King and Snohomish counties (I’d love to also show the Pierce County growth boundaries, but alas, their data sharing policy is c. 1998). A few points [...]

Seattle, not Snoqualmie, is the state’s fastest growing city

How methods shift perception of population growth The Seattle Times recently reported on 2010 census data by tabulating the “fastest growing” cities in Washington State and writing a feature about Snoqualmie, on the top of the list at 396% growth since 2000. As with many media outlets, they ranked areas based on percentage growth, not absolute numbers of people.  In [...]

2010 Census data: Seattle’s urban village strategy is succeeding

The Seattle neighborhoods defined as urban centers and urban villages received most of the City’s population growth during the past 10 years.  The U.S. Census Bureau recently released initial 2010 census data for Washington state.   I will have a series of posts about the new census data, and in this first post I look at Seattle’s neighborhoods.  I [...]
