At a guess, your dream place to live and your dream job are in different places. The balancing act is to find a nice compromise, which usually means figuring out a reasonable commute. The Center for Neighborhood Technology analyzed 362 regions for the jobs and transit options available, and compiled the results into a score for each region.
Within the Puget Sound region, Seattle comes out best in every category: the number of transit routes within a half mile (23), jobs accessible within a thirty minute trip (424,924), percentage of commuters using transit (20.98%), and overall score (8.6).
