Welcome to Seattle Planning Information and Data Resource (SPIDR) Center, a "virtual center" developed to provide a centralized resource for those who want greater access to planning-related information and electronic data. Our goal is to make it easier for you to access maps, data, and information related to city planning in Seattle.

While this site does contain population and demographics information and data, including an interactive mapping tool to explore 1990 and 2000 Census data, information that is more targeted to population and demographics needs is located on the City'sPopulation and Demographics website.

Any comments or suggestions regarding this site should be directed to Jennifer Pettyjohn, GIS Analyst in DPD's Comprehensive Planning Unit, (206) 386-9041, jennifer.pettyjohn@seattle.gov.

We hope you enjoy your visit.

Please note: If you have a request for maps or GIS data, please look around the SPIDR site to see if you can find relevant information to meet your needs. If not, then please review our tip sheet for mapping and data requests before you attempt to contact us. Thank you.
