Current King County Urban Growth Area Boundaries. The Comprehensive Plan designates an UGA which includes areas and densities sufficient to permit the urban growth that is projected to occur in the County for the succeeding 20-year period. Layer is created in reference to King County ordinances that established and amended the Urban Growth Areas. The main point of refference is the cadastral layer maintained by King County Department of the Assessor.

About this dataset

Context

The dataset tabulates the King County population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of King County across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of King County was 2.27 million, a 0.27% increase year-by-year from 2022. Previously, in 2022, King County population was 2.27 million, an increase of 0.55% compared to a population of 2.25 million in 2021. Over the last 20 plus years, between 2000 and 2023, population of King County increased by 531,957. In this period, the peak population was 2.27 million in the year 2020. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.

In 2023, the GDP of the Seatle-Tacoma-Bellevue metro area amounted to 487.77 billion U.S. dollars, an increase from the previous year. The GDP of the United States since 1990 can be accessed here. Seattle metro area The Seattle metropolitan area in the U.S. state of Washington includes the city of Seattle, King County, Snohomish County, and Pierce County within the Puget Sound region. About 4.03 million people were living in the Seattle metro area, which is more than half of Washington's total population in 2021 (about 7.79 million people). This makes the Seattle metro area the 15th largest metropolitan area in the United States, by population. However, Seattle is in fourth place among the 20 largest metro areas in terms of household income, which stood at 94,027 U.S. dollars in 2019. This is by far more than the average household income in the United States. Household income in Washington is on a similar high level. In 2021, the federal state of Washington was ranked 11th in terms of household income among the states of the U.S. The city of Seattle is the largest city in the Pacific Northwest region of North America. It has about 733,820 residents and is among the 25 largest cities in the United States. Seattle has always been an important coastal seaport city and a gateway to Alaska. The importance of the city and metro area is also due to fact that some of the biggest companies worldwide started in Seattle during the 1980s. Companies like Amazon and Microsoft are still based in the Seattle area in the state of Washington.

Preliminary report on the geology of southern Snohomish County, Open File Report 73-1. The map area includes eighty-five square miles in South Snohomish County southeast of Everett, bounded on the west by Interstate 5, on the south by Highway 405 and the Snohomish-King County boundary, on the east and north by the Snohomish River floodplain. The purpose of the project is to provide a geologic map of the area at a scale which can be useful as a tool in urban planning. Since the project has been done in conjunction with the Snohomish County Planning Commission, hopefully, it will provide geologic data that will be useful to them in planning for future metropolitan and industrial growth. The geologic map will provide a basis for applying groundwater, seismic response, slope stability and engineering property studies to the area, all of which are important factors in today's urban and regional planning.
