Population History of Seattle

Pre-1850s: Before European and American settlers arrived, the area now known as Seattle was inhabited by Native American tribes, notably the Duwamish and Suquamish tribes.

1850s: The Denny Party, considered the city’s first permanent European settlers, arrived in 1851. By 1860, Seattle’s population had grown to around 300, driven mainly by the lumber industry.

Late 1800s: The population began to increase more rapidly after the city became the terminus of the Northern Pacific Railway in 1884. By 1890, the population had reached 42,837, and the Klondike Gold Rush of 1897 further accelerated growth.

Early 1900s: By 1910, the population had risen to 237,194. Completing the Lake Washington Ship Canal in 1917 boosted the economy and population.

World War II era: The war years saw another significant population surge, primarily due to the growth of Boeing and the city’s importance in aircraft production. The population hit 467,591 by 1950.

Late 20th Century: The latter half of the century saw steady growth, with the city’s population surpassing 500,000 in the 1960s. The tech boom, driven in part by Microsoft’s founding in 1975, brought a new wave of residents.

Early 21st Century: The tech industry, led by giants like Microsoft and Amazon, continued to spur population growth. By 2010, Seattle’s population was about 608,660. The subsequent decade saw significant growth, with the population exceeding 750,000 by 2020.

Throughout its history, Seattle’s population growth has been influenced by various economic, cultural, and technological factors. From its early days as a lumber and maritime hub to its current status as a global tech powerhouse, the city’s demographics have continuously evolved.
