Santa Rosa, California Population 2018

Santa Rosa is located in the state of California. It is the county seat for Sonoma County.

It is also the largest city by population in Sonoma County, with recent estimates putting the population at 186,170.

Santa Rosa History

What is now Santa Rosa was originally inhabited by the Bitakomtara tribe. This tribe was very protective over the land and imposed harsh punishments for those who tried to enter. When the Europeans arrived, much of the tribe died from smallpox. The population of this tribe had dropped by 95% by the 20th century.

A permanent European settlement was established during the 1830s, and Santa Rosa was founded in 1833. By the mid-1800s, a post and general store were built and several locals began planning out the city. Santa Rosa was incorporated as a city in 1868.

Once California became a state, the population of Santa Rosa grew at a slow and steady pace. Though it didn’t keep up with other cities, it continued on the upward trajectory even when other cities saw a decline in its population.

At the beginning of the 20th century, the San Francisco earthquake destroyed much of the downtown area, but the population did not drop. However, growth slowed even further.

Another earthquake in 1969 led to reconstruction of the downtown area. However, some of these historic buildings still remain including the Empire Building.

After World War II, the city saw more rapid growth because it was the site of Naval Auxiliary Landing Field Santa Rosa. During the 1950s and 1960s, the population increased quite significantly compared to previous years. This was mainly due to immigration and annexation.

The city is divided into four different quadrants: the Southeast, Southwest, Northeast and Northwest. Santa Rosa has continued to grow with the addition of shopping centers, malls, banks, and commercial districts. The city has been named as one of the Best Places For Business and Careers by Forbes magazine, although that rating has dropped because of the reduced job growth, high cost of housing and higher cost of doing business.
