Sacramento County's 175th Anniversary

​This year marks a significant milestone in the history of Sacramento County as it celebrates its 175th anniversary, also known as its
“Demisemiseptcent​ennial." 

Since its founding in 1850, Sacramento County has been at the forefront of service delivery, continually evolving to meet the needs of its residents with integrity and innovation. Sacramento County was incorporated in 1850 in response  to the needs of a growing population. The County is one of the original 27 counties of California. The County Charter was established in 1933 and is still in use today. 

Sacramento County has grown into a dynamic community. The County's population in 1850 was 9,087,* and now serves more than 1.5 million residents across its diverse landscape. Over the past 175 years, the County has remained committed to providing essential services that enhance the quality of life for all who call it home. 

The County's responsibilities to its residents have grown over the years, pursuant to the County Charter or ordinances, or by state or federal mandate, to provide health and welfare, criminal justice and municipal services (including law enforcement), as well as other services to County residents. Major services include the Airport System, Animal Care and Regulation, Clerk Recorder, Criminal Justice, Health and Welfare, Property Tax System, Regional Parks, Transportation, Waste Management and Recycling, Voter Registration, and Water Resources.​

As we celebrate this milestone, Sacramento County invites residents to reflect on our shared history and look forward to a future filled with continued growth and opportunity. Join us throughout the year as we commemorate 175 years of service, innovation, and community spirit.​
