San Mateo County

San Mateo County was formed in April 1856 out of the southern portion of then-San Francisco County with a population of fewer than 5,000 people and little in the way of commerce. Today, more than 764,000 people call San Mateo County home and it stretches the boundary of Silicon Valley northward. Innovation thrives here in industries including bioscience, computer software, green technology, hospitality, financial management, health care, education and transportation. The County prides itself on how that prosperity fosters its commitment to protecting and enhancing the health, safety, welfare and natural resources of the community.
