San Luis Obispo County (
i/sæn ˌluːɪs oʊˈbɪspoʊ/), officially the County of San Luis Obispo, is a county on the Central Coast of California. As of the 2020 census, the population was 282,424. The county seat is San Luis Obispo.
Junípero Serra founded the Mission San Luis Obispo de Tolosa in 1772, and San Luis Obispo grew around it. The small size of the county's communities, scattered along the beaches, coastal hills, and mountains of the Santa Lucia range, provides a wide variety of coastal and inland hill ecologies to support fishing, agriculture, and tourist activities.
California Polytechnic State University has almost 20,000 students. Tourism, especially for the wineries, is popular. Grapes and other agriculture products are an important part of the economy. San Luis Obispo County is the third largest producer of wine in California, surpassed only by Sonoma and Napa counties. Strawberries are the largest agricultural crop in the county.
The town of San Simeon is located at the foot of the ridge where newspaper publisher William Randolph Hearst built Hearst Castle. Other coastal towns (listed from north to south) include Cambria, Cayucos, Morro Bay, and Los Osos -Baywood Park. These cities and villages are located northwest of the city of San Luis Obispo. To the south are Avila Beach and the Five Cities region. The Five Cities originally were: Arroyo Grande, Grover Beach (then known as Grover City), Oceano, Fair Oaks and Halcyon. Today, the Five Cities region consists of Pismo Beach, Grover Beach, Arroyo Grande, Oceano, and Halcyon (basically the area from Pismo Beach to Oceano). Just south of the Five Cities, San Luis Obispo County borders northern Santa Barbara County. Inland, the cities of Paso Robles, Templeton, and Atascadero lie along the Salinas River, near the Paso Robles wine region. San Luis Obispo lies south of Atascadero and north of the Five Cities region.
History
The prehistory of San Luis Obispo County is strongly influenced by the Chumash people. There has been significant settlement here at least as early as the Millingstone Horizon thousands of years ago. Important settlements existed in coastal areas such as Morro Bay and Los Osos.
Mission San Luis Obispo de Tolosa was founded on September 1, 1772, in the area that is now the city of San Luis Obispo. The namesake of the mission, city and county is Saint Louis of Toulouse, the young bishop of Toulouse (Obispo and Tolosa in Spanish) in 1297.
San Luis Obispo County was one of the original counties of California, created in 1850 at the time of statehood.
The Salinas River Valley, a region that figures strongly in several John Steinbeck novels, stretches north from San Luis Obispo County.
Geography
According to the U.S. Census Bureau, the county has a total area of 3,616 square miles (9,370 km2), of which 3,299 square miles (8,540 km2) is land and 317 square miles (820 km2) (comprising 8.8%) is water.
Climate
San Luis Obispo County has three main climate types. BSk climate can mainly be found in the eastern portions of the county, along with certain smaller areas in the north. Csa climate can mainly be found in the central portions of the counties, in communities such as Paso Robles. The rest of the county is made up of the Csb climate type. The Csb warm-summer mediterranean type climate together with the county's varied landscapes reminds visitors of European locales.

Economy
.jpg)
The mainstays of the economy are California Polytechnic State University with its almost 20,000 students, tourism, and agriculture. The economic indicators reveal that San Luis Obispo County aligns closely with California regarding median household income and poverty rates. However, the county distinguishes itself through higher educational attainment and homeownership rates, alongside a distinctive employment sector composition favoring agriculture and related industries. Despite these strengths, the county is not immune to challenges, as evidenced by a housing market that is significantly more expensive than the rest of California and growing income inequality. San Luis Obispo County's economy is primarily a service economy. Service jobs account for 38% of the county's jobs, government jobs accounts for 20.7%, and manufacturing jobs represent 6% of the county's jobs.
San Luis Obispo County is the third largest producer of wine in California, surpassed only by Sonoma and Napa counties. Wine grapes are the second largest agricultural crop in the county (after strawberries), and the wine production they support creates a direct economic impact and a growing wine country vacation industry.
The county led the state in hemp cultivation in 2018 as hundreds of acres of the crop were grown in research partnerships. In 2019, nine agricultural research permits were still active. Sixteen commercial permits were issued before a temporary ban on new applications running through June 2020 was passed by the Board of Supervisors.

Future
In the future, SR 46 may be considered for a possible westward expansion of Interstate 40 via SR 58 from Barstow to Bakersfield, from Bakersfield to I-5 via Westside Parkway, and then following SR 46 to Paso Robles. SR 46 is slowly being upgraded to Interstate standards, minus overpasses between Interstate 5 and US Route 101.
