As of the 2020 United States census, its population was 14,016. Situated at roughly 2,500 ft in elevation in the western foothills of the Sierra Nevada mountain range, this northern Gold Country city is 57 mi by car from Sacramento and 88 mi west of Reno.

• Illustration — Grass Valley geological map, and the location of the North Star, Empire, and Maryland mines Grass Valley, which was originally known as Boston Ravine and later named Centerville, dates from the California Gold Rush, as does nearby Nevada City. Gold was discovered at Gold Hill in October 1850 and population grew around the mine. When a post office was established in 1851, it was renamed Grass Valley the next year for unknown reasons. The town was incorporated in 1860. The essential history of Grass Valley mining belongs to the Grass Valley Mining District's main mines—the North Star, Empire, and Idaho-Maryland—for continuous production over a span of years. From 1868 until 1900, the Idaho-Maryland mine was the most productive in the district. From 1900 until 1925, the North Star and the Empire produced the most gold in the county. In 1932, the Empire and North Star were physically connected at the 4600-foot level and 5300-foot level. Grass Valley has the Empire Mine and North Star Mine, two of California's richest mines. George Starr, manager of the Empire Mine, and William Bowers Bourn II, the owner, donated mine property which became Memorial Park. Wiliam Bourn Jr. had taken over management of the Empire Mine in 1878 after his father's death, replacing water power with steam. In 1884, Bourn purchased and rejuvenated the North Star mine. The Idaho and Maryland mines were consolidated by Samuel P. Dorsey in 1893. In 1925, Errol MacBoyle acquired the Idaho-Maryland. By 1938, the Idaho-Maryland was the second largest gold producer in the country. However, gold mining operations in the area ended during WWII, due to War Production Board Limitation Order 208. After the war, renewed operations were attempted, but according to Gage McKinney, "by the mid-1950s mining was no longer profitable in what had been the richest gold mining district in California." Many of those who came to settle in Grass Valley were tin miners from Cornwall, United Kingdom. Most arrived between 1860 and 1895, composing three quarters of Grass Valley's population. After the Civil War ended and news of death of President Lincoln many in the town rejoiced. When these acts of celebration were heard by 1st Battalion of Native Cavalry they sent out a detachment of 25 men. Commanded by Second Lieutenant M. E. Jimenez, the detachment rode into town and got into a skirmish with 10 locals. Two troopers were wounded in the action. The soldiers arrested all 10 of the rebels and took them to Camp Low. Grass Valley still holds on to its Cornish heritage, with events such as its annual Cornish Christmas and St. Piran's Day celebrations. Cornish pasties are a local favorite dish with a few restaurants in town specializing in recipes handed down from the original immigrant generation. Grass Valley is also twinned with Bodmin in Cornwall (UK). There was formerly a (short-lived) Roman Catholic Diocese of Grass Valley in 1868–1884, later relocated in Sacramento (and now a titular see). The Grass Valley Kmart store, opened in 1981, was the last remaining location in California at the time that it closed in 2021. It is now a Target department store.

According to the United States Census Bureau, the city has an area of 4.7 sqmi, all of it land. A variety of igneous and metamorphic rock supports Grass Valley. Granitic rock such as quartz diorite underlies the downtown core and extends south along Highway 49. Metavolcanic rock and diabase underlie areas around the granitic zone. Neighborhoods around Nevada County Golf Course and Sierra Nevada Memorial Hospital are underlain by ultramafic rock which supports infertile soils of the Dubakella series. Here the vegetation is sparse considering the high average annual precipitation, with much grassland, and forested areas are often dominated by several species of oaks and the crooked, thin-crowned gray pine. Luxuriant forest dominated by straight, dense ponderosa pine inhabits the more fertile soils, which include Musick series on granitic rock and Sites series on mafic or metamorphic rock.

Grass Valley has a hot-summer Mediterranean climate (Köppen Csa) with warm to hot, dry summers and wet, cool, rainy winters. Summer is very dry, but thunderstorms may occur. Rainfall averages over 50 in per year, in extreme contrast with the semi-arid valley below, which average as low as 12 in in some parts. The high rainfall also gives the area green vegetation typical of an oceanic climate. This contributes to a heavy fuel-loading of brush and grass, which dry out during the near-rainless summer, posing a wildfire hazard. Winters are cool but rarely cold. There are at least one or more snow events per year, often in the late winter. Frequent and large disruptive winter storms occur some years, while other years may have little to no snow. Less marine influence means that snow tends to occur more irregularly than some communities at similar elevation nearby to the south, such as Pollock Pines. Over the course of a year, 36.4 days of 90 °F or hotter and 0.9 days of 100 °F or hotter occur, with 61.4 days with minimum of 32 °F or colder.

• Illustration — Shops on Main Street The combined communities of Grass Valley and Nevada City have a fairly diversified economy. The Gold Rush days left a historical legacy and tourism and the related services sector constitute the bulk of the local economy. Nevada County is sometimes thought of as a bedroom community for families, with significant numbers of retirees. Those of working age often commute to Sacramento Valley cities to work, especially to job centers in Roseville, Yuba City, and Sacramento; and sometimes as far as the Bay Area. These commutes are quite long, resulting in many residents becoming super commuters. Many of those who do not commute to the Sacramento Valley work locally in retail, wholesale, trade, engineering, manufacturing, construction, and other businesses, as well in local and state government. A significant number of high-tech electronics companies are in the area. Another significant sector of the local economy is agriculture, as the soil in Nevada County is quite fertile. Around the time of the Gold Rush, farmers planted orchards, vegetables, and other produce as ranchers brought in cattle, sheep, and other livestock. While the proportion of land dedicated to agriculture has significantly decreased over the last few decades, agriculture continues to be an important aspect of the local economy, including organic agricultural products. Nevada County has also become known for its growing wine industry. Major employers in Grass Valley include Nevada Union High School, Nevada Irrigation District, Sierra Nevada Memorial Hospital, Golden Empire Nursing and Rehab Center, AJA Video Systems, Inc. and Briar Patch Food Co-op. The Grass Valley Group is a media technology research and development company founded in the city in 1959.
