Marin City is an unincorporated community and census-designated place (CDP) in Marin County, California, United States. As of the 2020 census, it had a population of 2,993, up from 2,666 in 2010. It is located northwest of downtown Sausalito, south-southeast of San Rafael, and about north of San Francisco from the Golden Gate Bridge, at an elevation of . Marin City was developed for housing starting in 1942, to accommodate wartime shipyard workers and other migrants to California. Among those were African Americans from the South in the Great Migration, which continued until 1970.

After World War II, the area became predominantly African-American, as White residents were able to move freely to private housing elsewhere in Marin County. Since the 1980s, additional development has changed the makeup of the population while providing more local jobs. While Marin City has not had a Black majority since the 1990s, Marin City's socioeconomic and racial makeup nevertheless contrasts with the largely White and wealthy population in Marin County overall, having a far higher Black population per capita and less than half the median household income.

Geography

Marin City is located in southern Marin County, about north of San Francisco. It is bordered to the southeast by the city of Sausalito and to the west by Tamalpais Valley, though there is no direct roadway connection to the latter community. The U.S. Route 101 freeway forms the northeastern edge of the community, beyond which is Richardson Bay, an arm of San Francisco Bay. The community is bordered to the southwest by the hills of the Golden Gate National Recreation Area.

History

Prior to World War II, this area was occupied by a dairy farm and a handful of families. Soon after war was declared on December 8, 1941, Marin City was rapidly built during 1942 in order to house 6,000 of the 20,000 workers who migrated from all over the United States, attracted by the defense jobs at Marinship, the Sausalito waterfront shipyard. A total of 93 liberty ships and tankers were built and launched from Marinship in fewer than three years.

Many of the African-American shipyard laborers who had migrated to the Bay Area from the South during the second phase of the Great Migration continued to live in Marin City after the war, either by choice or because many black families were restricted by local zoning from living in or buying homes in the towns surrounding Marin City. They became the core of the community after many of the other workers moved to other areas at the end of the war. During the war, African Americans comprised about 10 percent of Marin City's population. By the 1970s, African Americans comprised more than 75 percent of the population of Marin City, most of whom were descendants of the Marinship workers.

During the 1980s and 1990s there was considerable residential and commercial development in the community, including several new housing developments, apartment complexes, and condo developments. The commercial area was expanded, particularly with the construction of the Gateway Shopping Center in 1996, which displaced a locally renowned flea market. As of 2010, the community population was 38.9 percent white and 38.1 percent African American; nearly 14 percent were Hispanic of any race. In the early 21st century, Marin City residents and officials have begun to think about incorporating as a city.

Government The municipal authority for Marin City is the Marin City Community Services District (MCCSD), a multi-purpose California special district that is governed by a publicly elected five-member board of directors. It is administered by a district manager and staff. Chartered in 1958, the MCCSD is responsible for providing services in the areas of parks and recreation, street lighting, recycling and refuse removal.Marin City Community Services District official site, accessed November 8, 2022

Demographic trends Until the 1990s, the majority of Marin City's population was Black. The 2000 census showed the Black population at about 44%, for the first time no longer the majority, but nevertheless the largest single group. This reflected a stable black population of about 1,000 individuals, but with large growth in the overall population of Marin City, largely from White, Latino, and Asian newcomers. The 2010 census showed a similar trend, with a stable Black population being the largest single group at about 37%. The 2020 census showed a decline in the Black population in both absolute numbers and in percentage of the population, now at about 26.5%, making them the second largest group in Marin City after the White population, who make up about 34% of the CDP's population. This reflected a county-wide trend in which the Black population of Marin declined even as the Latino and Asian population of the county grew, with advocates noting that Black residents in particular struggle to stay in Marin. A Marin City community activist noted, however, that the community is 66% people of color.

Housing

Homes sold in Marin City are often labeled as being located in Sausalito since Marin City shares the 94965 ZIP Code, the 331 and 332 telephone prefixes, and Sausalito Marin City School District with its close neighbor Sausalito. Most of the housing in Marin City was developed in the 1970s, '80s and '90s after much of the temporary Marinship housing put up in 1942 had been razed.

Business

Once famous for the Marin City Flea Market which was forcibly closed in the mid-1990s, despite community protest, to make way for the Gateway Shopping Center, the MCCSD had planned to launch the smaller-scale Marin City Market Fest on selected Saturdays in the summer of 2006.
