It is named after the Merced River, which flows nearby.

Merced, known as the "Gateway to Yosemite", is less than two hours by automobile from Yosemite National Park to the east and Monterey Bay, the Pacific Ocean, and multiple beaches to the west. The community is served by the passenger rail service Amtrak, a minor, heavily subsidized airline through Merced Regional Airport, and three bus lines. It is approximately 110 miles (180 km) from Sacramento, 130 miles (210 km) from San Francisco, 55 miles (89 km) from Fresno, and 270 miles (430 km) from Los Angeles.

The first Merced post office opened in 1870. Merced incorporated in 1889 and now operates under the council-manager form of government.

During World War II, the Merced County fairgrounds were the site of a temporary "assembly center" where Japanese Americans were detained after being removed from their West Coast homes under Executive Order 9066. 4,669 men, women and children from central California (with most coming from Merced County) were confined in the Merced Assembly Center from May 6 to September 15, 1942, when they were transferred to the more permanent Granada internment camp in Colorado.

Home prices have since rebounded, with the median sale price in April 2018 at $247,000. The current average being $358,000. Terry Ruscoe of Merced-Yosemite Realty, noted investors from outside of the Valley were helping to drive up home prices. Ruscoe said, "A tremendous amount of out-of-town buyers. Our primary client comes from the LA area or the Bay Area. We see a lot of them coming in and buying properties, even coming in now when the prices are moving up quickly because they know they can rent those."

The metro area went to a 14.2% unemployment rate in December 2013. Having since recovered to a rate of 8.7% in April 2018. Some efforts have been directed towards diversifying its economy and are showing a lowering trend in the overall unemployment rate, according to the Bureau of Labor Statistics.

During the Great Recession Merced suffered one of the greatest property price collapses in the country and house prices at the end of 2009 had fallen to 1998 levels, according to Zillow, making housing affordable compared to many other California locations.

The economy has traditionally relied upon agribusiness and upon the presence of Castle Air Force Base. Over the past twenty years, more diversified industry has entered the area, including printing, fiberglass boat building, warehousing and distribution, and packaging industries.

In September 1995, Castle Air Force Base closed after phasing down over the previous three years. This affected residential real estate and some sectors of the retail and service economies, but overall retail continued to increase. Industrial development is increasing in the area. It is now known as the Castle Airport Aviation and Development Center. The Castle Air Museum remains at the site.

Escaping persecution from Communist forces after the Laotian Civil War, Hmong refugees from Laos moved to the United States in the 1970s and '80s, first settling in Merced and other areas in the Central Valley of California. The Hmong could not initially take part in farming like they had expected, as the land was owned by other people. They could not get high end agricultural jobs because they did not speak sufficient English and Mexican migrants already held low end agricultural jobs. As such, a great many of Merced's Hmong collected social services and Hmong gangs arose, prompting other residents to perceive them as being the cause of economic troubles. As the Hmong settlement matured and the Hmong children gained English language skills, the town's overall attitude began to be more accepting of the Hmong community.

This acceptance is reflected in various services provided to the Hmong community. This includes the Merced Lao Family Community Inc., a nonprofit organization that provides social services to Hmong people, the Merced Department of Public Health's MATCH (Multidisciplinary Approach to Cross-Cultural Health) program, intending to draw Hmong patients into the health care system, a body of Hmong-speaking faculty and paraprofessionals (including college classes on Hmong culture and language), and media outlets for the Hmong community—cable television channel Channel 11 broadcasts programming to the Hmong community twice per week and radio station KBIF 900 AM airs programming oriented towards Hmong people.

While Merced has historically had a proportionally large portion of Hmong (in 1997, 12,000 of Merced's 61,000 residents were Hmong), demographic shifts have reduced this. The Personal Responsibility and Work Opportunity Act of 1996 prompted a move of some Hmong to Minnesota, North Carolina, and Wisconsin. More recently, many Hmong have gone to Alaska to work in crabbing and fishing industries that require little proficiency in English.

Through the years, Merced County has recognized many historic milestones. Some of those essential moments include the rise of Merced's first Black mayor, Sam Pipes in 1983 and the visit by first lady Michelle Obama to UC Merced for the university's 2009 commencement.

There's also the story of the late Charles Ogletree, a Merced native who rose from poverty to become a respected Harvard Law professor. Ogletree taught both Barack and Michelle Obama at Harvard; he remained close to Barack Obama throughout his apolitical career. Ogletree wrote opinion pieces on the state of race in the United States for major publications. Ogletree also served as the moderator for a panel discussion on civil rights in baseball on March 28, 2008, that accompanied the second annual Major League Baseball civil rights exhibition game the following day between the New York Mets and the Chicago White Sox.

In 2010, Latinos became a majority population in Merced and Merced County as the agricultural industry brought in migrant farm laborers. The area's affordable housing prices attracted both Latino and Asian immigrants. Merced has large Asian-American (e.g. Hmong, followed by Chinese, Vietnamese, Laotian, Cambodian, Filipino, Thai, Korean and Asian Indian) populations relative to the city and county's population size.

In Merced County, Black history goes back to before the Civil War. According to historian Sarah Lim, during the mid-1800s Blacks came to this region and California as enslaved persons, while others arrived as free settlers. The 2011 census reported that 9,837 Black or African Americans lived in Merced County

In 2021, Merced had approximately 4,000 violent crimes occur within the city. This means that with a population of just 89,303 people, in 2021, individuals had approximately a 4.5% chance of falling victim to a crime while living-in or visiting Merced. Of the crimes that occurred, roughly 1,200 were physical (such as assault, rape or homicide) and 2,500 were property-related (e.g. burglary and theft). However, these crimes occurring in 2021 resulted in 13 fatalities. With its high crime rate, Merced is considered one of the "50 most dangerous" Californian cities to live in.

Merced has a history of minor league baseball including the California League Merced Bears (1940s) and Atwater Angels (1970s) in nearby Atwater, California.

Amtrak San Joaquins provides passenger service.

The Yosemite Valley Railroad ran from Merced between 1907 and 1945.

The California High-Speed Rail Authority February 2016 draft business plan, outlined the Merced station as not beginning service at the same time as the initial San Jose to Bakersfield route in 2025, but would likely open in 2029 instead. This would make the leg between the Central Valley and Pacheco Pass the first to be constructed. The Merced City Council vigorously opposed the delay in their city's station opening, noting Merced's volume of commuters seeking high-speed rail to access jobs in Silicon Valley. In response, the April 2016 revisions to the business plan indeed included Merced in the initial construction segment, initially as a single-track spur connecting only to the westbound track to the Bay Area, with build out of the full Wye happening later. The system will run from San Francisco to the Los Angeles basin in under three hours at speeds capable of over 200 miles per hour. In August 2022, the CAHSRA announced that it had received a $25,000,000 RAISE Grant to advance design work from Madera to Merced.

Sample trips in the California High Speed rail would include:
