Oakland is a major West Coast port, and is home to several major corporations including Kaiser Permanente and Clorox, as well as corporate headquarters for nationwide businesses like Dreyer's and Cost Plus World Markets. Oakland is a major hub city for the Bay Area subregion collectively called the East Bay.

An analysis by the Urban Institute of U.S. Census 2000 numbers showed that Oakland has the third-highest concentration of gays and lesbians among the 50 largest U.S. cities, behind San Francisco and Seattle. Census data show that, among incorporated areas that have at least 500 female couples, Oakland has the nation's largest percent per capita. In 2000, Oakland counted 2650 lesbian couples; one in every 41 Oakland couples listed themselves as a same-sex female partnership.
In 2000, Oakland's population was reported as 25.0 percent under the age of 18, 9.7 percent from 18 to 24, 34.0 percent from 25 to 44, 20.9 percent from 45 to 64, and 10.5 percent who were 65 years of age or older.

Residents of Oakland utilize three major airports in the San Francisco Bay Area: Oakland International Airport, San Francisco International Airport, and San Jose International Airport. Oakland International Airport, located within the city limits of Oakland, is 4 miles (6 km) south of downtown Oakland and serves domestic and international destinations. Southwest Airlines has a large presence at the airport and has been flying there since 1989. AC Transit provides service to the airport from Oakland neighborhoods and the Coliseum Bart Station on its "50" line for fare of $1.75, and aboard its "805" "All Nighter" bus all the way to downtown Oakland where other All Nighter connections are available. AirBART provides more frequent shuttle bus service directly to the airport for a higher fare of $3.00.
Oakland is served by several major highways: Interstate 80 (Eastshore Freeway), Interstate 580 (MacArthur Freeway), Interstate 880 (Nimitz Freeway), Interstate 980 (Williams Freeway), State Route 13 (Warren Freeway) and State Route 24 (Grove Shafter Freeway). A stub of a planned freeway was constructed at the High Street exit from the Nimitz Freeway, but that freeway extension plan was abandoned.
In 1989, the Loma Prieta earthquake caused the Cypress Street Viaduct double-deck segment of the Nimitz Freeway I-880 to collapse, killing 42 people. The old freeway segment had passed right through the middle of West Oakland, forming a barrier between West Oakland neighborhoods. Following the earthquake, this section of the Nimitz Freeway was rerouted around the perimeter of West Oakland and rebuilt in 1999. The east span of the San Francisco – Oakland Bay Bridge also suffered damage from the quake when a 50-foot (15 m) section of the upper deck collapsed onto the lower deck; the damaged section was repaired one month after the earthquake. As a result of the earthquake, a significant seismic retrofit was performed on the western span of the Bay Bridge, and the eastern span is scheduled for replacement, with the new span projected to be completed in 2014.
Two underwater tunnels, the Webster and Posey Tubes, connect the main island of Alameda to Downtown Oakland, coming above ground in Chinatown. In addition, the Park Street, Fruitvale, and High Street bridges connect Alameda to East Oakland over the Oakland Estuary.
In the hills, the Leimert Bridge crosses Dimond Canyon, connecting the Oakmore neighborhood to Park Boulevard. The Caldecott Tunnel carries Highway 24 through the Berkeley Hills, connecting central Contra Costa County to Oakland. The Caldecott has three bores, with a fourth one planned.
Pavement conditions are "at risk" on the 1,974 "total lane miles" of Oakland streets, many of which are wide, multi-lane arterial boulevards. Between 2005 and 2007 Oakland streets were ranked poorly in the results of an Metropolitan Transportation Commission (MTC) study released on January 5, 2009. Overall, Oakland streets scored in the "at risk" category of its Pavement Condition Index (PCI) over a three year moving average, resulting in hazardous pavement conditions for bicyclists and the probability of increased vehicle suspension and other maintenance costs for all road users. The MTC asserts that major repairs cost five to ten times more than routine maintenance, and scored Oakland streets overall as past the point where rehabilitation could have been used to prevent rapid deterioration.
Bus transit service in Oakland and the inner East Bay is provided by the Alameda and Contra Costa Transit District, AC Transit. The district originated in 1958 after the conspiratorial dissolution of the Key System of streetcars which followed the National City Lines (NCL) holding company acquisition of 64% of its stock in 1946. In the 1948 federal case "United States v. National City Lines Inc.," the defendants were found guilty on a count of conspiring to monopolize the provision of parts and supplies to their subsidiary companies. The companies were each fined $5,000, and the directors were each fined one dollar. The verdicts were upheld on appeal in 1951.
Many AC Transit lines follow old Key System routes. Currently the district is planning a full scale Bus Rapid Transit line for the 1 line on the International Boulevard and Telegraph Avenue corridors.
The metropolitan area is served by Bay Area Rapid Transit (BART) from eight stations in Oakland. The system has headquarters in Oakland, with major transfer hubs at MacArthur and Oakland City Center/12th Street stations. BART's headquarters was located in a building above the Lake Merritt Station until 2006, when it relocated to the Kaiser Center due to seismic safety concerns.
The city has regional and long distance passenger train service provided by Amtrak, with a station located blocks from Jack London Square served by the Amtrak Capitol Corridor, Coast Starlight and San Joaquins train routes. Capitol Corridor trains also stop at a second, newer Oakland Coliseum station. Amtrak's California Zephyr has its western terminus at Emeryville, CA station.
The Alameda / Oakland Ferry operates ferry service from Jack London Square to Alameda, San Francisco, and Angel Island.
Oakland licenses taxi-cabs, and has zoned cab stands in its downtown. There is currently a movement underway to increase the supply of taxis by increasing the number of taxi licenses. A bicycle pedi-cab service operates downtown.
Freight service, which consists primarily of moving shipping containers to and from the Port of Oakland, is provided today by Union Pacific Railroad (UP), and to a lesser extent by BNSF Railway (which now shares the tracks of the UP between Richmond and Oakland).
Historically, Oakland was served by several railroads. Besides the transcontinental line of the Southern Pacific, there was also the Santa Fe (whose Oakland terminal was actually in Emeryville), the Western Pacific Railroad (who built a pier adjacent to the SP's), and the Sacramento Northern Railroad (eventually absorbed by the Western Pacific which in turn was absorbed by UP in 1983).
As one of the three major ports on the West Coast of the United States, the Port of Oakland is the largest seaport on San Francisco Bay and the fourth busiest container port in the United States. It was one of the earliest seaports to switch to containerization and to intermodal container transfer, thereby displacing the Port of San Francisco which never modernized its waterfront. One of the earlier limitations to growth was the inability to transfer containers to rail lines, all cranes historically operating between ocean vessels and trucks. In the 1980s the Port of Oakland began the evaluation of development of an intermodal container transfer capability, i.e. facilities that now allow trans-loading of containers from vessels to either trucks or rail modes.
Despite large tax breaks East Bay nonprofit hospitals receive for community service, public hospitals such as Highland devote a much larger portion of their operating expenses to charity care.
Summit Medical Center was a previous merger with Samuel Merritt Medical Center and Providence Medical Center in the 1990s. Peralta Hospital earlier had merged with Samuel Merritt Hospital. Oakland Hospital in the Fruitvale district closed in the 1990s. Naval Hospital Oakland (Oak Knoll Naval Hospital) closed during the military Base Realignment and Closure of 1993.
Oakland has nine sister cities:
