Berkeley is the site of the University of California, Berkeley, the oldest of the University of California system, and the Lawrence Berkeley National Laboratory. It is also home to the Graduate Theological Union. The city is noted as one of the most politically liberal in the nation, with one study placing it as the third most liberal city in the United States.
As of the census of 2000, there were 102,743 people, 44,955 households, and 18,656 families residing in the city. The population density was 9,823.3 people per square mile (3,792.5/km²), one of the highest in California. There were 46,875 housing units at an average density of 4,481.8/sq mi (1,730.3/km²). The racial makeup of the city was 59.17% White, 16.39% Asian, 13.63% Black or African American, 0.45% Native American, 0.14% Pacific Islander, 4.64% from other races, and 5.57% from two or more races. 9.73% of the population were Hispanic or Latino of any race. Non-Hispanic whites accounted for 55.18% of the city's population. 7.3% were of German, 7.2% English and 6.3% Irish ancestry according to Census 2000. 73.1% spoke English, 8.3% Spanish, 4.5% Chinese or Mandarin, 1.6% French, 1.2% Korean, 1.1% Japanese and 1.0% German as their first language.
There were 44,955 households out of which 17.8% had children under the age of 18 living with them, 28.9% were married couples living together, 9.5% had a female householder with no husband present, and 58.5% were non-families and/or unmarried couples. 38.1% of all households were made up of individuals and 7.9% had someone living alone who was 65 years of age or older. The average household size was 2.16 and the average family size was 2.84.
In the city the population was spread out with 14.1% under the age of 18, 21.6% from 18 to 24, 31.8% from 25 to 44, 22.3% from 45 to 64, and 10.2% who were 65 years of age or older. The median age was 32 years. For every 100 females there were 96.5 males. For every 100 females age 18 and over, there were 95.1 males.
According to a 2007 estimate, the median income for a household in the city was $57,189, and the median income for a family was $93,297.[3] Males had a median income of $50,789 versus $40,623 for females. The per capita income for the city was $30,477. About 8.3% of families and 20.0% of the population were below the poverty line, including 13.4% of those under age 18 and 7.9% of those age 65 or over.
Berkeley is served by Amtrak (Capitol Corridor), AC Transit, BART (Downtown Berkeley Station, North Berkeley, and Ashby Station) and bus shuttles operated by major employers including UC Berkeley and Lawrence Berkeley National Laboratory. The Eastshore Freeway (Interstate 80 and Interstate 580) runs along the bay shoreline. Each day there is an influx of thousands of cars into the city by commuting UC faculty, staff and students, making parking for more than a few hours an expensive proposition.
Berkeley has one of the highest rates of bicycle and pedestrian commuting in the nation. Berkeley is the safest city of its size in California for pedestrians and cyclists, considering the number of injuries per pedestrian and cyclist, rather than per capita.
Berkeley has modified its original grid roadway structure through use of diverters and barriers, moving most traffic out of neighborhoods and onto arterial streets (visitors often find this confusing, because the diverters are not shown on all maps). Berkeley maintains a separate grid of arterial streets for bicycles, called Bicycle Boulevards, with bike lanes and lower amounts of car traffic than the major streets to which they often run parallel.
Berkeley hosts a car sharing network run by City CarShare. Rather than owning (and parking) their own cars, members share a group of cars parked nearby. Web- and telephone-based reservation systems keep track of hours and charges. Several "pods" (points of departure where cars are kept) exist throughout the city, in several downtown locations, at the Ashby and North Berkeley BART stations, and at various other locations in Berkeley (and other cities in the region). Using alternative transportation is encouraged.
Berkeley has had recurring problems with parking meters. In 1999, over 2,400 Berkeley meters were jammed, smashed, or sawed apart. Starting in 2005 and continuing into 2006, Berkeley began to phase out mechanical meters in favor of more centralized electronic meters.
The first commuter service to San Francisco was provided by the Central Pacific's Berkeley Branch Railroad, a standard gauge steam railroad which terminated in downtown Berkeley, and connected in Emeryville (at a locale then known as "Shellmound") with trains to the Oakland ferry pier as well as with the Central Pacific main line starting in 1876. The Berkeley Branch line was extended from Shattuck and University to Vine Street ("Berryman's Station") in 1878. Starting in 1882, Berkeley trains ran directly to the Oakland Pier. In the 1880s, Southern Pacific assumed operations of the Berkeley Branch. In 1911, Southern Pacific electrified this line and the several others it constructed in Berkeley, creating its East Bay Electric Lines division. The huge and heavy cars specially built for these lines came to be called the "Red Trains" or the "Big Red Cars". The Shattuck line was extended and connected with two other Berkeley lines (the Ninth Street Line and the California Street line) at Solano and Colusa (the "Colusa Wye"). It was at this time that the Northbrae Tunnel and the Rose Street Undercrossing were constructed, both of which still exist (the Rose Street Undercrossing is not accessible to the public, being situated between what is now two backyards). The last Red Trains ran in July, 1941.
The first electric rail service in Berkeley was provided by several small streetcar companies starting in 1891. Most of these were eventually bought up by the Key System of Francis "Borax" Smith who added lines and improved equipment. The Key System's streetcars were operated by its East Bay Street Railways division. Principal lines in Berkeley ran on Euclid, The Arlington, College, Telegraph, Shattuck, San Pablo, University, and Grove (today's Martin Luther King Jr. Way). The last streetcars ran in 1948, replaced by buses.
The first electric commuter interurban-type trains to San Francisco from Berkeley were put in operation by the Key System in 1903, several years before the Southern Pacific electrified its steam commuter lines. Like the SP, Key trains ran to a pier serviced by the Key's own fleet of ferryboats which also docked at the Ferry Building in San Francisco. After the Bay Bridge was built, the Key trains ran to the Transbay Terminal in San Francisco, sharing tracks on the lower deck of the Bay Bridge with the SP's red trains and the Sacramento Northern Railroad. It was at this time that the Key trains acquired their letter designations, which were later preserved by Key's public successor, AC Transit. Today's F bus is the successor of the F train. Likewise, the E, G and the H. Before the Bridge, these lines were simply the Shattuck Avenue Line, the Claremont Line, the Westbrae Line, and the Sacramento Street Line, respectively.
After the Southern Pacific abandoned transbay service in 1941, the Key System acquired the rights to use its tracks and catenary on Shattuck north of Ward Street and through the Northbrae Tunnel to The Alameda for the F-train. The SP tracks along Monterey Avenue as far as Colusa had been acquired by the Key System in 1933 for the H-train, but were abandoned in 1941. The Key System trains stopped running in April 1958. In 1963, the Northbrae Tunnel was opened to auto traffic.
