Because of its good schools, jobs and housing, the city was chosen in 2008 by CNNMoney.com as the fourth best place to live in the United States. In June 2008, the Federal Bureau of Investigation reported that Irvine had the lowest violent crime rate (four homicides, 17 rapes, 50 robberies and 55 aggravated assaults in 2006) among cities in the United States with populations of more than 100,000, and in August 2008 the Census Bureau ranked Irvine as having the seventh highest median income among cities in the United States with populations of more than 65,000.
Irvine is home to the University of California, Irvine (UCI), Concordia University, the Orange County Center of the University of Southern California, and the Irvine campuses of Alliant International University, California State University Fullerton, and Pepperdine University. Irvine Valley College, a community college, is also located in the city.
Irvine is home to a number of corporations, particularly in the technology sector.
The census of 2000 found there were 143,072 people, 51,199 households, and 34,354 families in the city. The population density is 1,196.2/km² (3,098.0/mi²), as of the census. There are 53,711 housing units at an average density of 449.1/km² (1,163.0/mi²). The racial makeup of the city is 61.06% White, 1.45% Black or African American, 0.18% Native American, 29.83% Asian American, 1.14% Pacific Islander, 2.54% from other races, and 4.82% from two or more races. 7.37% of the population are Hispanic or Latino of any race.
There are 51,199 households out of which 36.0% have children under the age of 18 living with them, 53.8% are married couples living together, 9.8% have a female householder with no husband present, and 32.9% are non-families. 22.8% of all households are made up of individuals and 5.0% have someone living alone who is 65 years of age or older.

According to 2007 Census Bureau estimates, the median income for a household in the city is $98,923, and the median income for a family is $111,455; these numbers make Irvine the seventh richest city in the USA, among cities with population 65,000 or higher. 9.1% of the population and 5.0% of families are below the poverty line.

In 2006, the median gross rent paid for housing was $1,660 a month. This was the highest of any place in the United States of more than 100,000 people. The skyrocketing high cost of housing is a major issue in Irvine and Orange County, as the city council faces pressure to approve future income-subsidized housing projects to meet the demands of working-class citizens.
Like much of Orange County, more resident voters are registered in the Republican Party than the Democratic Party . However, a majority on the city council, including the last three mayors, identify with the Democratic Party.
Streets and intersections owned by the city have trademark mahogany signage and are fiber optically linked to the city's Irvine Traffic Research and Control Center (ITRAC). Traffic cameras and ground sensors monitor the flow of traffic throughout the city and automatically adjust signal timing to line up traffic, allowing more vehicles to pass through fewer red lights. Several major highways pass through Irvine (Interstate 5, and Interstate 405 (California), California State Route 73, California State Route 133, California State Route 241, and California State Route 261). Major arteries through Irvine are built out widely and will run in a northeasterly direction with speed limits higher than 50 mph (80 km/h). As a result of the signal timing, wide streets, and road layout, Irvine's side streets are capable of handling a higher volume of traffic than other cities in Orange County.
Local bus routes are operated by the Orange County Transportation Authority. Additionally, Irvine is served by commuter rail at both the Irvine and Tustin stations of the Metrolink Orange County Line and the IEOC Line. OCTA is currently implementing a major service increase on the Orange County line, with trains running every 30 minutes. A four-story parking structure was recently completed at the Irvine station to coincide with the service increase.
At one time Irvine intended to build a tram / guideway, in February 2009 the city of Irvine canceled the project.[17] Initially plans were underway to connect the Orange County Great Park to the Irvine Spectrum Center and surrounding businesses with a fixed-route transit system, also stopping at the Irvine Transportation Center. In 2008, two possible routes were selected, but neither will be developed now. All of the 128,000,000 dollars in funding will be returned to the Measure M fund, and be available for other cities in Orange County.
The city of Irvine has recently begun operating its own mass-transit bus service called the iShuttle . This new bus service, which debuted on March 2008, consists of three routes linking the Tustin Metrolink station to the Irvine Business Complex area and John Wayne Airport. The service will be free to all passengers until January 1, 2009.
Irvine offers a system of bicycle lanes and trails to encourage the use of bikes as a means of transportation. There are 44.5 miles (71.6 km) of off-road bicycle trails and 282 miles (454 km) of on-road bicycle lanes in Irvine.
