In the 2000 census, the Westside (as defined by the Los Angeles Times) had a population of 529,427. The areas within the city of Los Angeles that Los Angeles Almanac recognized as part of the Westside had a population of 413,351. Originally, the Westside was overwhelmingly white, but it has grown more ethnically diverse. In 2000, non-Hispanic whites made up 63% of the population. Economic levels vary from middle class to upper class, and a majority of the wealthiest communities in Los Angeles County are located on the Westside.
The Westside rivals downtown Los Angeles for the number of people commuting to it from other areas, in particular the San Fernando Valley to the north and the South Bay to the south.
The proposed Pacific Coast, Beverly Hills, and Laurel Canyon freeways went unbuilt in the face of massive community opposition. A great deal of development took place in anticipation of these roadways' construction, resulting in significant congestion on the area's surface streets during peak rush hour. Proposals to widen existing freeways have been explored, and, more recently, a previous proposal to turn Pico and Olympic boulevards into one-way streets has been revived. The area is well covered by several Metro Rapid bus lines that traverse most major thoroughfares, but the routes are often extremely slow due to traffic congestion. Construction has commenced on the light rail Expo Line (Los Angeles Metro) that will connect Santa Monica to Downtown Los Angeles by 2015.
Los Angeles International Airport (LAX), the principal airport of the Greater Los Angeles area, is located in the southern Westside neighborhood of Westchester and is among of the busiest airports in the world in terms of passenger traffic and cargo handled.
