In 2010 the San Fernando Valley (CCD) population stood at 1,749,894, making it the fifth largest identifiable metro "place" in the nation when compared to the top ten U.S. cities. Cascades The Valley has a greater populatian than Philadelphia, Phoenix, San Antonio, San Diego, Dallas or San Jose. It comprises 48 percent of the land in the City of Los Angeles, and 45 percent of the population. The City of Los Angeles is bifurcated by the Santa Monica mountain range, which separates its central city area from its valley area to the north.

To the south the city is jurisdictionally connected to the Port of Los Angeles, and to the Wilmington/San Pedro/Harbor City communities, by the slender "Shoestring Addition" of 1911. Most of the Valley was annexed by Los Angeles in 1915, as a means to gain access to Owens Valley water flowing from the newly-constructed Los Angeles Aqueduct. The aqueduct termintated in Sylmar in the northeast valley. As it turned out, the Valley is situated over a huge underground aquifer that the city needed for storage; and the Valley's massive agricultural range stood to benefit greatly from access to more water. The 1915 vote for annexation was 681 to 25.

The San Fernando Valley Census County Division rose out of a movement to better define the Valley area of Los Angeles City and County. The area is geographically distinct, but is made up of several cities and portions of cities including the cities of Burbank, Glendale, San Fernando, Hidden Hills and Calabasas. The Valley is equal in size to seventy percent of the land area of the City of Los Angeles.
