Urban Growth Boom

California experienced unprecedented military, technological, and industrial growth before, during, and after the war, which in turn led to massive increases in migration, population, jobs, and the development of sprawling industrial, urban, and suburban areas. While jobs were plentiful in California cities during and after the war, housing was not. So great was the need for housing that military barracks, Quonset huts, trailers, and other quick-built facilities were used for housing.

On the eve of the war, California's population had already doubled since the 1920s, to 3.4 million. By 1962, California had become the most populous state in the union and had grown to 19.95 million by 1970. Approximately six million housing units were constructed in California during the thirty year period following World War II, which was made possible by government regulations, increasing wealth, more job opportunities, and new, quick methods of construction. Along with the population growth came the need for more educational facilities, shopping areas, and means of transportation. Hundreds of miles of freeways and roads were constructed to accommodate the tremendous growth in housing and new types of postindustrial and technology based industries.
