what percentage of the united states lives in california
Demographics of California As of 2006, California had an estimated population of 37,172,015, more than 12 percent of the U.S. population. This includes a natural increase since the last census of 1,557,112 people ( i.e. 2,781,539 births minus 1,224,427 deaths) and an increase due to net migration of 751,419 people. Immigration resulted in a net increase of 1,415,879 people, and migration from within the U.S. resulted in a net decrease of 564,100 people. California is the 13th fastest-growing state. As of 2008, the total fertility rate was 2.15.[11] The most recent census reports the population of California as 39,144,818.
California In 1848, only one week before the official American annexation of the area, gold was discovered in California, this being an event which was to forever alter both the state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Chinese and other immigrants during the great California Gold Rush. By the time of California's application to the US Congress for statehood in 1850, the settler population of California had multiplied to 100,000. By 1854 over 300,000 settlers had come.[59] Between 1847 and 1870, the population of San Francisco increased from 500 to 150,000.[60] California was suddenly no longer a sparsely populated backwater, but seemingly overnight it had grown into a major US population center.
