Los Angeles still ranks No. 1 for the most populated in the state, with 3.7 million people, which is a 2-percent increase.
L.A. was followed by San Diego with a population of 1.3 million, and San Jose and San Francisco came in at third and fourth respectively.
One of the biggest surprises of the census report was that Fresno, with 494,000 people, grew by 15 percent since the 2000 census.
For most populated counties in the state, Los Angeles County ranked No. 1, with 9.8 million residents, up 3 percent since 2000. Other top counties include San Diego with 3 million - a 10-percent increase - followed by Orange County and San Bernardino.
But the real newsmaker was Riverside County. At 2.1 million residents, Riverside County saw a 41-percent increase in the past 10 years.
As for demographics, the latest census figures showed that Latinos and Asians accounted for virtually all of California's population growth over this last decade - Latinos by 28 percent and Asians by 31 percent.
Non-Hispanic whites, meanwhile, saw their numbers decrease by 5 percent, while the state's black population dropped by 1 percent.
In terms of politics, even though California grew by 10 percent to 37 million, the state did not pick up any additional congressional seats. That's the first time that's ever happened.
