California Population 2018


California is a large state on the west coast of the United States that is home to one of the world's most diverse population. Our current estimate for California's population in 2018 is 39.78 million. At the last official United States census carried out in 2010, the population of California was declared at 37,253,956 which makes the state the most populous by a wide margin over 2nd place Texas (28 million).

Much of the population is centered in several large cities. California contains the second largest city (Los Angeles), 3 of the largest 10 cities (Los Angeles, San Diego, and San Jose), and the largest county (Los Angeles County) in the United States.

California is projected to surpass 40 million residents by 2019, and represents approximately 1 out of every 8 US citizens. By 2050, the population is projected to surpass 50 million.

California is the 3rd largest state by area, putting its population density at 251.3 per square mile, which ranks 11th in the country. It is currently the 21st fastest growing state with a yearly growth rate of .61%. This growth rate has slowed in recent years, and is the lowest recorded.

Influences of California Population

California has a healthy natural growth rate and the gap between the birth rate and death rate is quite significant. Between 2000 and 2009, 5,058,440 births and 2,179,958 deaths resulted in a natural growth of 3,090,016.

Another significant factor is immigration: California had huge appeal in the days of the Gold Rush and that fact holds true today. Between those years of 2000 and 2009, the state enjoyed a net migration gain of 306,925 people. It’s also been estimated that up to approxmiately 6.3% of California’s population is made up of illegal immigrants.

California is larger than all but 35 countries in the world. It is also the second most populous national sub-entity, behind only Sao Paulo of Brazil.

California Population History

California was part of the region acquired from Mexico in 1848, and was admitted as a State on September 9, 1850 with essentially its present boundaries.

Although the 1850 census covered the whole State, the 1850 returns are incomplete; those for Contra Costa and Santa Clara Counties were lost before reaching Washington, and those for San Francisco County were destroyed by fire.

California Population Growth

The population of California in 2016 is growing at an above-average rate and an estimate carried out in 2015 suggests that there has been an increase from the 2010 Census figure of 37,253,956 to numbers in the region of 39,144,818.

In 1850 there were just 92,597 people living in California, but the gold rush of the mid-19th century was primarily responsible for a rise of over 300% to 379,994. The population of California continued to grow at a steadier rate but increases in excess of 50% between ten year censuses were not uncommon.

After World War II, the California population in 1950 was declared at 10,586,223, and it has been growing exponentially ever since. Ten years later in 1960, it was 15,717,204, and in 1970 that had grown to 19,953,134. From there, the numbers have been increasing at similar rates.

California has seen growth in every 10 year period of its history, and was officially determined to be most populous state at the 1970 Census, claiming the mantle from New York. It has remained the biggest state for nearly a half-century by posting consistenly high growth rates from year to year.

Population of California Projections

California is still growing and although it is difficult to track down any predictions, there is no reason to suggest that this growth will slow down. As such, could the population of California continue the trend and explode beyond the 40 million mark by the time of the next Census in 2020? If the current rate of growth continues, California's population may even approach 41 million by 2020.

The remaining ethnic groups consisted of Native American, Hispanic, Latino and others.
