California Population 2018
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 made the state the most populous in the country.
However, the vast area that California encompasses means that in terms of population density, with 251.3 people for every square mile, it ranks only 11th in the nation.
It is currently the 17th fastest growing state with a yearly growth rate of .90%.
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 aliens.
Putting population in perspective
The end result when taking all these figures into account is a population that is simply huge. Based on current estimates, California is larger than all but 34 countries in the world. It is also the second most populous national sub-entity, behind only Sao Paulo of Brazil.
