This week, the California Department of Finance says the California has added 186,807 residents to the state for a total population of 39,927,315 as of January 1, 2019.  The slowest growth rate (0.47 percent) is the slowest in the States history.

This rate is driven by a significant decline in births, down by more than 18,000 over the previous year, as well and data reflecting lower student enrollment. Deaths continued an upward trend seen since 2010 as California’s “Baby Boomers” continue to age.

In terms of population growth from housing production not related to wildfires, the top five cities include: Lathrop (5.2 percent) in San Joaquin County, San Juan Bautista (4.8 percent) in San Benito County, Dublin (4.4 percent) in Alameda County, Irwindale (4.1 percent) in Los Angeles County, and Beaumont (4.0 percent) in Riverside County

In Contra Costa County, it saw a 0.7% growth with 1,155,89 with the City of Brentwood showing the most growth within the county with 2.4% with 63,662 residents. The city of Oakley was the next fastest growing city with a 2% gain with 41,759.

The report also highlights the California Wildfires:

  • The Camp Fire in Butte County was the most destructive wildfire in California history, with over 14,600 housing units destroyed. The fire destroyed almost 90 percent of the housing stock and displaced 83 percent of the population in the Town of Paradise, which suffered the loss of 11,371 housing units. The majority of the displaced persons relocated to the surrounding cities of Chico and Oroville, each adding more than 20 percent to their total populations.
  • With a population of 112,000, Chico saw the largest numeric change in the state, adding over 19,000 persons. With a population of 508,000 persons, Sacramento added over 7,400 persons. San Diego (1,421,000) added 6,200 persons, followed by Irvine (280,000) adding 6,100 persons. Santa Clarita (218,000) rounds out the top five cities by numeric growth with 5,700 new residents due to a large annexation from Los Angeles County.
  • Throughout the state, more than 23,700 housing units were demolished in 2018, with wildfires heavily influencing a number of areas. The counties with most housing loss due to fire include Butte (14,600), Shasta (900), Ventura (700), and Lake (300). The City of Malibu in Los Angeles County also lost close to 500 housing units due to wildfire.

Other Data:

  • Of the 14,235,000 housing units in California, 9,186,000 are single family and 4,490,000 are multi-family with 560,000 mobile homes. Multi-family housing growth outpaced single family housing by over 1,900 net units(“net” refers to new construction minus demolition), narrowing the difference from previous years but continuing a seven-year trend. Los Angeles led the state with 12,217multi-family units, comprising 73.9percent of their total housing growth, followed by San Diego (3,648 for 81.0 percent), San Francisco (2,277 for 99.5percent), and Irvine (1,439for 42.5percent).
  • Group quarters account for about 2 percent of the total state population (849,000).This population includes, among others, those living in college dorms (243,000) and in correctional facilities (215,500).In 2018, the group quarters population grew by just over 200 people or 0.03 percent. The college dormitory population grew the fastest at 3,800 (1.6 percent), the military group quarters population decreased by 2,700 (4.8 percent), local jails decreased by 260 (less than 1 percent) and state prisons decreased by 370 (less than 1 percent)

  1. Many of my friends have left California for Texas, Nevada, Idaho and some actually left the country for places like Monaco. These are people who had very high incomes and paid a lot in taxes. They just couldn’t take the traffic and crime problems here. Who can blame them!

    • Yeah so they go to places like that just to vote and make them just like California. Ruining the last few good places to live. Smart plan.

      • Not all Californians leaving this state are automatically liberals, jeff! Actually, most are conservatives who are sick and tired of this ONE-PARTY state and the problems created by the libs! Ever think of that?

  2. Oh please a decline in births, ya right. It’s people fleeing the state because of politics. California is drowning. Grab a raft and get out while you can

  3. The rate of population from 8 people to 7 billions people in 4500 years is 0.46% as from Noah’s time. At this same rate for the math-less anthropology, it would be more than 7 trillion people by 6000 years.

  4. I left because of the crime in Antioch
    And the taxes ..and that messed of stretch of road called hyway 4….
    If Antioch didn’t become little Oakland
    We would still have a good city
    It’s too bad what sec.8 did to Rivertown…
    I remember in the late.80’s and way early
    90’s how peaceful it was .. now you can literly get shot just walkn..out your front door… even in the goid area. Smh…

  5. Seems like the tech people are leaving in droves! Their start-ups did well. They made millions and now want to make sure this wasn’t spent on state taxes. Good for them! California is losing the top taxpayers. Let’s see how this will sit with the ridiculously overpaid state employees when they found out their pensions are gone!

    • What about ridiculously overpaid CITY employees? Look at what city managers are earning! Total insanity! This money comes from us, the taxpayers! These people indeed produce nothing but shovel paper and do a little electronically. Things have not gotten better. They’ve gotten worse and these yokels STILL earn in the quarter-of-a-million range annually. Ridiculous!
