Here's the actual California Department of Finance report, which I think is very interesting:
STATE’S POPULATION INCREASES WHILE HOUSING GROWS
PER NEW STATE DEMOGRAPHIC REPORT
Some tidbits:
The population increased in 31 counties, largely in the Bay Area, Central Valley, and the Inland Empire. Los Angeles County and Orange County grew by 0.05 and 0.31 percent in population, respectively.
• Five counties had growth above one percent: Sutter (1.9 percent), Imperial (1.8 percent), Glenn (1.4 percent), Yuba (1.1 percent), and San Benito (1.1 percent), due to housing gains. The next largest in percentage growth were San Joaquin (0.96 percent), Madera (0.9 percent), Tulare (0.9 percent), Monterey (0.8 percent), and Merced (0.7 percent) counties.
• Nine of the ten Counties with populations over 1 million saw increases in population comprising 72 percent of the state’s total population. Riverside County led with an increase of 13,800.
County housing highlights include:
• Yuba had the highest housing growth (2.0 percent) of all counties, followed by: Placer, Madera, Butte, San Benito, Glenn, Tulare, Yolo, Riverside, and Solano.
• Eleven counties gained housing at or above 1.0 percent.
• Ranked by net housing gains, Los Angeles (21,698), San Diego (5,720), Unincorporated Riverside County (2,458), San Francisco (2,277), and Oakland (1,972) added the most housing units in 2023.
• Larger densely populated urban areas built most of the multi-family housing throughout the state. Los Angeles led the state gaining 14,207 multi-family units, comprising 65.5 percent of their net housing growth, followed by San Diego (4,255 for 74.4 percent), San Francisco (2,019 for 88.7 percent), and Oakland (1,674 for 84.9 percent).
• Conversely, single family housing is more likely to be built further inland in typically more suburban cities. Cities with a high proportion of single-family growth include Roseville (1,315 for 96.3 percent), Menifee (1,180 for 100 percent), Bakersfield (1,074 for 89.4 percent), and Fresno (963 for 65.8 percent). Accessory Dwelling Units (ADUs) are included in the single family category of housing and comprised 19.7 percent of the state’s new housing, adding 22,802 units.
