Number of California Bills by Code – 2025 Edition

California’s 29 Codes, beginning with the Business & Professions Code and ending with the Welfare & Institutions Code, contain over 156,000 statutes. Each year, more statutes are being considered through legislation. So, how many bills introduced in 2025 affect these 29 Codes?

In the following chart, I look at the number of bills adding, amending, or repealing sections of California’s 29 Codes during the 2025 Session, along with the 2023-24 Session statistics for comparison purposes. The following chart contains those numbers:

Code	2025	2023 – 24
Business & Professions	333	632
Civil	290	495
Civil Procedure	179	310
Commercial	13	22
Corporations	51	109
Education	322	644
Elections	78	142
Evidence	60	116
Family	62	187
Financial	46	69
Fish & Game	68	127
Food & Agricultural	55	125

Streets & Highways	64	141
Unemployment Insurance	59	109
Vehicle	135	318
Water	90	184
Welfare & Institutions	331	671

Most interesting to me is the relative consistency each Session with the number of bills affecting the same Code, certainly over the past decade that I have been tracking this data. In other words, during the last decade, roughly the same number of bills each Session affect an individual Code. Also note how the 2025 Session numbers, the first year of the 2-year Session, is roughly half of the prior 2-year Session numbers.
