Data Scientists in California. BLS OES + DOL OFLC + reader-reported submissions. How this is built →
What the numbers say
The median Data Scientist in California earned $136,800 in 2024, about 18% above the US median of $115,636. The mean came in higher at $155,450, which tells us a group of top earners pulls the average well above what most people in the role actually make.
The spread between the 10th and 90th percentiles runs from $73,390 to $221,080. Top earners in California make roughly three times what the lowest-paid 10th do. That kind of range usually reflects real differences in seniority, specialization, and the industry doing the hiring, not noise in the data.
California's overall cost of living runs about 15% above the national baseline. After adjusting for that, the $21,164 nominal premium over the US median shrinks to something closer to $3,900 in real purchasing terms. The headline number is real; what it buys is closer to the national figure than it first appears.
BLS projects employment for Data Scientists to grow 33.5% between 2024 and 2034, a rate it classifies as much faster than average. California's 36,850 jobs in this occupation represent one of the largest state-level concentrations in the country, concentrated in technology, finance, and health care sectors that have absorbed the bulk of recent hiring.
