Final answer:
Projected job growth is higher for positions requiring higher education, with a 17 percent growth for jobs requiring a bachelor's degree, suggesting a trend toward a greater need for college degrees in California by 2030.
Step-by-step explanation:
While the exact percentage of jobs in California that will require a college degree by 2030 is not provided, we can infer a trend from the provided information. Job growth is projected to be higher for those with more education. For example, jobs requiring a bachelor's degree are expected to grow by 17 percent. This may indicate a greater percentage of jobs in the future necessitating a college degree, which could exceed the current percentage of individuals holding such degrees, considering the fact that only 33.6% of Americans between the ages of 25-65 had a bachelor's degree as of 2014.
