Final answer:
The statement is false as non-Hispanic Whites make up about 42% of California's population, not more than three-quarters as suggested in the question.
Step-by-step explanation:
False is the correct answer to the statement 'Despite immigration of various groups, Whites still comprise more than three-quarters of California’s population.' According to recent demographic data, the percentage of non-Hispanic Whites in California is around 42 percent, which is significantly less than three-quarters. With a Hispanic population that represents 37 percent of Californians and other minority groups also accounting for substantial proportions, the demographic landscape is much more diverse. Furthermore, Asian Americans have been reported to be the fastest-growing ethnic group in the state, with significant increases evident from the U.S. census data.
