Gender Differences in Personality across the Ten Aspects of the Big Five
Of the 2643 participants, 69% were from "a large Canadian metropolitan area", 18% were from Eugene-Springfield, Oregon, United States, and the remaining 13% were recruited online with Amazon's Mechanical Turk service. By gender, 66% were female and 34% were mail. By racial/ethnic identity, 40% were White, 28% Asian, <1% others, and the rest unstated (about 30%).
The study used DeYoung's two-way split of each of the five factors. Here is Table 2 from their results:

The d is a statistical measure of (female) - (male) difference.
The two sexes show some differences, but not great ones, and they have a *lot* of overlap. This study's results are consistent with previous studies' results about gender differences for the five factors.
