Insurance rates, to some extent, are based on group generalizations such as marital status, age and sex. Statistics on these groups allow insurance companies to classify you either as a high or low risk client. The higher the risk, the higher the rate―or vice versa.

Under this criteria, males from 16 to 25 years old are considered a higher risk than females of the same ages. This isn't gender-bias, but a fact. Statistics, culled from many years, prove younger males drive more than younger females and take more chances when behind the wheel. Consequently, this group of males usually faces higher premiums.

Eventually, rates even out as you get older, although some carriers will offer women lower premiums regardless of age. This, again, is based on fact. Statistics show that men receive more speeding tickets than women and, on average, drive more miles.

Remember: Every carrier follows a different equation when establishing quotes. This is especially true with gender-based statistics. So if you think your gender-grouping might affect your insurance rates, it's in your best interest to shop around and compare.
