Men's vs. Women's Car Insurance Premiums
Quantifying the Sex-Based Pricing Gap in Car Insurance
Men may like to think that they're the best drivers on the road, but it's common knowledge in the insurance industry that they tend to take more risks behind the wheel than women and end up getting into more accidents as a result. What does that mean for their auto insurance bills? Well, demographics that cost insurers more to cover tend to have higher policy prices, so men usually pay more than women for coverage.
We wanted to quantify the auto insurance pricing gap between men and women, so we looked at almost 5,000 quotes provided by insurance regulatory agencies in seven states (Texas, Iowa, Ohio, Kansas, California, Oklahoma, and West Virginia) to see which sex gets charged more for the same coverage, how often it happens, and how big the average price difference is.
The data showed women were quoted less for coverage most of the time, and the size of the price breaks they got were often sizeable.
Men Were Quoted Higher Prices 62 Percent of the Time
The analysis showed that insurers quoted men a higher rate 62 percent of the time. And when men were quoted more for coverage, they generally weren't charged just a little more. They were charged a lot more. The average price difference between a male and female quote was $471 a year. That amounts to a 23 percent average surcharge just for being male.
These differences weren't the result of the male drivers' having worse driving records, higher annual mileages, worse credit scores, or any other negative factors that could account for drastic differences from their female counterparts. All of the quote pairs were made up of two drivers with the exact same driver profiles with the only difference being the sex of the driver. In each male/female comparison, both drivers were the same age, had the same car, lived in the same area, had the same driving history, put in the same annual mileage, and were buying the same coverages.
But men weren't always quoted higher prices for coverage. About 11 percent of the time, the insurer actually quoted the female driver a higher rate. However, when the female was quoted more, the price difference was much smaller than when men saw the higher quote. In the cases where women were quoted a higher price, the average difference was only $98 a year - an average surcharge of 5 percent.
In a little more than a quarter of the quote pairs, the insurer employed unisex pricing where the male and female were quoted the exact same price. This happened 27 percent of the time.
Sex-Based Pricing Trends Depend on Age of Drivers
The results were far from being uniform across all age groups.
The data indicate that sex-based price differences are most prominent when drivers are younger, fade between the ages of 25 and 65, and come back into play for drivers 65 and over.
Something else to note is the size of the average difference for each of these age categories. For the under-25 crowd, the average gender-based price gap was $676 a year. For the 25-65 group, it was only $32.
First, let's look at the youngest age group. The comparison of quotes for drivers 25 and under showed that young men are almost always quoted more than young women for coverage. Men under 25 were asked to pay more than women of the same age almost 96 percent of the time. Prices for both young men and young women were the same under 1 percent of the time, and young women were asked to pay more about 3.5 percent of the time.
Now contrast that with the quotes for drivers between the ages of 25 and 65. When comparing quotes for this age group, insurers most often quoted men and women the same price for coverage; this happened 44 percent of the time. Insurers quoted men in this age group a higher price 39 percent of the time, and they quoted women higher prices than men 17 percent of the time.
For the 65-and-older crowd, males' prices went back up a little. They saw higher prices than women 55 percent of the time. Women 65 and over saw higher prices 11 percent of the time, and sex wasn't a factor in 34 percent of the cases for this age group.
Why the Differences in Pricing?
While men may have decades of male chauvinistic thinking on their side saying that they're the superior sex behind the wheel, national crash statistics appear to tell a different story.
In 2010, for example, men were involved in 1.25 million more crashes than women, according to federal crash data. That's despite the fact that there were significantly more licensed women than men that year.
The average man had a 1-in-19 chance of getting into a police-reported crash in 2010. The average woman, meanwhile, had a 1-in-25.5 chance.
And the numbers look even worse for males when the focus is on fatal crashes. The average man had about a 1-in-3,280 chance of being involved in a crash of that kind. The average woman's chances were 1 in 8,985.
Why do men have higher crash rates?
One factor may be the difference in how often men and women drive. Less time on the road means fewer chances to get into accidents, and women do tend to report putting in fewer miles behind the wheel. In 2009, the average male drove about 1.5 times as much as the average woman, according to the most recent National Household Travel Survey conducted by the Federal Highway Administration.
But men have also been found to take more risks while driving than women.
One study found that men get cited for not wearing a seat belt, driving recklessly, and driving drunk at a rate that's more than three times higher than women. In the 2008 study by Quality Planning, women were also found 27 percent less likely than men to be deemed responsible for an accident.
"This again underscores the finding that women are on average less aggressive and more law-abiding drivers — attributes that also translate to fewer accidents," the company, which helps insurers find flaws in their rating systems, said about the findings.
"And because men are also more likely to violate laws for speeding, passing, and yielding, the resulting accidents caused by men lead to more expensive claims than those caused by women," Quality Planning president Raj Bhat said in a statement about the study.

The Up Side
The good news for men is that, if national accident statistics are an accurate indication, the sex-based pricing gap may be shrinking.
Back in 1988, men's accident involvement rate was 62 percent higher than women's, according to federal crash data. But that gap has been closing pretty consistently ever since. By the year 2000, men's crash rates had fallen to be 49 percent higher than women's. And the most recent data show that men's crash involvement rate is now just about 32 percent higher than women's.
The good news for everyone is that crash rates as a whole have fallen considerably over the past few decades, which means roads are getting safer.
The Ethics of Sex-Based Pricing
As of Dec. 21, 2012, insurers in the European Union will be banned from taking a policyholders' sex into account when determining how much to charge them for coverage. The change was set into motion when the Court of Justice of the European Union ruled in a high-level case that "different premiums for men and women constitute sex discrimination."
In a statement about the ruling, the EU's justice commissioner cited a decades-old U.S. Supreme Court decision that ruled the Civil Rights Act of 1964 prohibited "different treatment of insured persons on the basis of their sex in connection with pension funds." The mention was ironic, considering that most states in the U.S. allow auto insurers to use sex as a factor in determining how much to charge an individual for coverage. But some states have taken measures similar to the EU and have banned sex as a rating factor for auto insurance. They include Montana, Massachusetts, Michigan, North Carolina and Pennsylvania.
According to one industry expert, the U.S. is unlikely to take action similar to the EU on a national level. That's because insurers in the U.S. are usually allowed to use rating factors if they correlate with actual risk posed by the policyholder, even if they're controversial.
