Is there any way to know approximately what % of men are a danger to women?

Edited to add title should be unknown men.

I’m in my mid-40s, and fortunate to have never been assaulted, but I have had some close calls when younger. As I got older I never put myself in situations where I would be in a remote area, for fear of men (based on the close calls). I hate living like that to be honest. I wonder if I’m being sensible or overly fearful.

No, I don’t think there is such a way.

Here are some stats about rapes/assaults in public areas but of course it is only reported ones, doesn’t include lower level but threatening behaviour like blocking your path or cat calling etc.

The year ending March 2020 Crime Survey for England and Wales (CSEW) estimated that 1.6 million adults aged 16 to 74 years had experienced sexual assault by rape or penetration (including attempts) since the age of 16 years. Analysis of the nature of these assaults uses CSEW data from the years ending March 2017 and March 2020 combined and is limited to adults aged 16 to 59 years.1
Of victims who experienced sexual assault by rape or penetration (including attempts) since the age of 16 years:

• almost half (49%) had been a victim more than once
• fewer than one in six (16%) reported the assault to the police and of those that told someone but not the police, 40% stated embarrassment as a reason, 38% did not think the police could help, and 34% thought it would be humiliating
• more than four in ten (44%) were victimised by their partner or ex-partner
• nearly one in ten (9%) were victimised on the street, in a car park, park, or another open public space compared with over one-third (37%) in their own home

Following. Having therapy and unfortunately it’s bringing back some memories of being forced into situations I didn’t want / like or enjoy.

Now I am older I have just withdrawn. I don’t even cycle or walk alone. Used to love running but don’t run alone anymore.

You can look up statistics for people who've been convicted of things I think. Then work out the percentage of the population that represents.
But who knows how many haven't done something yet but would. Or have done stuff and got away with it.
It's best to assume that the vast majority of people are not harmful to others and are just trying to get on with their own quiet existence.

I'd say 100%.

Does it matter? Even if it's only a small percentage, those few can be prolific. So your chances of being assaulted will be higher than the percentage of men who are offenders. I'm not sure knowing a percentage helps a great deal with your risk assessment.

No I don't think so!

I'm 20 and I find it best to be "fearful" of them all while carrying a small hairspray at easy reach.

Sorry if that sounds confrontational. (Un)fortunately I'm blonde (usually!) and blue-eyed and I seem to attract creeps.

I don’t you can tell. As @BobbyBiscuits says, you don’t know if someone will offend in the future, or did a drunken grope when seventeen, but never touched anyone since. Potentially, a hundred percent of men could cause problems, but realistically I like to think that most people are decent.
