I don't understand why you're including the sub 30 second 200m in this. No really, it makes absolutely not sense, because it is completely (obviously) redundant.
So assuming you are just saying 60 seconds in the 400, lets look at it like this.
Maybe you can get 1-2 girls, on average, in a moderate sized HS, that can run sub 60. In college, probably 40% of 100m-3000m females can break it. There might be a few very talented soccer players that can break 60. I think that would be about it, with a very tiny amount of other athletes sprinkled in. All in all, the number of women who can break 60 is likely under 40,000 people, maybe as low as 20,000.
So women: ~35,000 people +/- 10,000
With men, around 1/3 of a HS track team can break 60 (maybe less at some High Schools). Still in HS, there are definitely some soccer, football, and basketball players, along with a few athletes sprinkled around other sports, that can break 60 as well. Every single college track and soccer athlete can break 60 without any issue (and probably 90% of collegiate jumpers and pole vaulters), and many basketball, football, and even some hockey and baseball players as well. Maybe 50% of all professional athletes can break 60, regardless of their sport. Then there are likely 5-10% of people who play sports for fun, like play pick-up games of basketball, or are in a small soccer league, etc, that can break 60. I lived in South America for a couple years, and maybe 30% of 15-28 year olds were somewhat fit from all the soccer they played—maybe 10-15% of them could break 60 seconds in the 400. Of the non-athletes, who are aged 16-35, who are somewhat slim and go to a gym or other fitness program—perhaps 5-10% of all them—can break 60.
I would imagine that number is somewhere under 50 million, which would be >0.7% of the total population. I think that's accurate, somewhere under 1% of all the existing people on the planet are able to run sub 60 seconds in a 400. I mean just go walk anywhere and select the first 100 people you see—likely only zero to one of them can break 60 seconds. Cross culturally.
