Yes, women take longer, yes, women go more often. Thus for an equal number of men and women at a venue there should be 2 female stations for one male.
The British Toilet Association is campaigning – too quietly, perhaps – for public facilities to uphold a 2:1 ratio of women\’s to men\’s loos. They haven\’t triumphed yet.
However, there\’s something at the back of my mind that I recall from the dim and distant past that I think I erad upon the intertubes. Something I couldn\’t find when I wrote this.
At the back of my mind there is something from queueing theory: queues do not grow as a direct multiple of the time taken, they obey a square law. That is, the wait to use something will grow as the square of the difference between usage times, not a simple multiple. Which means that if women take twice as long as men then to equalize waiting times we need to have four times (2 times 2) as many women’s as men’s. Or maybe it’s an inverse square law meaning we need 1 plus the square root of two times as many…..does anyone actually know?
