The other day we had a society meeting. That was over pretty quickly because we’re a very organised bunch but eventually we got around to a different topic:
How many people in the UK were having sex at 18:03 Sunday 29th September?
(Please keep in mind that this is based on HEAVILY estimated data! You’re quite welcome to point out where our estimates were wrong but they were just estimates based on our collective knowledge.)
- The population of the UK is 62 million. Let’s say 60 million for the sake of maths
- Discount 50% of the population (>65 years/
- Account for the fact that it’s 18:00 on a Sunday = the only people likely to be having sex are those in relationships
- On average people in established relationships have sex three times a week so they have a 3/7 chance of having sex today
- 3/7 of 30 million = 3.4 million
- 24 hours in a day – 7 hours for sleep = 17 hours to potentially have sex
- 3.4 million / 17 hours = 100, 000 people having sex each hour
So. After that we saw that someone had already asked this question. The answer is that on any random day on a random hour sex happens an average 5.5 million times in a population of 6.7 billion (we’ve done enough maths for today… We’ll pretend that’s the current population….) We already set the population of the UK at 62 million which means if we round the numbers it means we were right! In the UK 100,000 people are having sex each hour!
So yeah, considering how much leeway we took with the numbers, we got pretty close!
