2.0% of 50% of 20,000 = 200 (+/- 4) men {196-204 men}
1.4% of 50% of 20,000 = 140 (+/- 4) women {136-144 women}
Population of Australia (rough): 20.8 * 10^6
2.0% of 50% of Austraila = 21(0,000) men
1.4% of 50% of Austalia = 15(0,000) women
Population of Earth: 6.6 billion (rough): 6.6 *10^9
2.0% of 50% of Earth = 66 million
1.4% of 50% of Earth = 46 million
Assuming:
-2.0% of men on Earth are into BDSM-esque activities
-1.4% of women on Earth are into BDSM-esque activities
-The population is 50% male, 50% female (false assumption towards the earlier and later years. Approximate.)
-The Earth's population to be about 6.6 billion.
-All people are on Earth. ("People" refers to Earthlings!)
Then..
(0.0195+0.0135)/2 * 6.55 * 10^9 to (0.0204999999999 + 0.01449999999999)/2 * 6.64999999999 * 10^9 people are into BDSM-esque activities.
108,075,000 to 116,375,000 people are into BDSM-esque activites.
(So, about 112 million people give or take 4 million, roughly.)
Yeah.. I really should be doing my Engineering homework.. but BDSM is more interesting. =/
I would like to note something from Sociology 101:
"Poor people are more likely to be economically liberal and socially conservative."
"Rich people are more likely to be econonmically conversative and socially liberal."
With this in mind, Australia, being a more developed nation, is likely to have a higher ratio of "socially liberal" individuals- the demographic that would support BDSM more readily. Taking this source of error, and no others, into account, one would have to say that the 112 million figure is probably high. However, this is not considering more dynamic social issues and assumes that the test was accurate for the Austrilian population after a sample size of twenty thousand is assumed to be honest.
The majority of countries in the world number fewer than 112 million in population.. such as, Austalia, above, having only 20.8 million (18.6% of 112 million).
Possible ways to increase accuracy:
-Find other polls.
-Better define "BDSM-esque activities".
-Take into consideration different types of populations and their appropriate weights.
-Better estimate global population.
-Acquire credible means of dividing the population based on gender, or more accurate gender-based population figures.
Edit: Math mistake.
