N.B. Boys are under-presented in police samples.

My comments

To understand the enormity of the of the problem of sexual abuse of boys in the world, consider the following:

a)If the rate is 5 to 10% of all males and the present world population is 6.5 billion, of which 3.25 billion are boys, this means 325 to 650 million males of the present world population have been sexually abused as boys.
b)If the rate is 5 to 10% in Australia and the number of males in Australia is about 10 million, this means 500,000 to 1 million Australian males have been sexually abused as boys by adults or much older children.
c)If the rate is 5 to 10% and the U.S. population is 296 million, of which half are boys, this means about 14.8 to 29.6 million males in the present American population have been sexually abused as boys.
d)If the rate is 5 to 10% and the European Union population is 457 million, of which half are boys, this means about 22.85 to 45.7 million males in the present European Union countries have been sexually abused as boys.

The above figures are so large, they are hard even to grasp or imagine. But they are no fantasy. This is one of the greatest catastrophes in human history. The real sex abuse figure of boys may be even higher than 5 to 10% in some or many countries.

Future additions to this study

This study is developing and ongoing. There will be many additions made to it in future.
