As of the end of 2010, the Boy Scouting division of the Boy Scouts of America had 898,186 boys.
world population is 6680 million. there are 105 boys born per 100 girls. 6680/2 = 3340. 1.05*3340 = 3507. 3507 million boys.
3.2 is good, but we don't know if there will be more girls than boys cause we can't predict the future. if there are more girls then human population might extinct by 2100 also the adding pollution...
depends, what are we talking? world statistics, classrooms, websites?
