Assuming that 5% of the population is not-heterosexual, we get 14 million out of the 281 million people living in the United States. That's a very rough estimate, but it works. (The 281 is taken from the last census, the 5% are non-heterosexual is not.)

the original ratio was suppose to be 1 for 30,000 people, however over time that has not been enforced. I'm unsure where and why at this point, but I do know it is not in line with the requirements of the Constitution.

I haven't been able to find any exact numbers, but since you asked for fraction, it's about 1/3 or about 2 billion people.

The population of the United States is hovering around 250-300 million people. \n\nAs for the population of the whole of Europe, I have no idea.

I don't know.  But in the USA it should be close to 800,000 people.  Mind boggling huh?

You can find that sort of information on a government demographics webpage.  Just google it.

There doesn't seem to be any place on the net with this particular answer.  I've tried several search engines and nothing points to it.  \n\nHowever I can tell you that the population of the world as of this hour (17:49 GMT (EST+5) Jan 02, 2006) stands at 6,488,933,852. (1st link below).  \n\nAlso the census bureau has an area in which you can e-mail a question to them.  You may want to try that.  It is the 2nd link below.\n\nGood Luck!\n\n:)\nPeace
