If we define "kids" to be humans aged 0-14, then from
http://www.un.org/esa/population/publications/wpp2006/FS_ageing.pdf
we find that there are currently (2011) approximately 1.9 billion such humans based on a 2005 United Nations data projection.
There is no accurate number for how many kids live by themselves. In most states, kids under the age of 17 or 18 cannot live by themselves and has to live with an adult.
400,000
eleven
Too many to count
6 billion people live on Earth.
The book "The Last Kids on Earth" by Max Brallier contains approximately 34,000 words.
Many, as all life on Earth comes from Gaia for she is the personification of the Earth itself.
