how many kids are there in the world
Not enough! Many countries are having negative population growth, which means in a few decades they won't have enough people working to pay the taxes that fund their governments.
A lot less since zombies starting eating people.
there are roughly 2 and a half billion people under the age of 18
http://en.wikipedia.org/wiki/World_population#Global_demographicsIf the global population is estimated to be 26.3% under the age of 15, and the total population is estimated to be 7.076 BILLION people, then...1.861 BILLION people are under the age of 15
