Question

How is the population of the Earth counted and how many of us are there now?

Answer 1

In Canada, the governemnt has s Census (A survey) it gets sent out to every household and you are required to fill it out and return it.(a certain percentage of households get a bigger package with more questions)

This helps in determining population, average income, ages, number of childre, etc..

I don't know what the rest of the world does, but I would guess something similar

Answer 2

The USA & Russian, and of late Chinese space labs has a more accurate way of knowing. They send out probes by means of ultra sonic radio waves from outer space to detect live human beings.This is done by having the mean differential body temperature of a homo sapien and radio resonance of the DNA of a human being. that will get the most accurate count. the last count was 6,742,530,369 with a error margin of 0.025%.

SCARY isn't it.
