IQ Percentiles

The table uses percentiles based of 16 SD (Stanford–Binet scale) data.

There's 7,360,438,325 people in the world...American population is at 321,531,340...

Note: the results are not 100% precise. Not every human has taken an IQ test. Also, results are occasionally an understatement of the true brain power capability. For instance, my IQ was officially tested at 126, but the psychologist does not doubt it's higher, as I was displaying signs of anxiety (but really, I was 4 years old). There can also be psychologist errors, and as such, a "genius" tested at an IQ of 145 could really only have an IQ of 108.
