Unfortunately the proportion of people with that level of math skill is probably much lower than you think.
A study done in the UK a decade ago showed that "22 per cent of 16- to 19-year-olds are functionally innumerate" [1].
By "functionally innumerate" they probably mean "unable to manage daily living and employment tasks that require math skills beyond a basic level". (I've paraphrased the Wikipedia entry for "functionally illiterate" here.)
It's just a wild guess but this statistic probably means that only a small percentage of people can do maths to a high school level. So what proportion of people have the skills to write even the simplest useful computer programs?
