IQ is not rising; literacy rates are falling in the developed world. As an example, fewer people are literate in Massachusetts now than when it was founded.
I'm also sensing we may be having some trouble in the math department.
I am suspicious of the literacy rates in [0] and [1]. It seems that someone who immigrates from a foreign country would be considered illiterate if they did not speak English, but had high proficiency in reading and writing in their native language. Not knowing one specific language is very different from being generally uneducated.
