Wikipedia:Articles for deletion/List of official languages by GDP per capita
It's a simple matter of mathematics, rather than synthesis — take the GDPs for the countries that have X as their official language, combine them, and you have your total.  Such simple mathematics are permitted by the |synthesis policy.  However, this is definitely not the sort of information that belongs on Wikipedia; it's trivia and not at all encyclopedic
