Here are the Worlda Language maps, if anyone's curious:
No idea how updated are they compared to the Next-gen Worlda (they look of a different size altogether) but could be a very useful source if updated. They're not free from weird things though and they often overrepresent minority languages. For example in Argentina, the proportion of Spanish speakers in Corrientes is larger than Guaraní speakers, though many in rural areas do have it as a second language. On the other hand, some native langauges are underrepresented, too, and let's not even get in the 'Bantu' catchall mess in Africa.
Still, a useful source.
