N.B. The figures include both first and second-language speakers.

The countries are:

Australia (272,000 speakers), Brazil (50,000 speakers), Eritrea (no figures given), France (829,000 speakers), Malta (234,430 speakers), Monaco (7110 speakers), Romania (1,412,950 speakers) and Somalia (4000 speakers).

The biggest surprise is how Australia and Brazil are listed but not the USA, Uruguay or Argentina.
