How this is measured
Most figures are CLDR's estimates of speakers. CLDR lists only each country's larger languages, so where it has no figure a national census or official survey fills in, and the Figure column says which and what it counts. A home-language figure is a floor: more people can speak the language than use it at home.
States where it is the first language
States whose first language is this one, largest population first.
