The source of population estimates needed to calculate various TB indicators was the 2015 revision of the World Population Prospects, which is produced by the United Nations Population Division (UNPD). (UNPD, \url{http://esa.un.org/unpd/wpp/}).  The UNPD estimates sometimes differ from those made by countries.
