 "Jus soli" is the predominant rule in the Americas, but it is rare elsewhere.Since the Twenty-seventh Amendment of the Constitution of Ireland was enacted in 2004, no European country grants citizenship based on unconditional or near-unconditional "jus soli".Almost all states in Europe, Asia, Africa and Oceania grant citizenship at birth based upon the principle of "jus sanguinis" ("right of blood"), in which citizenship is inherited through parents rather than birthplace, or a restricted version of "jus soli" in which citizenship by birthplace is automatic only for the children of certain immigrants.
