The Scottish Independence Referendum Bill, setting out the arrangements for this referendum, was passed by the Scottish Parliament in November 2013, following an agreement between the Scottish and the United Kingdom governments, and was enacted as the Scottish Independence Referendum Act 2013. To pass, the independence proposal required a simple majority. With some exceptions, all European Union (EU) or Commonwealth citizens resident in Scotland aged 16 or over could vote, a total of almost 4.3 million people.
