A referendum on continued membership of the Federation of the West Indies was held in Jamaica on 19 September 1961.[1] Voters were asked "Should Jamaica remain in the Federation of the West Indies?" The result was 54.1% voting "no", resulting in the country leaving the federation and its dissolution in 1962. Voter turnout was 61.5%.[2]
