Whether same-sex couples should be allowed to marry has been and remains the topic of debate worldwide. 32 countries and four jurisdictions worldwide have passed constitutional amendments that explicitly prohibit the legal recognition of same-sex marriage and sometimes other forms of legal unions as well. Sixteen countries and 34 jurisdictions worldwide have authorized civil unions or unregistered cohabitation for same-sex couples as an alternative to marriage. The legal name of those unions as well as the number of rights that they provide can vary greatly.
