Only seven countries in the world allow gay marriages: Canada, Spain, South Africa, Sweden, Norway, the Netherlands and Belgium. U.S. states that permit same-sex marriage are Iowa, Massachusetts, Vermont, Connecticut and New Hampshire. Argentina's capital established its gay-friendly reputation in 2002 by becoming the first Latin American city to legalize same-sex civil unions. Four other Argentine cities later did the same, and such unions also now are recognized in Mexico City and some Mexican and Brazilian states. Uruguay alone has legalized civil unions nationwide.
