The States and the Differing Impetus for Divergent Paths on Same-Sex Marriage, 1990–2001

Using a regression model of pooled time series data from the 50 states in the United States in the period 1990 to 2001, we look at the political, demographic, and social movement factors that provide the impetus for the enactment of state laws that proscribe the celebration of marriages involving lesbian and gay couples. In doing so, we consider the validity of existing indicators that have been previously associated with the introduction of policies concerning sexual orientation at the state and local level, as well as introduce new factors that might apply uniquely to the area of same-sex marriage laws.
