In its ongoing series examining the economic activity generated by gay marriages, the Williams Institute recently released several analyses for states that have yet to make same-sex marriage legal. The studies estimate the number of weddings in three years after the legalization of gay marriage based on Census data and marriage rates among gays in Massachusetts (the first state to allow gay weddings). The revenue is an estimate based on average costs associated with those weddings and how much out-of-town guests would spend in the local economy.
The map below shows estimates for several states that the Institute has recently applied its formula to as well as analyses for states where gay marriage has only recently become legal, including Illinois. Click on a state for more details:
