Delaware became the 11th state to join the forces of marriage equality on Tuesday. With this momentous week for the equal rights movement, we decided to begin a Marriage Equality Census, keeping an estimated count of the number of self-identified LGBT citizens that can legally get married in their home state. See the number in the graphic above.

Here’s how we got to this grand number: We pulled 2012 U.S. Census Bureau data of the population for each state that has full marriage equality (not civil unions). Then we combined it with information gathered by a 2012 Gallup poll in conjunction with the Williams Institute at UCLA, which identified the percent of self-identified LGBT people in each of those states. See the table below for the numbers.

Which state will be next? —Scott McPherson
