Dr. Gary Gates, one of the nation’s most renowned experts on the geography and demography of the LGBT population and coauthor of The Gay & Lesbian Atlas, joins the podcast to explain the significance of these measures and to discuss the changes Gallup has seen over hundreds of thousands of interviews since 2012.
