I take a lot of surveys for side cash (especially around the holidays) and Im seeing it more and more. Almost all of them have female, male, and other but too many are going even more in depth. Some have the typical with transgender added as an option and for other: write in. I always chuckle at that though because you know they just pick whatever they want and not the transgender option. So many important surveys probably really skewed on demograph. Some just leave gender as a write in and I always make sure to put female instead of woman.
