  Evaluating change in ranked term importance in a growing corpus is a powerful
tool for understanding changes in vocabulary usage. In this paper, we analyze a
corpus of free-response answers where 33,993 LGBTQ Generation Z respondents
from age 13 to 24 in the United States are asked to self-describe their sexual
orientation. We observe that certain labels, such as bisexual, pansexual, and
lesbian, remain equally important across age groups. The importance of other
labels, such as homosexual, demisexual, and omnisexual, evolve across age
groups. Although Generation Z is often stereotyped as homogenous, we observe
noticeably different label usage when self-describing sexual orientation within
it. We urge that interested parties must routinely survey the most important
sexual orientation labels to their target audience and refresh their materials
(such as demographic surveys) to reflect the constantly evolving LGBTQ
community and create an inclusive environment.
