The percentage of the population that is transgender varies depending on the source and the age group being considered. Here are some estimates:

• According to a study published by the Williams Institute in 2022, approximately 1.4% of the U.S. population identifies as transgender.
• The same study found that 1.6 million people ages 13 years and up identify as transgender in the United States.
• Another study published by the Williams Institute in 2017 estimated that 0.6% of U.S. adults are transgender.
• A survey conducted by Pew Research Center in 2022 found that 1.6% of U.S. adults are transgender or nonbinary.
• The US Census Bureau Household Pulse Survey, which started collecting information on gender identity in July 2021, found that about 1.03% of the nation’s adult population identifies as transgender.

Its worth noting that the estimates above are based on different methodologies and may not be directly comparable. Additionally, the percentage of the population that is transgender may be higher among certain age groups. For example, the Pew Research Center survey found that 5.1% of adults younger than 30 are trans or nonbinary.
