Final answer:
An increase in people with gender dysphoria can be attributed to increased awareness, environmental factors, and genetic predisposition. Greater societal knowledge, scientific research into genetics and hormones, as well as social and cultural pressures all play roles in how gender identity is experienced and expressed.
Step-by-step explanation:
The reasons for an increase in people with gender dysphoria are multifaceted and can include increased awareness and acceptance, environmental factors, and genetic predisposition. Over time, society has become more knowledgeable about gender identity issues, leading to a greater recognition and diagnosis of gender dysphoria. Additionally, scientific research suggests that genetic and prenatal hormone influences may play a role in a person's gender identity, but these are complex and not yet fully understood. Childhood and adulthood experiences, alongside societal pressures and acceptance levels, also contribute to how individuals perceive and express their gender. It is the combination of these biological, social, and cultural factors that most experts agree upon as influencing gender identity.
