Research suggests that children begin to develop a sense of gender identity around the age of two or three, when they start to understand and use gender labels (e.g. "boy" or "girl") and demonstrate gender-typical preferences and behaviors. While biological sex is determined at birth, gender identity is a social construct and is influenced by a variety of factors, including societal norms and expectations, family and peer relationships, and individual temperament and personality. Research suggests that by the second or third year of life, children begin to understand and label gender appropriately.
