It varies across age groups and among different racial or ethnic populations due to genetic, cultural, and environmental factors.

1. Age and Body Composition: Across the lifespan, body composition changes. Babies have a higher proportion of body fat compared to older children and adults. As people age, there tends to be a decrease in muscle mass and bone density while the percentage of body fat may increase.
2. Racial and Ethnic Variations: Different racial and ethnic groups often exhibit variations in body composition. For example, certain populations might have different distributions of fat and muscle. For instance, some studies suggest that individuals of Asian descent might have a higher percentage of body fat at a lower BMI compared to individuals of European descent.

These variations can have implications for health, fitness, and disease risk assessment. Understanding these differences helps healthcare providers in tailoring interventions and health recommendations that are more specific and effective for diverse populations.
