Which subgroup represents the largest population of individuals with mental retardation?

The subgroup representing the largest population of individuals with intellectual disability is the mildly retarded group. This classification typically encompasses individuals who have an IQ between 50-70. Mild intellectual disability is often characterized by the ability to learn basic academic skills and functional skills needed for independent living, leading many individuals in this category to integrate into society with varying degrees of support.

The prevalence of mild intellectual disability can be attributed to various factors, including genetic conditions, environmental influences, and developmental conditions that can affect cognitive function. Studies and population assessments consistently show that the majority of individuals with intellectual disabilities fall into this mild category, highlighting the necessity for targeted educational and developmental interventions aimed at promoting independence and enhancing quality of life.

In contrast, the other classifications—severely, moderately, and profoundly retarded—represent smaller segments of the population, typically due to more profound cognitive and developmental challenges that significantly limit intellectual functioning and adaptive behaviors.
