This paper shows the associations between intellectual and physical disabilities. The lack of data concerning the individuals with disabilities population has motivated us to research further upon this topic. The topic deals with people who have physical disabilities and people who have intellectual disabilities in specific states in the U.S. Data about individuals grappling with both physical and intellectual disabilities within California, Texas, and Pennsylvania, spanning the years from 1980 to 2018, was assembled. R-squared values, indicative of the strength of the relationship between occurrences of physical disabilities and intellectual disabilities in these states, were employed to uncover these interconnections. The R-squared values consistently point to a pronounced correlation between these two categories of disabilities. These discoveries imply that individuals with physical disabilities have a heightened likelihood of experiencing intellectual disabilities, and conversely. This study and its associated results serve as a valuable resource for numerous institutions engaged with the people with disabilities community. Furthermore, it equips them with a potent tool for enhanced comprehension of their needs, facilitating the development of more effective and successful contributions.
