The care and fair treatment of individuals diagnosed with intellectual and developmental disabilities (IDD) is a globally evolving concern. Within the United States, federal and state governments along with private sector organizations are tackling issues relating to housing, victimization, lack of financial resources, healthcare, loneliness, and quality of life of individuals diagnosed with IDD. Central to the issue of improved outcomes for the group are the associated costs. Most individuals in the U.S. diagnosed with IDD do not have income or assets sufficient to cover costs associated with their care. Therefore, federal and state governments have assumed the greatest share of associated costs. The purpose of this study is to determine whether relationships exist between state and federal funding allocations and outcomes achieved by individuals diagnosed with IDD. This study employs One-Way Analysis of Variance and Linear Regression methods to evaluate per person spending and quality of life outcomes achieved by individuals diagnosed with IDD residing in as many as 41 states and municipalities during years 2011, 2013 and 2015 using publicly available data. The study found that in all but one instance the amount of money allocated to provide care for individuals diagnosed with IDD was not significantly correlated to quality-of-life outcomes achieved by these individuals.
