The nationally-accepted prevalence rate estimate used by the Administration on Developmental Disabilities for estimating the state rate is 1.8 percent of the general population. By applying the 1.8 percent prevalence rate to Mississippi's 2025 population projections, the results equal 56,072 individuals who may have a developmental disability. The intellectual and/or developmental disability bed need determinations can be found in Chapter 2 of this Plan.
