Note: To calculate the percent of people served in a state under IDEA in a specific age group, divide the number served in the age group by the total number served by IDEA in the state and multiply the result by 100. Example: Calculate the percent of people in Montana age 3-5 years served by IDEA. This calculation would be: 1,614/19,039=.0848 and .0848x100=8.48%
