Geographic region: These data are available by state and county.

Data on the number of children in the early intervention are available by a number of different counts. This most accurately represents the number of children who are actually receiving services. The data are point-in-time data for a date in October of the fiscal year. For additional information about the early intervention program, see the IDHS Early Intervention webpage.

For privacy reasons, IDHS data on the number of children served are not reported for areas in which there were fewer than 10 children served.

Because data are not reported for all counties, the sum of counties does not equal the total number of children served for the state as a whole.
