This report is the 34th edition of the annual National Deaf-Blind Child Count, the first and longest running count of children who are deaf-blind in the world. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on Deaf-Blindness (NCDB), its predecessors, and state deaf-blind projects throughout the country, including multi-state projects and projects funded in the Pacific Trust territories, the Virgin Islands, and Puerto Rico. Each year, the state deaf-blind projects collect data on children in their states (birth through 21) who are deaf-blind and submit it to NCDB. Data is collected using a timeline aligned with one the U.S. Department of Education's Office of Special Education Programs (OSEP) uses to collect data on children (birth through 21) receiving special education services. For the OSEP data collection, each state designates a date between October 1st and December 1st on which they capture a point-in-time "snap shot" of children who are eligible for IDEA Part C or Part B services (U.S. Department of Education, 2020). Similarly, state deaf-blind projects use a point-in-time "snap shot" date of December 1st to capture the number of children eligible for their state deaf-blind project services. NCDB provides technical assistance to the projects to help them conduct their counts and compiles the data into this national report. [For the 2018 report, see ED608548.]
