Findings from the Maryland Autism and Developmental Disabilities Monitoring (MD-ADDM) program help us understand more about the number of children with autism spectrum disorder (ASD), the characteristics of those children, and the age at which they are first evaluated and diagnosed.

1 in 43

Or 2.3% of 8-year-old children were identified with ASD in 2020

1 in 43Or 2.3% of 8-year-old children were identified with ASD in 2020

This percentage is lower than the overall percentage identified with ASD (2.8%) in all communities tracked by the CDC.

About 1 in 59

Or 1.7% of 4-year-old children were identified with ASD in 2020.

About 1 in 59 or 1.7% of 4-year-old children were identified with ASD in 2020.

This percentage is lower than the overall percentage identified with ASD (2.2%) in all communities tracked by the CDC.

Among 8 year-olds, Black and Asian/Pacific Islander (A/PI) children were twice as likely to be identified with ASD as Hispanic and White children.

Among 8 year-olds, Black and Asian/Pacific Islander (A/PI) children were twice as likely to be identified with  ASD as Hispanic and White children.

Values indicate prevalence per 1000.

Among 4-year-olds, Black children were 2.3 times as likely and Asian/Pacific Islander (A/PI) children were 1.9 times as likely to be identified with ASD as White children.

Among 4-year-olds, Black children were 2.3 times as likely and Asian/Pacific Islander (A/PI) children were 1.9 times as likely to be identified with ASD as White children.

Values indicate prevalence per 1000. There were no significant differences in identification between Hispanic children and White children.

47% of 8-year-old children

About 83% of 4-year-old children identified with ASD received a comprehensive developmental evaluation by 3 years of age.

What are the key take-away messages from MADDSP?

  • The prevalence of ASD in MD-ADDM continues to increase.
  • Following the onset of COVID-19 in March 2020, there was a reduction in the number of evaluations in all ADDM communities, including MD-ADDM.
  • Black and Asian/Pacific Islander children are more likely to be identified with ASD than White children in MD-ADDM.
  • Most 4-year-old and 8-year-old children identified with ASD in MD-ADDM had a comprehensive evaluation by age 3 years, but more 4-year-old children had one compared with 8-year-olds.

How can this information be useful?

MD-ADDM’s latest findings can be used to

  • Promote early identification of ASD.
  • Identify and plan for the service needs of individuals with ASD.
  • Improve collaborations between health providers, educators, researchers, and the children with ASD and their families.
  • Inform policies promoting improved health and education outcomes.
  • Guide future ASD research.

How and where was this information collected?

MD-ADDM uses a record review method. Specifically, this information is based on the analysis of data collected from the health and special education records of children who were 4 and 8 years-old and living in five counties in Maryland in 2020.

Tracking areas: Baltimore, Carroll, Cecil, Harford, and Howard counties

8-year-old children in tracking area: 21,278

  • 51% White
  • 24% Black
  • 9% Hispanic
  • 10% Asian or Pacific Islander
  • <1% American Indian or Alaska Native
  • 6% Multiracial

4-year-old children in tracking area: 20,745

  • 51% White
  • 23% Black
  • 10% Hispanic
  • 9% Asian or Pacific Islander
  • <1% American Indian or Alaska Native
  • 6% Multiracial

What else does MADDSP do besides provide estimates of ASD
among 8-year-old children?

MD-ADDM collaborates with the Maryland Department of Health, the Maryland State Department of Education, the Kennedy Krieger Institute, and local school districts, to track the number and characteristics of 4-year-old and 8-year-old children with ASD. MD-ADDM offers presentations for partners, state and local agencies, partnering institutes, parent groups, and the ADDM Network. MD-ADDM also participates in and organizes annual autism awareness month events in the community.

“There was a major impact of COVID-19 school closures on timely evaluations and early intervention and special education services. Our regular resources were not enough to address that increase in needs. The ADDM prevalence data are timely for planning and making budgetary requests for staffing to inclusively meet these needs.”
