A Snapshot of Autism Spectrum Disorder in New Jersey

Download and print this page [PDF – 257 KB]

Findings from the New Jersey Autism Study (NJAS) help us to understand more about the scope of autism spectrum disorder (ASD) in children, describe the expression of ASD in those children, and identify disparities in the prevalence or detection of ASD.

3 percent is higher than the average percentage identified with ASD in 2014. 1.7 percent in all ADDM sites

Disparities in Identification

Boys were more likely to be identified with ASD than girls.

3.7x more likely among boys vs. girls

No significant difference was found in the percentage of white, black, and Hispanic children with ASD.

Intellectual Disability in New Jersey

New Jersey had intelligence quotient (IQ) data available for 72.1% of children identified with ASD. Of those children, 28% had intellectual disability.

Intellectual disability is defined as an IQ score of 70 or lower.

Frequently Asked Questions

What are the key take-away messages?

  • The percentage of children with ASD increased in New Jersey, from about 2.5 percent in 2012 to about 3 percent, in 2014. Rising numbers of children with ASD need services and support, now, and will require significant resources as they grow into adolescence and adulthood.
  • Boys continue to have a higher ASD prevalence than girls. In 2014, almost 4 percent of boys in the area were identified with ASD, compared to about 1 percent of girls.
  • ASD prevalence in New Jersey did not vary by race or ethnicity in 2014, unlike in 2012, suggesting that progress has been made in identifying all children with ASD.
  • In spite of the fact that developmental concerns are noted in many of children’s records by 3 years of age, fewer than half of children with ASD received a comprehensive developmental evaluation by this same age. This lag between first concern and first developmental evaluation may affect when children are being diagnosed and connected to the services they need.
  • ASD can be diagnosed as early as 2 years of age; however, about half of children were not diagnosed with ASD by a community provider until after 4 years of age.
  • Future efforts may emphasize the importance of screening young children with standard tools and connecting families to needed services before 3 years of age.
  • The percentage of children with ASD continues to be higher in New Jersey compared to other areas in the United States where CDC tracks ASD. It is not known exactly why this is so, but geographic differences in evaluation and diagnostic practices for children with developmental concerns may play a role.

How can this information be useful?

The latest findings may be used to

  • Promote early identification of ASD,
  • Plan for enhanced services and training,
  • Guide future research, and
  • Inform policies promoting improved health and quality of life outcomes for individuals with ASD.

How and where was this information collected?

NJAS uses a comprehensive, active case-finding method based on the analysis of information from the health and special education records of children who were 8 years old and living in one of 4 counties in New Jersey in 2014.

  • Tracking area: Essex, Hudson, Union, and Ocean counties
  • Children in tracking area: 32,935 8-year-olds
    • 41 percent white
    • 22 percent black
    • 31 percent Hispanic
    • 6 percent Asian or Pacific Islander
    • Less than 1 percent American Indian or Alaska Native

What else does NJAS do besides tracking ASD among 8-year-olds?

NJAS collaborates with the New Jersey Departments of Health and Education and local agencies and organizations that serve children with developmental disabilities and their families to track the number and characteristics of 4-year-olds and 8-year-olds with ASD and/or intellectual disability in select areas of New Jersey. NJAS offers information and training on the identification and diagnosis of ASD, sponsors presentations and workshops on ASD topics, and promotes innovative approaches to the detection of ASD.

“The CDC-ADDM Network and the New Jersey Autism Study data have been valuable resources, especially in our work in the early childhood space, toward understanding the scope and impact of ASD and related conditions on children, families and communities. These findings have been helpful to building and sustaining successful partnerships for ongoing promotion of parent engaged developmental monitoring and early identification of ASD and other developmental disabilities in our state.”
