Prevalence and Early Identification of Autism Spectrum Disorder Among Children Aged 4 and 8 Years — Autism and Developmental Disabilities Monitoring Network, 16 Sites, United States, 2022
Open accessAbstract
Problem/Condition: Autism spectrum disorder (ASD). Period Covered: 2022. Description of System: The Autism and Developmental Disabilities Monitoring Network is an active surveillance program that estimates prevalence and characteristics of ASD and monitors timing of ASD identification among children aged 4 and 8 years. In 2022, a total of 16 sites (located in Arizona, Arkansas, California, Georgia, Indiana, Maryland, Minnesota, Missouri, New Jersey, Pennsylvania, Puerto Rico, Tennessee, Texas [two sites: Austin and Laredo], Utah, and Wisconsin) conducted surveillance for ASD among children aged 4 and 8 years and suspected ASD among children aged 4 years. Surveillance included children who lived in the surveillance area at any time during 2022. Children were classified as having ASD if they ever received 1) an ASD diagnostic statement in a comprehensive developmental evaluation, 2) autism special education eligibility, or 3) an ASD International Classification of Diseases, Ninth Revision (ICD-9) code in the 299 range or International Classification of Diseases, Tenth Revision (ICD-10) code of F84.0, F84.3, F84.5, F84.8, or F84.9. Children aged 4 years were classified as having suspected ASD if they did not meet the case definition for ASD but had an evaluator's suspicion of ASD documented in a comprehensive developmental evaluation. Results: Among children aged 8 years in 2022, ASD prevalence was 32.2 per 1,000 children (one in 31) across the 16 sites, ranging from 9.7 in Texas (Laredo) to 53.1 in California. The overall observed prevalence estimate was similar to estimates calculated using Bayesian hierarchical and random effects models. ASD was 3.4 times as prevalent among boys (49.2) than girls (14.3). Overall, ASD prevalence was lower among non-Hispanic White (White) children (27.7) than among Asian or Pacific Islander (A/PI) (38.2), American Indian or Alaska Native (AI/AN) (37.5), non-Hispanic Black or African American (Black) (36.6), Hispanic or Latino (Hispanic) (33.0), and multiracial children (31.9). No association was observed between ASD prevalence and neighborhood median household income (MHI) at 11 sites; higher ASD prevalence was associated with lower neighborhood MHI at five sites.Record abstraction was completed for 15 of the 16 sites for 8,613 children aged 8 years who met the ASD case definition. Of these 8,613 children, 68.4% had a documented diagnostic statement of ASD, 67.3% had a documented autism special education eligibility, and 68.9% had a documented ASD ICD-9 or ICD-10 code. All three elements of the ASD case definition were present for 34.6% of children aged 8 years with ASD.Among 5,292 (61.4% of 8,613) children aged 8 years with ASD with information on cognitive ability, 39.6% were classified as having an intellectual disability. Intellectual disability was present among 52.8% of Black, 50.0% of AI/AN, 43.9% of A/PI, 38.8% of Hispanic, 32.7% of White, and 31.2% of multiracial children with ASD. The median age of earliest known ASD diagnosis was 47 months and ranged from 36 months in California to 69.5 months in Texas (Laredo).Cumulative incidence of ASD diagnosis or eligibility by age 48 months was higher among children born in 2018 (aged 4 years in 2022) than children born in 2014 (aged 8 years in 2022) at 13 of the 15 sites that were able to abstract records. Overall cumulative incidence of ASD diagnosis or eligibility by age 48 months was 1.7 times as high among those born in 2018 compared with those born in 2014 and ranged from 1.4 times as high in Arizona and Georgia to 3.1 times as high in Puerto Rico. Among children aged 4 years, for every 10 children meeting the case definition of ASD, one child met the definition of suspected ASD.Children with ASD who were born in 2018 had more evaluations and identification during ages 0-4 years than children with ASD who were born in 2014 during the 0-4 years age window, with an interruption in the pattern in early 2020 coinciding with onset of the COVID-19 pandemic.Overall, 66.5% of children aged 8 years with ASD had a documented autism test. Use of autism tests varied widely across sites: 24.7% (New Jersey) to 93.5% (Puerto Rico) of children aged 8 years with ASD had a documented autism test in their records. The most common tests documented for children aged 8 years were the Autism Diagnostic Observation Schedule, Autism Spectrum Rating Scales, Childhood Autism Rating Scale, Gilliam Autism Rating Scale, and Social Responsiveness Scale. Interpretation: Prevalence of ASD among children aged 8 years was higher in 2022 than previous years. ASD prevalence was higher among A/PI, Black, and Hispanic children aged 8 years than White children aged 8 years, continuing a pattern first observed in 2020. A/PI, Black, and Hispanic children aged 8 years with ASD were also more likely than White or multiracial children with ASD to have a co-occurring intellectual disability. Identification by age 48 months was higher among children born in 2018 com
Overview
AI snapshot
Written from the paper’s full text.
TL;DR
In 2022, ASD prevalence among children aged 8 years across 16 ADDM Network sites was 32.2 per 1,000 (one in 31), with wide site variation and higher prevalence among several racial and ethnic groups than White children. Early identification by age 48 months was 1.7 times as high among children born in 2018 compared with those born in 2014.
Key findings
- Among children aged 8 years, ASD prevalence was 32.2 per 1,000, ranging from 9.7 in Texas (Laredo) to 53.1 in California; prevalence was 49.2 per 1,000 among boys and 14.3 among girls (male-to-female ratio 3.4).
- Prevalence was lower among White children (27.7) than A/PI (38.2), AI/AN (37.5), Black (36.6), Hispanic (33.0), and multiracial children (31.9).
- Among 5,292 children aged 8 years with ASD and cognitive data, 39.6% had intellectual disability (IQ ≤70); median age of earliest known ASD diagnosis was 47 months.
- Cumulative incidence of ASD diagnosis or eligibility by age 48 months was 1.7 times as high among children born in 2018 (22.6 per 1,000) compared with children born in 2014 (13.1 per 1,000); suspected ASD among children aged 4 years was 3.1 per 1,000, or one suspected case for every 10 children meeting ASD case definition.
Methods
- Active surveillance in 16 sites in 2022 among children aged 4 and 8 years, using health and education records; ASD case definition required an ASD diagnostic statement, autism special education eligibility, or qualifying ICD-9/ICD-10 code, with suspected ASD defined for children aged 4 years.
- Record abstraction was completed for 15 sites for 8,613 children aged 8 years who met the ASD case definition; analyses included prevalence by sex, race and ethnicity, neighborhood median household income, and social vulnerability index.
- Prevalence was calculated per 1,000 children, with Bayesian hierarchical and random-effects models also used for overall estimates; cumulative incidence by age 48 months and monthly evaluation/identification patterns were compared between birth cohorts.
Limitations
- The paper states that ADDM surveillance populations are not nationally representative, overall estimates do not capture full community variability, and data quality depends on availability and completeness of records, which vary by site and source.
- The paper also states that sources reviewed generally do not include private schools or primary care providers, and that the surveillance definition of intellectual disability is not the same as a clinical diagnosis; IQ in young children may lack stability and adaptive behavior assessments are often absent.
- Evident from the text: Indiana was excluded from record-abstraction analyses because ASD diagnostic statement data were unavailable, and several site-specific estimates were suppressed because relative standard error was ≥30%.

The Discussion (page unavailable) says 2020 was the first year the ADDM Network reported lower ASD prevalence among White children aged 8 years than among other groups; the Results specifically show higher prevalence among Black and Hispanic children. The Results’ Figure 1 and Methods (pages unavailable) use median household income tertiles for SES and show no statistically significant prevalence trend in 8 of 11 sites. This supports the citing sentence’s site-level SES statement, though it does not establish that no association exists. (LLM, conf=0.92)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
