Prevalence and Characteristics of Autism Spectrum Disorder Among Children Aged 8 Years — Autism and Developmental Disabilities Monitoring Network, 11 Sites, United States, 2012
Open accessAbstract
PROBLEM/CONDITION: Autism spectrum disorder (ASD). PERIOD COVERED: 2012. DESCRIPTION OF SYSTEM: The Autism and Developmental Disabilities Monitoring (ADDM) Network is an active surveillance system that provides estimates of the prevalence and characteristics of ASD among children aged 8 years whose parents or guardians reside in 11 ADDM Network sites in the United States (Arkansas, Arizona, Colorado, Georgia, Maryland, Missouri, New Jersey, North Carolina, South Carolina, Utah, and Wisconsin). Surveillance to determine ASD case status is conducted in two phases. The first phase consists of screening and abstracting comprehensive evaluations performed by professional service providers in the community. Data sources identified for record review are categorized as either 1) education source type, including developmental evaluations to determine eligibility for special education services or 2) health care source type, including diagnostic and developmental evaluations. The second phase involves the review of all abstracted evaluations by trained clinicians to determine ASD surveillance case status. A child meets the surveillance case definition for ASD if one or more comprehensive evaluations of that child completed by a qualified professional describes behaviors that are consistent with the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnostic criteria for any of the following conditions: autistic disorder, pervasive developmental disorder-not otherwise specified (including atypical autism), or Asperger disorder. This report provides ASD prevalence estimates for children aged 8 years living in catchment areas of the ADDM Network sites in 2012, overall and stratified by sex, race/ethnicity, and the type of source records (education and health records versus health records only). In addition, this report describes the proportion of children with ASD with a score consistent with intellectual disability on a standardized intellectual ability test, the age at which the earliest known comprehensive evaluation was performed, the proportion of children with a previous ASD diagnosis, the specific type of ASD diagnosis, and any special education eligibility classification. RESULTS: For 2012, the combined estimated prevalence of ASD among the 11 ADDM Network sites was 14.5 per 1,000 (one in 69) children aged 8 years. Estimated prevalence was significantly higher among boys aged 8 years (23.4 per 1,000) than among girls aged 8 years (5.2 per 1,000). Estimated ASD prevalence was significantly higher among non-Hispanic white children aged 8 years (15.3 per 1,000) compared with non-Hispanic black children (13.1 per 1,000), and Hispanic (10.2 per 1,000) children aged 8 years. Estimated prevalence varied widely among the 11 ADDM Network sites, ranging from 8.2 per 1,000 children aged 8 years (in the area of the Maryland site where only health care records were reviewed) to 24.6 per 1,000 children aged 8 years (in New Jersey, where both education and health care records were reviewed). Estimated prevalence was higher in surveillance sites where education records and health records were reviewed compared with sites where health records only were reviewed (17.1 per 1,000 and 10.4 per 1,000 children aged 8 years, respectively; p<0.05). Among children identified with ASD by the ADDM Network, 82% had a previous ASD diagnosis or educational classification; this did not vary by sex or between non-Hispanic white and non-Hispanic black children. A lower percentage of Hispanic children (78%) had a previous ASD diagnosis or classification compared with non-Hispanic white children (82%) and with non-Hispanic black children (84%). The median age at earliest known comprehensive evaluation was 40 months, and 43% of children had received an earliest known comprehensive evaluation by age 36 months. The percentage of children with an earliest known comprehensive evaluation by age 36 months was similar for boys and girls, but was higher for non-Hispanic white children (45%) compared with non-Hispanic black children (40%) and Hispanic children (39%). INTERPRETATION: Overall estimated ASD prevalence was 14.5 per 1,000 children aged 8 years in the ADDM Network sites in 2012. The higher estimated prevalence among sites that reviewed both education and health records suggests the role of special education systems in providing comprehensive evaluations and services to children with developmental disabilities. Disparities by race/ethnicity in estimated ASD prevalence, particularly for Hispanic children, as well as disparities in the age of earliest comprehensive evaluation and presence of a previous ASD diagnosis or classification, suggest that access to treatment and services might be lacking or delayed for some children. PUBLIC HEALTH ACTION: The ADDM Network will continue to monitor the prevalence and characteristics of ASD among children aged 8 years living in selected sites across the United States. Recomme

Written from the paper’s full text.
TL;DR
In 2012, the ADDM Network estimated ASD prevalence among children aged 8 years across 11 U.S. sites at 14.5 per 1,000 (one in 69), with wide variation by site and higher estimates where both education and health records were reviewed. Prevalence was higher among boys and non-Hispanic white children, and although 87% had a developmental concern by age 36 months, the median age at earliest known comprehensive evaluation was 40 months.
Key findings
- Combined estimated ASD prevalence was 14.5 per 1,000 (one in 69) children aged 8 years; site estimates ranged from 8.2 per 1,000 (Maryland, health records only) to 24.6 per 1,000 (New Jersey). Sites reviewing education and health records had higher estimated prevalence than health-records-only sites (17.1 vs. 10.4 per 1,000; PR: 1.6; 95% CI: 1.5–1.7; p<0.001).
- Estimated prevalence was 23.4 per 1,000 among boys and 5.2 per 1,000 among girls (male-to-female PR: 4.5; 95% CI: 4.2–4.8). By race/ethnicity, estimates were 15.3 per 1,000 for non-Hispanic white, 13.1 for non-Hispanic black, 11.4 for Asian/Pacific Islander, and 10.2 for Hispanic children.
- Among 3,353 children with intellectual ability data in nine areas, 31.4% were in the intellectual disability range (IQ ≤70), 24.6% in the borderline range (IQ 71–85), and 44.1% in the average or above-average range (IQ >85). Estimated prevalence was 3.9 per 1,000 for ASD with intellectual disability and 8.6 per 1,000 for ASD without intellectual disability.
- Overall, 82% had a previous ASD diagnosis or educational classification; 74% had an earliest known DSM-IV-TR ASD diagnosis, including autistic disorder (46%), ASD-NOS/PDD-NOS (44%), and Asperger disorder (10%). The median age at earliest known comprehensive evaluation was 40 months, and 43% had an earliest known comprehensive evaluation by age 36 months.
Methods
- Active, multisite, records-based surveillance in 11 ADDM Network sites among children born in 2004 and aged 8 years in 2012; the surveillance area included 346,978 children aged 8 years.
- Two-phase case ascertainment: screening and abstraction of education and health records, followed by clinician review of composite records against the DSM-IV-TR-based ASD surveillance case definition (autistic disorder, PDD-NOS, or Asperger disorder).
- Prevalence was calculated using NCHS vintage 2014 postcensal bridged-race population estimates and stratified by site, sex, and race/ethnicity; analyses used Pearson chi-square tests, prevalence ratios, and median tests, with clinician-review reliability of 90.4% agreement (κ = 0.8).
Limitations
- The paper states seven limitations: reliance on available source records; varied source-record types across sites and possible underestimation where education records were unavailable; education records generally unavailable for private-school or home-schooled children; surveillance areas not representative of the U.S. or their states; nondecennial population estimates may have error; birth-certificate restriction may not fully eliminate bias from children who moved; and broad race/ethnicity categories, including inability to distinguish Hispanic children by primary household language.
- The paper also notes that prevalence estimates do not reflect the missing-record adjustment, and that 2010–2012 comparisons were restricted to eight sites with comparable surveillance areas and record source types; individual site changes were not clearly explained and may reflect local health-care variation or record-retention changes.

The paper relies on this without support.
The ADDM ASD surveillance case criteria accurately identify children with ASD.
“Of these 9,629 children, 5,021 (52%) met the ASD surveillance case criteria.”
The paper relies on this without support.
Children with ASD who had data on intellectual ability are representative of all children with ASD in the nine areas.
“In these nine areas, 3,353 (80%) of 4,189 children with ASD had data on intellectual ability”
The paper relies on this without support.
Missing records would have had a similar ASD case yield to reviewed records, so the estimated potential increase is valid.
“An evaluation of the effect of missing records suggested that estimated ASD prevalence might have increased by 0.1% (in Wisconsin) to 3.3% (in Utah) if missing records had been available for review.”

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 2026-10-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
