Resources by state

Autism resources by state

Every state and DC has its own hub: where to start with early intervention, school evaluations, Medicaid, and free rights help — with key numbers from named public sources. City guides nest under their state.

How we use numbers

State figures come from primary public sources — U.S. Census child population and U.S. Department of Education IDEA Section 618 child counts. A number appears on a hub only once its source can be named, and city pages never invent local figures.

Systems links and table figures verified as of August 29, 2026.Census Vintage 2023 (children 0–17). IDEA Autism ages 3–21 from OSEP §618, school year 2022–23 (when published). Program names and phones are checked against the named agency site; confirm on that site before you act.

The short answer

  • Pick your state above for official Part C early intervention, state education agency, Medicaid, and Protection & Advocacy entry points.
  • Numbers on each hub are Census ages 0–17 and IDEA §618 served counts (when published) — not modeled autism totals from national rates.
  • Federal IDEA rights apply everywhere; how you open the door (program names, phones, waivers) is state-specific and verified on each hub.

Data policy — only verified figures

  • Children ages 0–17. Summed from the U.S. Census Bureau Vintage 2023 SC-EST2023-AGESEX-CIV file (civilian population by single year of age). Primary source linked on every state page.
  • IDEA Autism ages 3–21. From U.S. Department of Education OSEP Section 618 Part B child count (SY 2022–23): children served under the Autism disability category. A served administrative count — not a full population census of every autistic child.
  • CDC ADDM 1 in 31. Quoted only as national monitoring-site context (2022, 16 sites, 8-year-olds). We do not multiply it by state population to invent a headcount.
  • Access checklist. Points only for fields with a cited source: ECTA Part C website / referral phone / referral URL; KFF Medicaid expansion status; presence of SEA, Medicaid, and P&A URLs in this catalog.
  • What is not on these pages. No estimated autism headcounts, no invented prevalence by state, no private clinic rankings. For IDEA special-education autism child counts, use OSEP Section 618 products from the U.S. Department of Education when you need that specific measure.
  • City pages. City guides nest under each state hub and list local intake contacts and resources. We only show a city number when a primary source exists for that place — and a resource's claims about itself are attributed to its own website and dated, never asserted by us.

How the systems fit together

Public systems open in a set order. Your state hub names the doors; these guides explain what happens when you walk through.
