The numbers of children being
diagnosed with autism is rising at a meteoric rate -- too fast to be explained
by more frequent diagnostic recognition.
The following figures are statistics
maintained by the Department of Education for children with autism aged
6-21, who are given Special Education services under IDEA (the Individuals
with Disabilities Education Act).
The totals reflect each of
the 50 states, the District of Columbia and Puerto Rico, with combined
totals below.
Where
increase percentages rise past a certain point, approximately 5000%, the
rate is given below as "near infinite."
Projections for coming years
are listed beneath, based on current figures, rates, and typical research/intervention
patterns. The increasing numbers of students with autism can also be seen
clearly when statistics are examined by age group.
Below the nationwide charts
are the numbers of New Jersey students with autism as of December 1, 2001
(for the calendar year 2001/2002), broken down by chronological age, taken
from data compiled for the upcoming 24th Annual Report to Congress on
the Implementation of the Individuals with Disabilities Education Act
by the Office of Special Education Programs, Trenton, New Jersey.
Explanations
For The Surge In Autism Rates Abound
One recent
perspective appears in the January 6, 2002 Sunday Herald, United Kingdom.
The argument that autism is
primarily a genetic phenomenon has been the leading one over the decades,
and still receives significant -- probably the majority -- of scientific
funding; however, an astute delineation of the impacts of environmental
factors versus genetics on disease incidence was provided by Dr. Bengt
Olle Bengtsson, Professor of Evolutionary Genetics and Chairman of the
Department of Genetics at Lund University, Sweden, for FEATNews, April
1, 2002.

for 2000-2001; at [website],

Reports to Congress on the Implementation of the Individuals with Disabilities
Education Act, 1996 forward.
