Autism Prevalence in the US – 1970s to Today

Statistics from USA – is this an “epidemic”,  no government or health regulator are prepared to explain?

And a challenge for the reader: at what point in the future, these figures indicate that all Americans will have serious behaviour problems?

Meanwhile, can this trend explain the widespread intolerance and hostility between human beings and human groups with different sets of beliefs, instead of focusing on things in common and love for the fellow man (or woman)?
