indicator

A substance that undergoes an observable change, usually a change of colour, when a chemical alteration occurs in its environment. Indicators may demonstrate changes in acidity, the presence of various substances, such as sugar or protein in body fluids, or alterations in the concentrations of substances. Indicators are widely used in chemistry and in clinical medicine.

Q. what do you think the reason would be? As per the latest statistics that 2 out of 150 kids born in the U.S. has autism, and the incidence rate is increasing, what do you think the reason would be?

A. The actual statistics is not 2 out of 150. It is 1 out of 150. I don't think autism is increasing, I think more children are being labeled as autistic - the condition is more well known than it was 20 years ago.
