correlation and causation) may match more than one target or description. the incidence of disease from yersinia, smallpox, tetanus, and polio has decreased dramatically in the last 150 years, and the rate of vaccination against yersinia, smallpox, tetanus, and polio has correspondingly increased. rates of dental cavities have increased in the last 100 years and so has the average sugar intake, which stimulates bacteria that erode tooth enamel. cell phone usage has increased dramatically in the last 100 years and so have autoimmune disorders such as multiple sclerosis. the rate of vaccination has increased in the last 100 years and so has the incidence of disorders such as autism.

Correlation means variables move together. Causation is a cause - effect link. In first case, vaccination likely causes disease decrease. In second, sugar causes cavities. Third and fourth may be just correlations.
