Abstract
This scientific poster presentation uses data from the Ontario Health Survey (a large population-based health survey, carried out in a population of 10 million people in 1990) to estimate the number of people reporting a variety of chronic conditions, including eye diseases, diabetes, heart disease and other conditions not associated with driving risk or driving problems. There is little evidence in the results that the presence of disease had any direct effect on whether people drive, how much they drive or how safely they drive. Other factors such as age, sex or gainful employment, are frequently more important.
