title: Studies of mortality and morbidity data. II. Mortality from all causes in Ontario Counties during 1964-1968.
abstract: Age-adjusted mortality rates, for all causes of death, are tabulated for all ages by sex for the 55 Ontario counties and districts. The rates are based on all deaths of Ontario residents during 1964-1968 and 1966 census populations. The consistent trends in rates, both for the two sexes and for various 10- and 20-year age groups, indicate that there is a region of about eight adjoining counties, across the center of the province, which has abnormally high mortality, and two regions to the east and west of York, each consisting of three adjoining counties which have abnormally low mortality. The relevance of these findings to aging studies is indicated, and possible further investigations of them are discussed.
