Research findings that examine the importance of the social determinants of health provide insights into: (a) the general improvement in health among citizens in developed nations over the past 100 years; (b) the health inequalities observed among populations within nations; and (c) differences in overall national health among both developed (e.g., between Sweden versus Canada versus the USA) and developing nations (e.g., between Cuba versus Argentina versus Brazil).
