The Demography of Aging and Disability

  • Samir K. Sinha
  • Colleen Christmas


Over the previous century, there has been an extraordinary demographic shift which will no doubt persist well into this one. The lengthening of life span by over 50% and consequent increase in the proportion of the population that we refer to as the “elderly” has created a new and different social, economic, and medical imperative. We are now faced with the daunting task of providing health and social care for a huge number of persons living well into old age with more chronic illnesses, and increased needs and expectations. Anticipating the kinds of health care services, this population requires coordinated and creative efforts by many sectors of society and considerable educational and research activities to determine the best methods to deliver services. Indeed, this textbook has been written to respond to some of these challenges by addressing the specialized needs of older persons facing surgery.
