HLTB01H3S: Health, Aging and the Life Cycle Department of Health Studies University of Toronto at Scarborough Winter 2010 Instructor: Anna Walsh. Term: Fall 2008 Mondays 3 p.m. - 5 p.m. Lecture Room: Room AA112 January 252010. The Aging of the Population. A&G: Chapter 2 -Demography of Aging. There has been a dramatic change in population demographics in the last century that continues to provide ongoing challenges for health care providers to provide adequate services to the increasing number of older adults in the world. Population Aging in the United States: In 1905, children and young people represented a large segment of the population with only a small percentage of individuals of 65 years of age and older. This created a pyramid-shaped population profile, which results from high fertility rates and high mortality rates It is projected that as many as 70 million people in the US will be 65 years and older by 2030 In 1900, there were only approximately 100,000 people who were over the age of 85 in the United States. The probability of reaching 100 years of age improved th during the 20 century. In 1879, a person had a 1400 chance of living to be 100 years old, but as of 1980, there was a 187 chance to living to 100. 85+ is the fastest growing portion of the older population (3.1 million in 1990, to 4.2 million in 2000) Definitions: Total Dependency Ratio (TDR) compares the number of economically nonproductive citizens (below 18 and above 65 years) with the number of working-aged adults Equation: TDR = (a+c) b a=children <18, b=adults 18 to 65, c=adults 65+ 1
