Unformatted text preview: Population Pyramids Detail the birth rates, processes throughout the life time and life expectancy Important to remember that they represent a snapshot of a particular point in time (rather than the way things will have to be) Macrostratification and Population Trends Stratification, as we have discussed, means the allocation of resources Population pyramids can detail some of the largest (most macro) trends in stratification: who lives and who dies They can detail large scale effects occurring in countries Population Pyramids One of the most consistent regularities across industrialized societies is that women, on the average live longer than men Right now, women tend to outlive men in the U.S. by almost 7 years Population Pyramids Birth rates: biological consistency that the birth rate is around 105 (the number of males per 100 females) When birth rates vary from this, it is a sign that there is some intervention So for example, there are skewed sex ratios in China and Korea and India--what does this represent? Sex ratios are around 117! United States, 2000, population pyramid United Kingdom, 2000, population pyramid China, 2000, population pyramid Afghanistan, 2000, population pyramid Gender and Mortality--What accounts for the differences? Biology? What evidence would you look for that would support a biological argument? Marital status is also related to life expectancy, at least for men for women, this relationship is not as strong Gender related death rates The male death rate from heart disease is about 84% higher than the female death rate from heart disease It is suggested that some of the differences due to behaviors that are gender-typed; in particular, to Type A personalities (competitive, impatient, aggressive, etc) Also, there Type D personalities-strong, silent types, that seem more prone to heart attacks Heart attacks (continued_ Some studies indicate that women who are employed outside the home appear to be healthier than nonemployed women (why might this be the case--aren't there competing demands?) Race is a very important factor in health--African Americans are much more likely to suffer from high blood pressure than Whites (issues related to stress) Also African Americans are less likely to get medical treatment Cancer Men's death rate due to cancer is 40% higher than women's cancer death rate (National Center for Health Statistics, 2000) Much of this appears to be due to smoking (and now, in fact, rates for women who smoked are "catching up" to those for men) Eating Disorders These disorders can vary from obesity (25% over average weight of someone at age and height) to anorexia (25% loss of original body weight with refusal to eat) More men are overweight (59%) than women (50%), but more women (28%) are obese than men (20%) http://www.cdc.gov/nccdphp/dnpa/obesity/trend/ maps/ ...
