the group of people with typical-everyday jobs that pay significantly more than the poverty line. Examples of these types of jobs are factory workers, salesperson, teacher, cooks and nurses. There is a new trend by some scholars which assumes that the size of the middle class in every society is the same. For example, in paradox of interest theory, middle class are those who are in 6th–9th decile groups which hold nearly 12% of the whole society's wealth. Lower class Lower class (occasionally described as working class) are those employed in low-paying wage jobs with very little economic security. The term "lower class" also refers to persons with low income. The working class is sometimes separated into those who are employed but lacking financial security (the "working poor") and an underclass—those who are long-term unemployed and/or homeless, especially those receiving welfare from the state. The latter is today considered analogous to the Marxist term "lumpenproletariat". However, during the time of Marx's writing the lumpenproletariat referred to those in dire poverty; such as the homeless. Members of the working class are sometimes called blue-collar workers. Consequences of class position A person's socioeconomic class has wide-ranging effects. It can determine the schools they are able to attend, their health, the jobs open to them, when they exit the labour market, whom they may marry and their treatment by police and the courts. Angus Deaton and Anne Case have analyzed the mortality rates related to the group of white, middle-aged Americans between the ages of 45 and 54 and its relation to class. There has been a growing number of suicides and deaths by substance abuse in this particular group of middle-class Americans. This group also has been recorded to have an increase in reports of chronic pain and poor general health. Deaton and Case came to the conclusion from these observations that because of the constant stress that these white, middle aged Americans feel fighting poverty and wavering between the middle and lower classes, these strains have taken a toll on these people and affected their whole bodies. Social classifications can also determine the sporting activities that such classes take part in. It is suggested that those of an upper social class are more likely to take part in sporting activities, whereas those of a lower social background are less likely to participate in sport. However, upper-class people tend to not take
