A Summary of the Index of Dissimilarity The index of dissimilarity is a measurement of segregation that actuates the evenness with which members in two racial groups are spread across neighborhoods within a city or metropolitan area. Here, evenness measures the consistency of two racial groups coexisting in neighborhoods in relative proportions that parallel the total respective racial populations of the city. In a hypothetical city consisting of 60% non-Hispanic black people and 40% non-Hispanic white people, complete segregation would indicate that all members living in each neighborhood within that city will be either non-Hispanic black people or non-Hispanic white people. Contrastingly, in another hypothetical city consisting of these two races with respective proportions, complete integration would indicate that each neighborhood within that city contains exactly 60% of non-Hispanic black people and 40% of non-Hispanic white people. The evenness of the spread of racial groups is similar to a peanut butter and jelly sandwich. Imagine that the sandwich represents the city and each bite of the sandwich represents a neighborhood. A sandwich integrated …show more content…

By taking one-half of the grand sum of the absolute differences in the proportions of two races in each neighborhood with respect with to their whole racial population in the city, the index of dissimilarity generates a numerical value between 0 and 1 that can be used to interpret the level of segregation present in a city. An index of dissimilarity of less than 0.3 reveals that there is low segregation between the two compared races in the city, whereas values between 0.3 and 0.6, and greater than 0.6 represent moderate and high segregation,

  • Segregation In The Film: Do The Right Thing

    1489 Words  | 3 Pages

    A few areas that segregation is predominately seen in the United States is housing, income, and racial. In the film Do the Right Thing we see all three forms of segregation but income segregation is not as fairly presented as housing and racial. In housing segregation, groups can be segregated in five ways evenness, exposure, concentration, centralization, and clustering. These groups are not mutually exclusive, given race and socioeconomic status. But when a group is segregated in high in four of the five ways it is called hypersegregation. In the film we can infer that housing segregation is occurring because the neighborhood where the film takes place is predominately Black. And as we discussed in class, one of the five ways housing segregation is measured is evenness this is being the degree to which a group is spread in equal proportions among other groups across neighborhoods. This is how housing segregation is portrayed in the

    New York City, known for its crowded streets and subways, is filled with people of different ethnicities; those who look, talk and behave differently from others around them. After all, it is called the “melting pot” of the United States for a reason, a place where people from various backgrounds come to assimilate into the American Society. These different humans are identified and categorized into groups based on their skin color and physical features, giving rise to the concept of race.

  • Why Similarity Doesn't Mean Equality

    831 Words  | 2 Pages

    In David Schmidtz’s article “Are All Species Equal?” he discusses species egalitarianism and if it has any application or standing in the philosophical discussion of environmental ethics. One of the given arguments equates speciesism to racism. These two terms, down to their basic definitions, are so fundamentally different that it is difficult to compare them. Racism is the discrimination of a race of people based on the culture, physical features and tone of speech among other things. The parameters in which racism occurs and what determines superiority of one group of people over another is challenging to translate over into the realm of speciesism. For how are we to determine which traits are superior? In the Jim Crow era white heritage was hailed to be purer then African heritage, so in this racist instance we are comparing the same trait. Applying this to animals and plants is rather difficult. There is no black and white commonality between species. Comparing one species to another using any single trait has the possibility of alienating more animals and plants then it does uniting them in equality. One could argue that cognitive thinking is the standard in which we would base any sort of hierarchy. However, this places humans at the top and since we were the ones who set up the parameters initially it’s a bit farfetched. So by what basis do we judge other species? Sticking with outside appearances a thick fur coat could be an appropriate standard. Bears and huskies would be superior, but this alienates birds, reptiles and humans. If we digress to physical skill: if it is speed the peregrine falcon comes as the dominant species. When you get down to it, one of the real difficulties is comparing species against one another. ...

    Despite increased diversity across the country, America’s neighborhoods remain highly segregated along racial and ethnic lines. Residential segregation, particularly between African-Americans and whites, persists in metropolitan areas where minorities make up a large share of the population. This paper will examine residential segregation imposed upon African-Americans and the enormous costs it bears. Furthermore, the role of government will be discussed as having an important role in carrying out efforts towards residential desegregation. By developing an understanding of residential segregation and its destructive effects, parallels may be drawn between efforts aimed at combating such a grave societal problem and furthering social justice.

    Despite general declining rates of morbidity and mortality in the United States over the past century, African-Americans still find themselves at a health disadvantage and account for more than 40% of diagnosed cases of chronic diseases such as heart disease, diabetes, arthritis, asthma, obesity and cancer . Studies within the fields of sociology and public health have directed their focus towards individual-level determinants of health such as socio-economic status and individual health behaviors. However, there has been insufficient attention to how and why place and neighborhood contribute to racial/ethnic health disparities. This analysis examines the health implication of racial segregation as a result of gentrification on African Americans, explores systems of segregation measurement, and proposes ways to move beyond traditional public health and health care approaches to impact relevant policy.

    Racial segregation is the separation of humans into racial or other ethnic groups in daily life. It may apply to activities such as eating in a restaurant, drinking from a water fountain, using a public toilet, attending school, going to the movies, riding on a bus, or renting or purchasing a home (Wikipedia, 2017). Segregation is defined by the European Commission against Racism and Intolerance as "the act by which a (natural or legal) person separates other persons on the basis of one of the enumerated grounds without an objective and reasonable justification, in conformity with the proposed definition of discrimination (Explanatory memorandum, Para. 16).

    Legal segregation may have ended more than 50 years ago, but in many parts of the country Americans of different races are not neighbors. According to a recent State University of New York at Stony Brook census ranks Long Island as the third most racially segregated suburban region in the country, behind the suburbs of Newark and Cleveland.

  • Analysis Of Elizabeth Anderson's Article: The Imperative Of Integration

    988 Words  | 2 Pages

    She argues that segregation has larger implications than just material goods, so programs that merely redistribute these goods do not fully solve the problem. She discusses three additional effects that only integration can mitigate: “ social/cultural capital inequality, racial stigmatization, and anti-democratic effects” (Anderson 2). Anderson points out that members of isolated communities do not receive similar opportunities, “[undermining] disadvantaged groups’ accumulation of the cultural capital needed for advancement” (2). In addition, she argues that geographic isolation reinforces negative stereotypes, functioning to stigmatize minorities or members of out-groups in general. Racial stigmas do not just occur only with extremist thinking. Anderson points out that, “even people who consciously reject anti-black stereotypes have been found to discriminate against blacks” (17). She finally argues that segregation causes a lack of “both communication and accountability” between political elites and isolated minorities (17). Not only are these three effects byproducts of community separation, but they cannot be fixed simply by moving resources around. Anderson contends that integration is the only answer and is enacted through stages of formal desegregation, spatial integration, and formal social integration. These steps are the only way to ensure that isolated minorities will have equality under law, sharing of public institutions such as schools, and cooperation within those institutions leading to better

    Care and education have become a part of children’s daily lives in Ireland and England outside the home in childcare services. The Early Years Foundation Stage (EYFS) is the statutory curriculum framework for children up to the age of five in England. It was first introduced in 2008 and on the 1st of September 2012 a new revised document was published. Aistear, published in 2009, is Ireland’s first early year’s curriculum framework for children from birth to six years of age. A curriculum framework is a scaffold or support for the development of a curriculum that can be used in childcare settings. A curriculum framework can also be used in partnership with parents when developing a curriculum. This paper will compare and contrast these two curriculum frameworks in relation to philosophy, content, pedagogical practices and expected/targeted outcomes for children. Due to the limits of this paper, it will only be possible to develop an overview of the similarities and differences.
