Cultural pluralism is a sociological concept where smaller groups within a larger society maintain their unique cultural identities, values, and practices. These groups are accepted by the wider culture provided they are consistent with the laws and values of the broader society. It promotes diversity and coexistence rather than assimilation or the loss of distinct cultural heritage.

Pluralism is a social condition where diverse ethnic, religious, or cultural groups maintain their unique identities while participating in a shared political and economic system. The fundamental prerequisite for such a society is the peaceful coexistence of these various groups, where mutual respect and tolerance allow for the preservation of cultural diversity within a unified national framework.

Since the late 19th century, the economic divergence between Western Europe and many African nations has widened significantly. This is attributed to the compounding effects of sustained industrial growth, technological advancement, and institutional stability in Western Europe, contrasted with the challenges of colonial legacies, political instability, and slower economic development in many African nations. Consequently, the relative income gap between these two regions has expanded over the last century.

Social class categories used by researchers are often criticized for being arbitrary and artificial, meaning they lack a clear basis and are subjective. This implies that these categories may not accurately reflect the complexity of the American class system, as researchers must often define boundaries that do not exist in reality.

Modern sociological and economic discourse on stratification often bifurcates into two main perspectives: the functionalist view, which sees inequality as a necessary mechanism for societal efficiency, and the conflict view, which sees it as a source of systemic oppression. These two lenses provide the primary framework for analyzing why stratification persists in modern societies.

Crimes that do not involve physical violence, such as copyright infringement and price fixing, are often viewed with less public outrage than violent crimes. While these acts cause significant economic harm, the lack of direct physical confrontation often leads to a perception of lower severity in the public consciousness.

Standard income distribution measures typically focus on cash income. In-kind transfers, such as food stamps, housing vouchers, or subsidized healthcare, provide real economic value to low-income households. By failing to account for these non-cash benefits, standard metrics ignore the actual resources available to these households, thereby exaggerating the degree of inequality in living standards between the wealthy and the poor.

Structural functionalism is criticized for its subjective valuation of roles, such as the debate over the relative importance of athletes versus academics. It is also challenged for ignoring how privilege is inherited rather than earned, and for its inherent bias toward social stability, which may overlook the negative impacts of inequality on social justice and individual well-being.

In contemporary society, death is often perceived as an unnatural event rather than a routine part of life. This shift is largely attributed to advancements in medical technology, increased life expectancy, and the professionalization of end-of-life care, which have distanced the average person from the natural process of dying.

Horizontal mobility refers to the movement of an individual from one social position to another of the same rank. Since the change in job does not significantly alter the individual's socioeconomic status or prestige level, it is classified as horizontal rather than vertical mobility.
