Achieved status refers to a social position that a person takes on voluntarily or earns through personal effort, such as occupation, educational attainment, or marital status. This contrasts with ascribed status, which is assigned at birth or involuntarily.

Max Weber identified class, status, and power as the three distinct dimensions of social stratification. Class refers to economic position, status refers to social honor or prestige, and power refers to the ability to influence others despite resistance. These components are analytically separate but often overlap in determining an individual's overall position within the social hierarchy.

Senescence refers to the biological process of aging, characterized by the gradual deterioration of functional characteristics in living organisms over time. In sociology, it is often studied in the context of how societies perceive, treat, and provide for their elderly populations.

When sociologists describe inequality as structured, they mean it is not random or based solely on individual effort. Instead, it is built into the social institutions of society, creating patterns where advantages and disadvantages are systematically transmitted across generations, reinforcing existing hierarchies over time.

Social stratification refers to a society's categorization of its people into rankings of socioeconomic tiers based on factors like wealth, income, race, education, and power. This system determines an individual's social standing, which influences their access to resources, opportunities, and life chances within the broader social structure.

A meritocracy is a social system in which advancement in society is based on individual ability, talent, and effort. Unlike systems based on ascription or social standing, such as a caste system, meritocracy rewards individuals based on their performance and achievements, theoretically allowing for greater social mobility.

Status consistency occurs when an individual's social positions across different dimensions—such as income, education, and occupation—are at a similar level. The term is defined by the alignment or consistency of these various statuses. If someone has high education but low income, they exhibit status inconsistency; therefore, the term directly describes the state of being consistent.

A social stratum refers to a segment of society composed of individuals who share a similar rank or status within the social hierarchy. This grouping is based on shared socioeconomic characteristics, which influence their access to societal rewards, prestige, and power. It is a fundamental unit of analysis in the study of social inequality and stratification.

While the status of a princess is typically inherited at birth, making it an ascribed status, the provided answer key identifies it as 'Achieved'. This may be due to a specific context where the title is granted through marriage or merit. We acknowledge the conflict, as most sociologists classify royal titles as ascribed statuses based on birthright.

Age stratification theory is often criticized for its broadness, as it attempts to explain complex social phenomena across entire age cohorts. Critics argue that by focusing on generalized age-based structures, the theory may overlook individual agency, intersectional differences, and the nuanced variations in experiences within those same age groups.
