Nationality in the context of "Legal"

Citizenship is a membership and allegiance to a sovereign state.

Though citizenship is often conflated with nationality in today's English-speaking world, international law does not usually use the term citizenship to refer to nationality; these two notions are conceptually different dimensions of collective membership.

The Roman people was the ethnicity and the body of Roman citizens(Latin: Rōmānī; Ancient Greek: Ῥωμαῖοι Rhōmaîoi) during the Roman Kingdom, the Roman Republic, and the Roman Empire. This concept underwent considerable changes throughout the long history of the Roman civilisation, as its borders expanded and contracted. Originally only including the ethnic Latins from Rome itself, Roman citizenship was extended to the rest of the Italic peoples by the 1st century BC and to nearly every subject of the Roman empire in late antiquity. At their peak, the Romans ruled large parts of Europe, the Near East, and North Africa through conquests made during the Roman Republic and the subsequent Roman Empire. Although defined primarily as a citizenship, "Roman-ness" has also and variously been described as a cultural identity, a nationality, or a multi-ethnicity that eventually encompassed a vast regional diversity.

Citizenship grants, demographic growth, and settler and military colonies rapidly increased the number of Roman citizens. The increase achieved its peak with Emperor Caracalla's AD 212 Antonine Constitution, which extended citizenship rights to all free inhabitants of the empire. Roman identity provided a larger sense of common identity and became important when distinguishing from non-Romans, such as barbarian settlers and invaders. Roman culture was far from homogeneous; though there was a common cultural idiom, one of the strengths of the Roman Empire was also its ability to incorporate traditions from other cultures, notably but not exclusively Greece.

Demography (from Ancient Greek δῆμος (dêmos) 'people, society' and -γραφία (-graphía) 'writing, drawing, description') is the statistical study of human populations: their size, composition (e.g., ethnic group, age), and how they change through the interplay of fertility (births), mortality (deaths), and migration.

Demographic analysis examines and measures the dimensions and dynamics of populations; it can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration. In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of the population. Demographic analysis estimates are often considered a reliable standard for judging the accuracy of the census information gathered at any time. In the labor force, demographic analysis is used to estimate sizes and flows of populations of workers; in population ecology the focus is on the birth, death, migration and immigration of individuals in a population of living organisms, alternatively, in social human sciences could involve movement of firms and institutional forms. Demographic analysis is used in a wide variety of contexts. For example, it is often used in business plans, to describe the population connected to the geographic location of the business. Demographic analysis is usually abbreviated as DA. For the 2010 U.S. Census, The U.S. Census Bureau has expanded its DA categories. Also as part of the 2010 U.S. Census, DA now also includes comparative analysis between independent housing estimates, and census address lists at different key time points.

An oath of allegiance is an oath whereby a subject or citizen acknowledges a duty of allegiance and swears loyalty to a monarch or a country. In modern republics, oaths are sworn to the country in general, or to the country's constitution. For example, officials in the United States, take an oath of office that includes swearing allegiance to the United States Constitution. However, typically in a constitutional monarchy, such as in the United Kingdom, Australia, and other Commonwealth realms, oaths are sworn to the monarch. Armed forces typically require a military oath.

In feudal times, a person would also swear allegiance to their feudal superiors. To this day the oath sworn by freemen of the City of London contains an oath of obedience to the Lord Mayor of the City of London.

Cultural identity is a part of a person's identity, or their self-conception and self-perception, and is related to nationality, ethnicity, religion, social class, generation, locality, gender, or any kind of social group that has its own distinct culture. In this way, cultural identity is both characteristic of the individual but also of the culturally identical group of members sharing the same cultural identity or upbringing. Cultural identity is an unfixed process that is continually evolving within the discourses of social, cultural, and historical experiences. Some people undergo more cultural identity changes as opposed to others, those who change less often have a clear cultural identity. This means that they have a dynamic yet stable integration of their culture.

There are three pieces that make up a person's cultural identity: cultural knowledge, category label, and social connections. Cultural knowledge refers to a person's connection to their identity through understanding their culture's core characteristics. Category label refers to a person's connection to their identity through indirect membership of said culture. Social connections refers to a person's connection to their identity through their social relationships. Cultural identity is developed through a series of steps. First, a person comes to understand a culture through being immersed in those values, beliefs, and practices. Second, the person then identifies as a member of that culture dependent on their rank within that community. Third, they develop relationships such as immediate family, close friends, coworkers, and neighbors.

Race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society. The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. By the 17th century, the term began to refer to physical (phenotypical) traits, and then later to national affiliations. Modern science regards race as a social construct, an identity which is assigned based on rules made by society. While partly based on physical similarities within groups, race does not have an inherent physical or biological meaning. The concept of race is foundational to racism, the belief that humans can be divided based on the superiority of one race over another.

Social conceptions and groupings of races have varied over time, often involving folk taxonomies that define essential types of individuals based on perceived traits. Modern scientists consider such biological essentialism obsolete, and generally discourage racial explanations for collective differentiation in both physical and behavioral traits.

This is a demography of the population of Peru including population density, ethnicity, religious affiliations and other aspects of the population.

Peru is a multiethnic country, which means that it is home to people of many different historical backgrounds. Therefore, it is a multicultural country as well. Since it is a multiethnic society, Peruvian people usually treat their nationality as a citizenship instead of an ethnicity. The Peruvian census does not contain information about ethnicity so only rough estimates are available.

Immigration is the international movement of people to a destination country of which they are not usual residents or where they do not possess nationality in order to settle as permanent residents. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however.

Economically, research suggests that migration can be beneficial both to the receiving and sending countries.The academic literature provides mixed findings for the relationship between immigration and crime worldwide. Research shows that country of origin matters for speed and depth of immigrant assimilation, but that there is considerable assimilation overall for both first- and second-generation immigrants.
