Social stratification is a kind of social differentiation whereby a society groups people into socioeconomic strata, based upon their occupation and income, wealth and social status, or derived power (social and political).
 As such, stratification is the relative social position of persons within a social group, category, geographic region, or social unit.
 In modern Western societies, social stratification typically is distinguished as three social classes: (i) the upper class, (ii) the middle class, and (iii) the lower class; in turn, each class can be subdivided into strata, e.g. the upper-stratum, the middle-stratum, and the lower stratum.
 Moreover, a social stratum can be formed upon the bases of kinship, clan, tribe or caste, or all four.
Research in Social Stratification and Mobility is an annual peer-reviewed academic journal covering research on social stratification and inequality.

The three-component theory of stratification, more widely known as Weberian stratification or the three class system, was developed by German sociologist Max Weber with class, status and power as distinct ideal types.
 Weber developed a multidimensional approach to social stratification that reflects the interplay among wealth, prestige and power.
A society is a group of people involved in persistent social interaction, or a large social group sharing the same geographical or social territory, typically subject to the same political authority and dominant cultural expectations.
 Societies are characterized by patterns of relationships (social relations) between individuals who share a distinctive culture and institutions; a given society may be described as the sum total of such relationships among its constituent of members.
 In the social sciences, a larger society often evinces stratification or dominance patterns in subgroups.
Social inhibition is a conscious or subconscious avoidance of a situation or social interaction.
 With a high level of social inhibition, situations are avoided because of the possibility of others disapproving of their feelings or expressions.
 Social inhibition is related to behavior, appearance, social interactions, or a subject matter for discussion.
 Related processes that deal with social inhibition are social evaluation concerns, anxiety in social interaction, social avoidance, and withdrawal.
 Also related are components such as cognitive brain patterns, anxious apprehension during social interactions, and internalizing problems.
 It also describes those who suppress anger, restrict social behavior, withdraw in the face of novelty, and have a long latency to interact with strangers.
 Individuals can also have a low level of social inhibition, but certain situations may generally cause people to be more or less inhibited.
 Social inhibition can be reduced by the use of drugs including alcohol.
 Major signs of social inhibition in children are cessation of play, long latencies to approaching the unfamiliar person, signs of fear and negative affect, and security seeking.
 Also in high level cases of social inhibition, other social disorders can emerge through development, such as social anxiety disorder and social phobia.
Class stratification is a form of social stratification in which a society tends to divide into separate classes whose members have different access to resources and power.
 An economic and cultural rift usually exists between different classes.
 People are usually born into their class, though social mobility allows for some individuals to attain a higher-level class or fall to a lower-level one.

K’axob is an archaeological site of the Maya civilization located in Belize.
 It was occupied from about 800 B.C. to A.D. 900.
 The site is located in northern Belize in the wetlands of Pulltrouser Swamp in proximity to the Sibun River Valley in central Belize.
 Research has shown that K’axob was occupied from the Late Preclassic Period to the Early Postclassic Period.
 This period in time and the site is characterized by specific ceramic types as well as agriculture and an increase in social stratification.
 K’axob is a village site centered on two pyramid plazas and later grew in size during the Early Classic Period to the Late Classic Period.
 The site includes a number of household, mounds and plazas.
 K’axob is mostly based on residential and household living but also has some ritualistic aspects.
 Many of the structures at the site show evidence of household dwellings as well as ritual purposes.
 There are many burials at the site that illustrate the ritualistic aspects and social stratification at K’axob.
 Many of the individuals, some more than others, were interned with beads made of shell as well as ceramic vessels, demonstrating this potential social stratification.
 The pottery vessels recovered from the site demonstrates regularity in the production of pottery.
 The most prominent type of ceramic vessels recovered from the site were ‘serving bowls,’ with a tripodal base, and were present during the Early Classic Period.
 There is also evidence of specialized areas for pottery production.
 There are middens at the site that yielded a great deal of pottery sherds and are associated with structures that are believed to be kilns as well as with tools similar to modern pottery making tools.
 There is also some evidence of stone tool production at the site.
 The most common stone tool recovered from the site is a chert oval biface and is associated with agriculture and thought to have been used for weeding and hoeing.
Caste is a form of social stratification characterized by endogamy, hereditary transmission of a lifestyle which often includes an occupation, status in a hierarchy, and customary social interaction and exclusion.
 Although caste systems exist in various regions, its paradigmatic ethnographic example is the division of Indian society into rigid social groups, with roots in India's ancient history and persisting until today.
 However, the economic significance of the caste system in India has been declining as a result of urbanization and affirmative action programs.
 A subject of much scholarship by sociologists and anthropologists, the Indian caste system is sometimes used as an analogical basis for the study of caste-like social divisions existing outside India.
 The term is also applied to non-human populations like ants and bees.
