How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to stratum is stratification.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Sociology

a layer of people occupying a similar position in a ranked social order, sharing similar wealth, status or power.

In sociology a stratum is a layer of people who occupy a similar position in a ranked social order, sharing broadly the same wealth, status, or power. Pitirim Sorokin's 1927 Social Mobility set out society as a set of such stacked layers and studied how individuals rise and fall between them, taking the layered picture from geology. Membership in a stratum is defined by shared economic, occupational, or prestige position rather than by any physical boundary. The referent is a rank within a human hierarchy, described by the resources and life chances its members share, not a bed of rock or a division drawn for a survey.[1]

Unit
One rank within a stratified society, defined by shared position
Recovery means
Not applicable
Measured by
Operationalised by income, occupation, education, and prestige scales that place people into ranked groups

Statistics

one of the mutually exclusive groups a population is split into before sampling, each sampled on its own.

In statistics a stratum is one of the mutually exclusive groups into which a population is split before sampling, so that each group can be sampled on its own. Jerzy Neyman's 1934 On the two different aspects of the representative method formalised stratified sampling and showed how dividing a population into strata and allocating the sample across them can lower the error of an estimate. A useful stratum is internally similar on the quantity of interest while differing from the other strata. The referent is a division of a population made by the researcher for sampling, defined by a grouping variable, not a rock bed in the ground or a rank of people in a society.[2]

Unit
One subgroup of a population set apart for separate sampling
Recovery means
Not applicable
Measured by
Defined by a stratifying variable, with sample size split across strata by proportional or optimal (Neyman) allocation
