What is Social Class Influence?
Social class is a relatively permanent and ordered division of society whose members share similar values, interests, and behavior. The standard US measure (Gilbert-Kahl, Coleman-Rainwater) divides society into upper, middle, working, and lower classes, with sub-divisions. Class is a function of multiple variables — income, education, occupation, residence, family background — not income alone. Class predicts brand choice in many categories: educated middle-class buyers favor public radio, NPR-sponsoring brands, and Whole Foods; working-class buyers may share similar income but choose Country Music Television, Walmart, and beer. Marketers need both demographics and class to segment effectively in mature markets.
How Social Class Influence actually works
The framework breaks down into the following moving parts. Knowing what each piece is — and what it is not — is what separates a B-grade answer from an A-grade answer in a written assignment.
- Multi-variable measure — income, education, occupation, residence, family background
- Class shapes media consumption, store preference, brand affinity
- Class is more stable than income — a teacher and a plumber may earn similar income but consume differently
- Cross-class purchases (luxury aspiration, downscale slumming) create complexity
- Marketers segment by class for status-relevant categories
A worked example: Whole Foods vs Walmart
Whole Foods and Walmart serve buyers with overlapping income distributions but very different social classes. Whole Foods customers — disproportionately upper-middle and middle class with high education — value organic, sustainability, and the experience of shopping. Walmart customers — disproportionately working class — value price, convenience, and one-stop assortment. Both customer bases include $75k–$100k household incomes, but the class identification produces opposite shopping behaviors. Trying to merge them ("Whole Foods 365" stores in working-class neighborhoods) has consistently underperformed.
Don't lose marks for these
- Treating income as a proxy for class
- Ignoring class signals like education and occupation
- Stereotyping class — within-class variance is large
How to use this on the exam
Score-maximizing moves
- Distinguish class from income
- Cite Gilbert-Kahl or Coleman-Rainwater
- Apply class to a brand-choice example
When to use Social Class Influence (and when not to)
Use Social Class Influence when your assignment asks you to analyze, structure, or recommend — and when you have at least two data points to populate every cell of the framework. Skip it when the question is asking for a numerical answer or a single recommendation, since Social Class Influence is a structuring tool, not a calculator.
