While the bureau does not categorize income into subjective classes like lower-income, middle-class, or upper-class, they instead divide the population into five quintiles, ensuring that each quintile represents nearly the same number of households. This classification allows us to analyze income levels across a spectrum from the lowest to the highest income groups.
