What aspect of market segmentation focuses on consumers' income levels?

The aspect of market segmentation that focuses on consumers' income levels is demographic segmentation. This type of segmentation divides the market based on specific characteristics such as age, gender, family size, income, occupation, education, and nationality.

By categorizing consumers according to their income levels, businesses can tailor their products, services, and marketing strategies to meet the specific needs and purchasing power of different income groups. For instance, luxury brands might target high-income consumers while discount retailers may focus on those with lower income levels, ensuring that their offerings align with the financial capabilities of their target audience. This helps businesses effectively position themselves in the market and optimize their marketing efforts based on the economic profiles of potential customers.
