Consumer behavior involves the various stages a consumer goes through when purchasing goods or services. Understanding consumer behavior is essential for marketing success as consumers are increasingly value-conscious. Globally, consumers are worried about job stability but many feel secure in North America and China. While some consumers are loyal to favorite brands if prices are reasonable, others proactively search for savings, selectively splurge in some categories, and shop across channels. Key factors influencing consumer behavior include culture, subculture, social groups, personal characteristics, psychological aspects, and marketing activities. Household spending varies globally with countries spending more on healthcare, housing, food, transportation, or education depending on their needs and priorities.
