What does lower middle class mean?

The term 'lower middle class' typically refers to a socioeconomic group that falls between the working class and the middle class. People in this group often have moderate incomes, may hold clerical, administrative, or low-level supervisory jobs, and may have some post-secondary education or vocational training. They generally have enough income to cover basic needs and some discretionary spending, but may face financial challenges with unexpected expenses. The exact definition can vary depending on country and economic context.
