Labor market data is the collection and analysis of information about the supply and demand of labor in different occupations, industries, and locations. Labor market data can provide information on various aspects of employment, such as wages, hours, skills, education, training, and projections. Among the four options, only earnings are directly related to labor market data, as they reflect the compensation of workers for their labor. Accommodations, transportation, and retirement benefits are not provided by labor market data, as they are not directly related to the value of labor, but rather to the living conditions, mobility, and future security of workers.
