Définition
Wage income corresponds to the sum of all the wages, net after all social contributions, including the general social contribution (CSG) and the social debt repayment contribution (CRDS) received by a person in a given year.
More precisely, there is a move from the hourly wage to the daily wage taking account of the amount of working time, and then to the annual wage income by multiplying the daily wage by the number of days paid during the year. By definition, the wage income does not integrate income from any non-salaried activities from which the wage-earner may benefit (for example, the case of a doctor practising both as a salaried employee in the hospital and having a private practice), nor any transfer income, even that determined by the activity (such as an employment premium) or insurance type income (such as unemployment benefits).
To go from the wage income of a person to the disposable income of a household, all the income of the various members of the household must be aggregated (including the income from any non-salaried activity and the income from assets) and all social transfers (statutory minimum, family allowances, housing benefits) after levies (such as income tax) must be counted.
