Jean Stoetzel : Age and income.
Income by age is approached cross-sectionally, on the basis of answers gathered in the course of a number of sample surveys, carried out by the French Institute of public opinion. Every respondent is shown a card with eight classes of income, from less than 250 F a month, to 4.000 F and over and requested to locate himself on it. The sample is national representative. The number of answers exceed 20.000 for six months. The study extend from 1967-1968 to mid-1972. The statistics considered are the median and the quartile ratio, since all distributions are log-normal. The range of the ageclasses is five years, from 20 to 70 and over. Findings. The variation of the income median is a second degree function of age, x, with a negative coefficient of x. The fitting of the law, computed by the least squares method, is quite good. The maximum of the income median, yielded by the value of x which makes the derivative equal zero, appears below the age of forty. From 1970 to the end of 1971, the age of the maximum has been decreasing to less than 34 years. It increased in 1972. The dispersion of the distribution of income by age is also a parabola, with a positive coefficient of x and a minimum in the vicinity of 30 years. Conclusion. The variation of income by age in France shows no plateau. Income goes up before the age of 40, then diminishes. Income dispersion increases in geometric progression with age, except for ages below 25. Source : Éditeur (via Persée) |
