Abstract
Based on the CFPS micro database, the influence direction and degree of the number of brothers and sisters on the income of the sample after adulthood were analyzed, and the heterogeneity between urban and rural areas, between men and women, different marital status and different birth years was analyzed. Studies have shown that the effect of the number of brothers and sisters on the income level after adulthood is significantly negative, that is, with the increase of the number of brothers and sisters owned by individuals, the income level of individuals after adulthood will decrease significantly, and the personal income level will fall by about 1663 yuan per year. The effect of the number of siblings on individual income level is significantly different between urban and rural areas and between samples of different birth years, as follows: for each additional sibling, the reduction of income level in urban areas is 972 yuan more than that in rural areas; the reduction of income level born before the implementation of the one child policy is 1067 yuan more than the after ones. This paper does not find that the influence of the number of brothers and sisters on personal income level is significantly different between men and women and between different marital states. The effect of the number of brothers and sisters on the level of personal income is that more brothers and sisters occupy family resources, reduce the education level of individuals, and disperse the care of parents, which makes the personal health condition worse.
