Earnings from non-standard work tend to be more dispersed than earnings from standard jobs, as non-standard jobs are more heterogenous (Annex 4.A3, Table 4. A3.2): the factor dispersion (in terms of Gini coefficient) for NSW earnings is about 0.8, compared with 0.55 for SW earnings. In addition to being more unequally distributed, earnings from NSW are more concentrated in the households at the lower part of the income distribution, as the factor correlation between NSW earnings and total household income is low (on average about 0.33).
