Income is an indicator and one of measurements used in the studies of poverty. Poverty in rural areas covers deep disparities according to social characteristics' (gender, education, occupation…) of the household head. This work aims to contribute to the studies on the poverty dynamics in rural area. Its main goal is to analyze the variability of incomes according to social profile of the households head in rural area in Katanga. Methodologically, 123 households taken in a random way were surveyed in 3 villages of Kipushi namely Kanyameshi, Makwatsha and Mimbulu. Five types of households are identified according to their professions (farmers 54%, craftsmen 11%, tradesmen farmers 18%, civil servants 5%, and farm labourers 12%). There are the agri tradesmen who earn more income (1320$) per year and 25% of the farmers, of the farm labourers, civil servants and the craftsmen realize nearly similar incomes. The marital status did not influence the income but the widowers have low income (703$) per year and 25% of them do not reach 465. 6$.As for the education, a significant difference is observed between the levels (p=0,011).If the academics have higher incomes followed by the illiterates, however, 25% of the latter have less of 450$ per year. Being given that the rural incomes seem to be fluctuating and liable to several risks, to increase them surely, these results plead for a rural development which passes first of all by an agricultural development, sector of more opportunities.
