All peoples shall have the right to their economic, social and cultural development with due regard to their freedom and identity and in the equal enjoyment of the common heritage of mankind. 2. States shall have the duty, individually or collectively, to ensure the exercise of the right to development. According to the data drawn from the recent CSLP Review, a survey carried out within the households in 2006, the rate of poverty is estimated at 67% at the national level, of which 69% is in the rural areas and 34% in the urban areas. These estimates are based on a poverty threshold per equivalent adult of 627Fbu/day in the urban areas and of 525Fbu/day in the rural areas. The results of this same survey provide an insight of the level of poverty prevailing in each of the country’s Provinces thereby leading to a better knowledge of the priority regions requiring redefinition and the improved targeting of the programmes. The categorization of the Provinces according to the enormity of the population strength living below the poverty threshold is indicated in the following graph. 22.1.
