Objectives and methodology

• The main objective of this research is to construct a composite indicator of multidimensional poverty using basic needs. That will also make it possible to explore the link between monetary and non-monetary poverty.

• We use Multiple Correspondence Analysis (MCA) to construct the Composite Poverty Indicator (CPI). MCA is a method that enables data reduction while preserving essential information.

4

Objectives Methodology

• The dimensions used in the building of this composite indicator are related to education, health, drinking water, food, housing, energy, communication, housing equipments and comfort elements.

• For a given household, the value of the CPI is a linear combination of binary indicators describing its well-being with weights resulting from MCA as indicated by the following formula:

5

• The first factorial axis describes well-being; it opposes poor to non-poor.

6

• Typology of poverty• Households are not all affected by the same type of poverty. The

forms of non-monetary poverty which are the most prevalent are related to vulnerability of human existence (low human capital, difficult living conditions), lack of infrastructures, and elements of comfort and housing.

RESULTS

• Relationship between Composite Poverty Indicator (CPI) and household characteristics

• Position of rural and urban areas on the CPI : the following graph indicates that rural area is located in the poverty zone whereas urban area is located in the non-poor zone.

8

RESULTS

• Relationship between CPI and sex of household chief:• On this graph, male household heads are located on the poverty zone

while female household heads are located on the non-poor side.

9

RESULTS

• Composite poverty indicator and household size• This graph indicates that poverty increases with household size

10

RESULTS

Composite Indicator and activities of the household head:

The graph indicates that farmers are poorer than other people.

11

RESULTS

• Composite Indicator and marital status• Polygamists are poorer than people of other marital status.

12

RESULTS

• Link between monetary and non monetary poverty • The following graph indicates that a positive link exists between

monetary and multidimensional poverty

• The correlation coefficient between the composite indicator and the per capita expenditure per equivalent adult is 0.47 and the correlation coefficient of the ranks is 0.60

13

RESULTS

• Incidence of multidimensional poverty

• We compute the CPI of a household just meeting basic needs. We interpret this value as a poverty line. In our case it is 0.088

• All in all, the obtained results are similar to those of the monetary approach but with some divergences. The proportion of poor is 60% and the poorest groups are related to living in a rural area, being farmers, living in large families …

• The following table indicates that for the two forms of poverty (monetary and non-monetary), rural area is affected more than the urban one.

• Population in the rural area are affected more by the multidimensional poverty, whereas those in the urban area are especially affected by monetary poverty

RESULTS

• Prevalence of “double poverty”• Double poverty is about households who are affected by the two forms

of poverty, (monetary and non-monetary). The results of the study indicate that double poverty affects especially the poorest group (rural area, farmers, large family ... ).

• The following table indicates that population in rural area are particularly affected by the two forms of poverty (59.6%) whereas population who are not poor according to the two concepts of poverty are located in the urban area (55.8%).

• The proportion of population who are poor according to multidimensional poverty but non-poor for the monetary poverty is particularly high in rural area (32.7%).

• The proportion of population who are non-poor according to multidimensional poverty but poor for the monetary poverty is particularly high in urban area (21.19%). Urban area is especially affected by monetary poverty despite of the existence of infrastructure, human capital and comfortable housing. These results suggest the imperfection of markets.

Conclusion

• From Multiple Correspondence Analysis, we constructed a composite indicator of multidimensional poverty. This composite indicator orders households according to their well-being.

• The results indicate the existence of three main forms of non-monetary poverty: vulnerability of the human existence, poverty in infrastructure, and poverty in “comfort”.

• The poorest groups are related to the rural zone, farmers, large family ...

• These same poorest groups are affected by double poverty (monetary and non-monetary). Those in the rural area are affected more by the multidimensional poverty, whereas those in the urban zone are especially affected by monetary poverty.

• Finally a clear positive link exists between multidimensional and monetary poverty.
