Abstract
Since the seminal work of Sen, poverty has been recognized as a multidimensional phenomenon. The recent availability of relevant databases renewed the interest in this approach. This paper estimates multidimensional poverty among women in fourteen Sub-Saharan African countries using the Alkire and Foster multidimensional poverty measures, whose identification method is based on a counting approach. Four dimensions are considered: assets, health, schooling and empowerment. The results show important differences in poverty among the countries of the sample. The multidimensional poverty estimates are compared with some alternative measures such as the Human Development Index, income poverty, asset poverty and the Gender-related Development Index. It is found that including additional dimensions into the analysis leads to country rankings different from those obtained with the mentioned four measures. Decompositions by geographical area and dimension indicate that rural areas are significantly poorer than urban ones and that a lack of schooling is, in general, the highest contributor to poverty. The paper also conducts robustness and sensitivity analyses of the multidimensional estimates with respect to the number of dimensions in which deprivation is required in order to be considered poor, as well as to the poverty lines within each dimension. Several cases of dominance between countries are found in the first robustness test.

Notes
For example, the demography and health surveys (DHS) in Africa.
The dominance analysis here comes down to a simple one-dimensional dominance since all dimensions are aggregated in a vector c of deprivation counts.
With composite indicators, a third kind of robustness could be defined through the weights assigned to each dimension. Foster et al. (2009) examine such a variable-weight robustness criterion where a comparison is considered as robust if the ranking is not reversed at any weight vector within a given set. This type of robustness is not discussed here.
Here we ignore health deprivation that could derive from obesity.
Such estimates are available upon request to the author.
By definition, H ≥ M 0 > M 1 for all k. M 0 is derived from H by multiplying the latter by the average deprivation share. Thus, unless all poor are deprived in all dimensions for some k, in which case M 0 = H for this k, M 0 will be always lower than H. M 1 is computed by multiplying M 0 by the average poverty gap.
Asset poverty is estimated from the current method by considering only the eight indicators of Assets. Each indicator is weighted to 1 and the poverty measured by M 0 for k = 4.
Since 2010, the human development report replaced the Gender-related Development Index (GDI) by a different gender index named gender inequality index (GII).
