Also, the NAP/AP ratio of 0.29 appears abnormally low in comparison to other countries in West Africa with a comparable level of urbanisation. Therefore, the agricultural population appears to be overestimated. This is also appears highly improbable given that over the same period the level of urbanisation increased from 12 to 30% (U/R ratio from 0.14 in 1980 to 0.43 in 2010).
