Poverty line
Poverty in this report is measured using estimated consumption expenditures. The poverty line is a threshold below which people are deemed poor. Household expenditure in Kenya averages KSh 3,002.8 per adult equivalent per month nationally. However, there are differences between urban and rural areas, counties and constituencies. Household expenditures per adult equivalent per month are KSh 1,962.10 in rural areas compared with KSh 4,690.6 in urban areas. In 2005/07, the poverty line was estimated at KSh 1,562 and KSh 2,913 per adult equivalent per month for rural and urban households respectively. Nationally, 45.2 percent of the population lives below the poverty line (2009 estimates), down from 46 percent in 2005/06.
At county level, there are significant inequalities in poverty. The proportion of individuals below the poverty line in Turkana (87.5 percent), Mandera (85.8 percent) and Wajir (84.2 percent) is four times that of Nairobi, which has the lowest poverty at 21.8 percent (see Table 3.3), and almost double that of Laikipia (47.9 percent), the median county. The national inequalities in poverty across counties are depicted in Figure 3.1, where the incidence of poverty is higher in the northern and coastal parts of the country and significantly lower in others especially in Nairobi and the central parts of the country.
These differences are more pronounced at constituency level (Table 3.3) whereby the proportion of the population below the poverty line in the poorest constituency (Turkana East) with 93.1 percent of its population living below the poverty line is nine times greater than the least poor constituency (Embakasi West) where only 10.3 percent of the population live below the poverty line. In total, 25 counties and 148 constituencies have more than 45.2% of their populations below the national poverty line.
