Goal of the data analysis The surveys are only significant and
representative at the local level However, they can be illustrative of the
regional dynamics and trends… The surveys combined with the regional
studies and chain analyses provide: a general description of local characteristics a justification of the choice of the selected
regions Information to respond to the program
hypotheses

Level 1: regional data breakdown* Main characteristic of the regional sample
Demography Size of the household in adult equivalent Dependency ratio
Human capital Education
Social capital Network index
Structure of economic activities % of HH
Global income Level, distribution and structure of income => which allows to test
the differences between regions Mean: income shares are calculated for each household, and then the mean
of the household shares of each type of income is calculated
* At the household level per region: mean, median, min/max, standard deviation
![Page 6: Analysis of the field work and the collected information of phase II Gorée, Senegal - June, 2008](https://reader035.vdocuments.site/reader035/viewer/2022062322/56814842550346895db55967/html5/thumbnails/6.jpg)
Level 2: explanation of the heterogeneity or homogeneity of the regional results
If the analysis of the global income at the regional level gives a high standard deviation
=> check of the heterogeneity at the local level (locality, community, village)
* mean, median, min/max, standard deviation

Level 3: Global income classes analysis
In order to compare the income structure and their characteristics among the 7 RS countries, we must split our sample into 5 equal rural households’ quintiles from the poorest to the richest
This way of calculating the quintiles [or deciles] is different from income distribution analysis (level 1)
