The CFSVA process generates a document that describes the food security status of various segments of a population over various parts of a country or region, analyses the underlying causes of vulnerability, and recommends appropriate interventions to deal with the problems. CFSVAs are undertaken in all crisis-prone food-insecure countries. The shelf life of CFSVAs is determined by the indicators being collected and reported. In most situations, CFSVA findings are valid for three to five years, unless there are drastic food security changes in the meantime.
The 2010 CFSVA is based on a nationally representative sample survey designed to provide information on food security and vulnerability in Sierra Leone. It is the first survey of this type carried out in both rural and urban areas. The Vulnerability Analysis and Mapping surveys of 2003, 2005 and 2007 were limited to only rural areas.
The objectives of the Sierra Leone CFSVA are:
- To produce reliable baseline data in a rapidly changing post-war context that needs regular situation monitoring
- To compare the food security status in rural versus urban areas following the rise in food prices
- To identify districts and livelihoods most affected by poverty and food insecurity
- To produce an updated reference document for agencies and institutions working in the area of food security in Sierra Leone.
Kind of Data
Sample survey data [ssd]
Unit of Analysis
- HOUSEHOLD: Demographic composition, education, migration, assets, access to credit, agricultural activities, sources of income, household expenditures, sources of food and foods consumed in the past week, shocks experienced and coping strategies, a health and nutrition module for children under five and their mothers/caretakers.
- COMMUNITY: Health, road infrastructure, health issues and access to education facilities.
The survey covered all household heads and women (with anthropometric measurements taken on both women 15-49 years of age and children 0-59 months old) in each sampled household.
A household is defined as a person or a group of persons related or unrelated, living together or not, making common cooking arrangements and under the authority of the same household head.

The CFSVA was designed to be representative for urban and rural analysis, by district and by the newly developed livelihood zones created by FEWSNET. A two-stage stratified cluster sample design was applied in the CFSVA. The strata of investigation are the 13 districts (with the Western Area is split into three separate strata) and ten livelihood zones. Livelihood zones have been defined by collaborative efforts led by FEWSNET, the Government of Sierra Leone and other partners including WFP in May of 2010. The first stage of the two-stage cluster design was the selection of Enumeration Areas (EAs) in each stratum using PPS (Probability Proportional to Size). The second stage is the random selection of households within each selected EA. The EAs were selected from a list of Enumeration Areas provided by Statistics Sierra Leone (SSL) which is based on the 2004 Population and Housing Census. Households in each EA have been selected after a listing exercise done by the enumeration team during the actual data collection. In total, there are 34 strata in the sample design. This is based upon urban and rural representative data for each district, the three strata from the Western Area, and the 10 livelihood zones. Therefore the overall sample size of Sierra Leone 2010 CFSVA is 4,896 households in 408 communities.
In collaboration with Statistics Sierra Leone, weights were calculated based upon the most up to date population statistics available and areas applied during the analysis.

Data Collection Mode
Data Collection Notes
Enumeration teams were composed of one supervisor and four enumerators. Sixteen enumeration teams were sent each in a district except for Koinadugu which had two teams to ensure the different livelihood zones were captured and in the Western Area where three teams were sent to cover each of the unique strata there. A team of supervisors comprised of staff from the Ministry of Agriculture Forestry and Food Security (MAFFS), SSL and WFP. These teams worked with enumeration teams to ensure data quality during the collection period.
Households were asked various questions regarding the demographic composition of the home, education, migration, assets, access to credit, various aspects of agricultural activities, sources of income, household expenditures, sources of food and foods consumed in the past week, shocks experienced and coping strategies. In addition, a health and nutrition module was included for children under five and their mothers/caretakers.
Community questionnaire was also used in each of the enumeration areas. This questionnaire captured information about the community on topics such as health and road infrastructure, community health issues and access to education facilities. The data from this module was used to contextualize the communities surveyed for descriptive purposes.
