This was the third UNHCR SENS to be conducted in the camps since the Ivorian refugee emergency in 2010 in Liberia; the first was in 2012 and second in 2013.
The UNHCR Standardized Expanded Nutrition Surveys (SENS) provide regular nutrition data that plays a key role in delivering effective and timely interventions to ensure good nutritional outcomes among populations affected by forced displacement. This survey was conducted in Bahn, PTP and Little Wlebo camps, which are located in Maryland, Grand Gedeh and Nimba counties lying along the border of Liberia and Côte d'Ivoire. The three camps were hosting close to 29,000 Ivorian refugees including approximately 5,000 children aged below five years. The survey, which was organized by UNHCR in close collaboration with World Food Programme (WFP), UN Childrens Fund (UNICEF), CARE, African Humanitarian Action (AHA) and Country Health Teams / Ministry of Health and Social Welfare of the Republic of Liberia, was conducted from 7th April to 2nd May 2015. This was the third SENS to be conducted in the camps since the Ivorian refugee emergency in 2010 in Liberia; the first was in 2012 and the second in 2013.

The SENS covered the following topics:

- Children 6-59 months: prevalence of acute malnutrition, underweight, stunting and anaemia, coverage of vit A supplementation, and prevalence of diarrhea
- Chidlren 9-59 months: coverage of measles vaccination
- Women 15-49 years: prevalence of anaemia
- Households: food security, mosquito net coverage and water, sanitation and hygiene information

A systematic sampling technique without list was applied in this survey. UNHCR SENS guidelines for refugee populations (version2, 2013) and the Standardized Monitoring and Assessment of Relief and Transitions (SMART) methodology version 2 released on 11th January 2015 was used to plan the required sample size. ENA for SMART software was used for calculation of the minimum sample size required for each camp. Despite that weighted prevalence of GAM was 2.7% in the 2013 survey, the hit of EVD in Liberia was presumed to have negatively affected nutritional status of under-fives and hence, expected prevalence of acute malnutrition was elevated and set at 6% in all camps. During sample size calculation precision of 3% was desired, non-response and absentees was set at 10% bearing in mind of EVD outbreak in Liberia. Average household size and percentage of under-fives was considered from individual camp based on the 2013 nutrition survey. Correction for small population size was applied during sample size calculation given the population of under-fives is <10,000.
Data are weighted by refugee camp and target population: children 0-59 months, women 15-49 years and households. Design weights included in datasets (see survey_weight).
