Small area estimates (SAE) of food poverty and under nutrition in Nepal are produced at ilaka level by combining survey data with auxiliary data derived from the 2011 National Population and Housing Census (NPHC 2011). A model for predicting log average per capita household food expenditure is estimated from the 2010/11 Nepal Living Standards Survey III (NLSS-III) based on the Central Bureau of Statistics (CBS) calculation of food expenditure in each of the households sampled in the NLSS. The model is applied to household-level census data to estimate food poverty prevalence, gap and severity. CBS have used NLSS-III to derive estimates of caloric intake in the form of kilocalories consumed for each sampled household; these were converted to per-adult-equivalent (pae) values and a survey based model for kilocalorie consumption pae is also applied to household-level census data to predict kilocalorie consumption pae for each household; when compared with a standard adult kilocalorie requirement this is used to estimate low kilocalorie intake at ilaka level. Models for predicting standardized height-for-age, weight-for-age and weight-for-height of children under five are estimated from the 2011 Nepal Demographic and Health Survey (NDHS 2011); this is applied to child-level census data to estimate the prevalence of stunting, underweight and wasting. Prevalence of diarrhoea in children under five over a two-week period, as reported in NDHS 2011, is modelled and used to estimate diarrhoea prevalence at ilaka level. The small area estimation procedure used in this study does not produce direct measures of food poverty, caloric intake or child under nutrition at the local level.
Rather the procedure applied here is able to estimate welfare outcomes based on a statistical model estimated in the relevant household survey. These estimates of wellbeing are measured with error, and the degree of imprecision will vary as a function of a wide variety of factors, most notably the degree of disaggregation at which indicators of wellbeing are being estimated. In this study it was found that estimates at the level of an ilaka which comprises on average around 5500 households are generally reasonably precise. Estimates at Village Development Committee (VDC) or ward level are less precise.
Comparisons at higher levels (region, belt, urban/ rural) are made with the direct estimates derived from the survey data alone. The relationship between the various indicators, food poverty, low kilocalorie intake, child under nutrition and diarrhoea prevalence, is also examined.
The focus of this report strongly reflects the food security, nutrition, and child health interests and concerns of the sponsors of the study, which are the World Food Programme, UNICEF, and the World Bank.
