The first methodology is a 7-day recall period, the second one is a usual month, and the third one is a 7-day diary. The paper finds that there is a difference in the distribution of welfare between, on the one hand, the two first methodologies (7-day recall and a usual month, which give results close to each other) and, on the other hand, the 7-day diary method. When considering annual per capita consumption, the 7-day diary lags the 7-day recall by 28 percent. This gap is not only at the mean of the distribution, it has been found at any level. These differences lead to differences in poverty and inequality measures even when alternate poverty lines are used. This study underscores the problem that many developing countries face when it comes to monitoring poverty indicators over time where different methodologies have been used over the years.en-USCC BY 3.0 IGOABSOLUTE POVERTYACCESS TO INFRASTRUCTUREAGRICULTURAL ACTIVITIESAGRICULTURAL SEASONAGRICULTUREAPPLESASSESSING WELFAREBREADCALORIE INTAKECALORIES PER DAYCALORIES PER PERSONCALORIES PER PERSON PER DAYCASE STUDYCASH EXPENDITURESCEREALSCOMPARING POVERTYCONSISTENT POVERTYCONSUMER PREFERENCECONSUMPTION AGGREGATECONSUMPTION DISTRIBUTIONCONSUMPTION PER CAPITACONSUMPTION PRICECOOKINGDAIRYDATESDECLINE IN POVERTYDEVELOPING COUNTRIESDEVELOPMENT ISSUESDEVELOPMENT RESEARCHECONOMIC GROWTHEGGSEXPENDITURE DATAEXPENDITURE INFORMATIONFAMILY MEMBERSFOOD COMPONENTSFOOD CONSUMPTIONFOOD CONSUMPTION DATAFOOD CONSUMPTION EXPENDITUREFOOD CONSUMPTION INFORMATIONFOOD EXPENDITUREFOOD EXPENDITURESFOOD ITEMSFOOD PRODUCTFOOD SECURITYHEALTH EXPENDITURESHOUSEHOLD CHARACTERISTICSHOUSEHOLD COMPOSITIONHOUSEHOLD CONSUMPTIONHOUSEHOLD DEMOGRAPHICSHOUSEHOLD EXPENDITUREHOUSEHOLD EXPENDITURESHOUSEHOLD HEADSHOUSEHOLD MEMBERSHOUSEHOLD SIZEHOUSEHOLD SURVEYHOUSEHOLD SURVEYSHOUSINGILLITERACYIMPACT ON POVERTYINCOMEINEQUALITYIRRIGATIONLIVING STANDARDSLIVING STANDARDS MEASUREMENTMAIZEMEASURED POVERTYMEASURING POVERTYMEATMILKMONITORING POVERTYMONTHLY EXPENDITURENATIONAL POVERTYNATIONAL POVERTY LINENON-FOOD COMPONENTNON-FOOD COMPONENTSNON-FOOD CONSUMPTIONNON-FOOD EXPENDITURENON-FOOD ITEMSNONFOOD COMPONENTNUTRITIONORANGESPEANUTSPER CAPITA CONSUMPTIONPOLICY RESEARCHPOORPOOR PEOPLEPOVERTY ASSESSMENTPOVERTY COMPARISONPOVERTY COMPARISONSPOVERTY ESTIMATESPOVERTY GAPPOVERTY INDICATORSPOVERTY LEVELPOVERTY LEVELSPOVERTY LINEPOVERTY LINESPOVERTY MEASUREMENTPOVERTY MEASURESPRICE INFORMATIONRICERURALRURAL AREASRURAL POPULATIONRURAL POPULATIONSSQUARED POVERTY GAPSTANDARD ERRORSSURVIVAL STRATEGIESTARGETINGUNDERSTANDING OF POVERTYURBAN AREASWELFARE DISTRIBUTIONWELFARE INDICATORWELFARE INDICATORSWELFARE LEVELWELFARE MEASURE10.1596/1813-9450-7090
