In a new data set of national poverty lines we find that a marked economic gradient only emerges when consumption per person is above about $2.00 a day at 2005 purchasing power parity. Below this, the average poverty line is $1.25, which we propose as the new international poverty line. Relative poverty appears to matter more to developing countries than has been thought. The authors' proposed schedule of relative poverty lines is bounded below by $1.25, and rises at a gradient of $1 in $3 when mean consumption is above $2.00 a day.CC BY 3.0 IGOABSOLUTE POVERTYABSOLUTE POVERTY LINEAGGREGATE POVERTYAID DONORSBASIC NEEDSBULLETINCALORIES PER PERSONCALORIES PER PERSON PER DAYCAPITAL CITYCONFLICTCONSUMER PRICE INDEXCONSUMPTION AGGREGATECONSUMPTION EXPENDITURECONSUMPTION PER CAPITACOUNTRY DATACOUNTRY LEVELCOUNTRY SPECIFICDATA QUALITYDENSITY FUNCTIONDEVELOPED COUNTRIESDEVELOPING COUNTRIESDEVELOPING COUNTRYDEVELOPING WORLDDEVELOPMENT REPORTDEVELOPMENT RESEARCHECONOMIC PERFORMANCEECONOMICSEMPIRICAL MODELEMPIRICAL RESULTSERROR TERMEXCHANGE RATEEXCHANGE RATESFIGHT AGAINST POVERTYFOOD BASKETFOOD BUNDLEFOOD COMPONENTSFOOD CONSUMPTIONFOOD NEEDSFOOD POVERTYFOOD POVERTY LINEFOOD SECURITYFOOD SHAREFUNCTIONAL FORMGLOBAL MARKETSGLOBAL POVERTYGOOD GOVERNANCEHOUSEHOLD BUDGETHOUSEHOLD CONSUMPTIONHOUSEHOLD INCOMESHOUSEHOLD SURVEYSHOUSINGINCOMEINCOME DISTRIBUTIONINCOME ELASTICITYINCOME INEQUALITYINCOME LEVELSINCOME POVERTYINDIVIDUAL WELFAREINTERNATIONAL POVERTY LINEINTERNATIONAL POVERTY LINESJOB CREATIONLABOR MARKETLEVELS OF CONSUMPTIONLIVING CONDITIONSLIVING STANDARDSLOCAL MARKETSLOW-INCOMELOW-INCOME COUNTRIESMEASUREMENT OF POVERTYMEASURING POVERTYMEATMICRO DATANATIONAL ACCOUNTSNATIONAL POVERTYNATIONAL POVERTY LINESPOLICY RESEARCHPOLICY RESEARCH WORKING PAPERPOORPOOR COUNTRIESPOOR PEOPLEPOOR PERSONPOPULATION AND DEVELOPMENTPOPULATION SHAREPOPULATION SIZEPOVERTY ASSESSMENTPOVERTY ASSESSMENTSPOVERTY COMPARISONSPOVERTY GAPPOVERTY LINEPOVERTY MEASUREPOVERTY MEASUREMENTPOVERTY MEASURESPOVERTY PROFILEPOVERTY PROFILESPOVERTY RATESPOVERTY REDUCTIONPOVERTY REDUCTION PROGRAMPOVERTY REDUCTION STRATEGYPOVERTY REDUCTION STRATEGY PAPERPOVERTY REDUCTION STRATEGY PAPERSPOVERTY STUDYPOVERTY UPDATEPREVAILING NOTIONSPRO-POORPRO-POOR GROWTHPROGRESSPUBLIC SECTORPURCHASING POWERPURCHASING POWER PARITYREDUCING POVERTYRICH COUNTRIESRISK SHARINGRURALRURAL AREASRURAL POPULATIONRURAL POVERTYRURAL POVERTY LINERURAL POVERTY LINESSCHOOLINGSIGNIFICANT CORRELATIONSOCIAL EQUITYSOCIAL JUSTICESOCIAL POLICYSOCIAL PROTECTIONSOCIAL SECTORSSTANDARD DEVIATIONSUBSISTENCETOTAL POVERTYTOTAL POVERTY LINETRINIDAD AND TOBAGOURBAN AREASURBAN CENTERSURBAN POVERTYURBAN POVERTY LINESURBANIZATIONVEGETABLESVULNERABILITYVULNERABILITY ASSESSMENTWorld Bank10.1596/1813-9450-4620
