Although the progress has been impressive, some basic challenges remain. This paper addresses some basic, yet fundamental, questions on identification of international migrants and how their various demographic, personal, and human capital characteristics are captured via different data sources. The critical issues are the construction of proper sampling frames in censuses, registers, and surveys and the design of questionnaires in household, labor market, and other relevant surveys. The paper discusses how these data sources can be used to answer policy questions in areas such as labor markets, education, or poverty. The focus is on how some of the existing shortcomings in availability, quality, and relevance of migration data can be overcome via improvements in data collection methods.en-USCC BY 3.0 IGOADULT MORTALITYAGEDAGINGARMED CONFLICTASYLUMASYLUM SEEKERSBENEFITS OF MIGRATIONBRAIN DRAINBRAIN-DRAINCAPITAL MOBILITYCAUSES OF MIGRATIONCENSUSESCHILD HEALTHCHILD LABORCITIZENCITIZENSCITIZENSHIPCIVIL CONFLICTCLIMATE CHANGECONTRACEPTIVE USECOUNTRIES OF ORIGINCOUNTRY OF DESTINATIONCOUNTRY OF ORIGINDEFORESTATIONDEPORTATIONDEVELOPING COUNTRIESDEVELOPMENT POLICIESDEVELOPMENT POLICYDIASPORADIETDIETSDISPLACEMENTDISSEMINATIONEARLY CHILDHOODEARTHQUAKEECONOMIC INTEGRATIONECONOMICSECONOMICS OF IMMIGRATIONEDUCATED MIGRANTSEDUCATIONAL ATTAINMENTEMIGRANTSEMIGRATIONENVIRONMENTAL CHANGEEXPATRIATESEXTERNALITIESFAMILIESFAMILY MEMBERSFAMILY REUNIFICATIONFARMSFERTILITYFOOD SECURITYFORCED MIGRATIONFOREIGN DIRECT INVESTMENTGENDER DIFFERENCESGLOBAL DEVELOPMENTGLOBAL POLICYHEALTH CAREHEALTH EXPENDITURESHEALTH OUTCOMESHOME COUNTRIESHOUSEHOLD LEVELHOUSEHOLD SURVEYSHUMAN CAPITALHUMAN MIGRATIONIMMIGRANTIMMIGRANTSIMMIGRATIONIMPACT OF MIGRATIONIMPORTANT POLICYINCOME DISTRIBUTIONINFANTINFRASTRUCTURE PROJECTSINTERNAL MIGRATIONINTERNATIONAL BORDERSINTERNATIONAL MIGRANTSINTERNATIONAL MIGRATIONINTERNATIONAL MIGRATION REVIEWINTERNATIONAL MOBILITYINTERNATIONAL TRADEJOB CREATIONJOB TRAININGLABOR FORCELABOR MARKETLABOR MARKETSLABOR SHORTAGESLABOR SUPPLYLABOUR MARKETLAWSLEGAL STATUSLIVING STANDARDSLOCAL AUTHORITIESLOTTERIESLOW-INCOME COUNTRIESMARITAL STATUSMIGRANTMIGRANT POPULATIONSMIGRANT WORKERSMIGRATIONMIGRATION BETWEEN COUNTRIESMIGRATION DATAMIGRATION FLOWSMIGRATION FOR EMPLOYMENTMIGRATION INDICATORSMIGRATION PATTERNSMIGRATION POLICIESMIGRATION PROCESSMIGRATION RATESMIGRATION STATISTICSMOTHERNATIONAL BORDERSNATIVE WORKERSNATURAL DISASTERNATURAL DISASTERSNATURAL RESOURCENATURAL RESOURCESNATURALIZATIONNUMBER OF HOUSEHOLDSNUMBER OF INTERNATIONAL MIGRANTSNUMBER OF MIGRANTSNURSINGNUTRITIONAL STATUSPARENTAL INVOLVEMENTPERMANENT RESIDENCEPOLICY DISCUSSIONSPOLICY MAKERSPOLICY RESEARCHPOLICY RESEARCH WORKING PAPERPOLITICAL OPPOSITIONPOPULATION AND DEVELOPMENTPOPULATION ASSOCIATIONPOPULATION CENSUSPOPULATION MIGRATIONPOTENTIAL MIGRANTSPROGRESSQUALITY OF EDUCATIONREFUGEEREFUGEESREMITTANCEREMITTANCESREPRODUCTIVE AGERESOURCE USERESPECTRETURN MIGRATIONRETURNEERETURNEESRURAL AREASRURAL DEVELOPMENTRURAL PRODUCTIVITYRURAL­URBAN MIGRATIONSCHOOL ATTENDANCESEASONAL MIGRATIONSIBLINGSSKILL LEVELSKILLED MIGRANTSSKILLED WORKERSSOCIAL AFFAIRSSOCIAL CAPITALSOCIAL GROUPSOCIAL NETWORKSSOCIAL SECURITYSOCIOECONOMIC PROCESSESSPOUSESTATUS OF REFUGEESTEMPORARY MIGRANTSTEMPORARY MIGRATIONTERTIARY EDUCATIONTRANSACTION COSTSUNDOCUMENTED MIGRANTSUNDOCUMENTED MIGRATIONUNEMPLOYMENTUNEMPLOYMENT LEVELSUNITED NATIONS HIGH COMMISSIONER FOR REFUGEESURBAN MIGRATIONURBANIZATIONVIOLENCEVISASWAGE RATESWAGESWARWARSWASTE10.1596/1813-9450-7082
