5. THESIM Towards Harmonised European Statistics on International Migration Consequences for interpretation of the figures –Not possible to follow the progress of cohort throughout the process –Not possible to know how many people are awaiting a decision, what happens following a negative decision Project financed by the 6th Framework Research Programme of the European Union

6. THESIM Towards Harmonised European Statistics on International Migration Flow statistics – immigration and emigration –Hundreds of sources - often different for immigration, emigration, nationals, non- nationals –Censuses, surveys, border counts, registration systems –Emigration is always under-counted NB do not calculate net migration as the difference between immigration and emigration figures – because of the undercount and the different sources. Project financed by the 6th Framework Research Programme of the European Union

7. THESIM Towards Harmonised European Statistics on International Migration Immigration Common problems to check –Are nationals (citizens) included in the flows? –Does the data source (eg work permits, visas) include only one group of migrants? –Is the figure an estimate ? Project financed by the 6th Framework Research Programme of the European Union
