There are two good reasons for taking another look at the analysis of migration figures from the Spanish statistics. Firstly, because since 2008 the country has been undergoing a profound economic crisis and the extent to which it is impacting on the outflows of foreigners from Spain is unknown. And, secondly, because the INE has just made new sources derived from innovative statistical procedures available. The work has focused on analyzing the international migration figures of these sources and uses them to evaluate the degree of underestimation of the international migration outflows in the traditional Residential Variation Statistics. Furthermore, two additional conclusions have been reached in the paper that, from the point of view of the quality of the new statistical sources, should be reflected upon.
