Figure 1: Geographical distribution of the top computer scientists (per million citizens).

In this work, we show that the ranking of a country changes significantly when we take into consideration its scientific personnel that has migrated abroad (i.e., brain-drain). Given that immigrant scientists are considered recoverable assets who can always return home, we believe that governments, businesses and trusts should anticipate immigrant scholars when deciding their scientific priorities, optimizing their research allocations, reorienting their research support, or augmenting research productivity.
