The literature generally finds that lower air quality has been an important determinantof migration.  This study builds a migration model employing annual data from 2010to  2019  for  the  most  polluted  ten  countries  to  test  the  validity  of  migration  causedby air pollution through PM2.5 concentration.  The Poisson Pseudo Maximum Likeli-hood method results show that air pollution is one of the most significant determinantsof  migration  from  the  most  polluted  countries.  Moreover,  the  low  income  level  alsopushes people to migrate more from their origin regions than richer ones.  The studyprovides some policy recommendations for policy-makers in the countries where peo-ple  breathe  the  most  polluted  air:   (i)  governments  should  follow  growth-promotingeconomic  policies;  (ii)  environment-friendly  production  techniques  should  be  imple-mented  to  prevent  worsening  environmental  quality;  (iii)  climate-induced  mass  mi-gration should be considered while making security policy arrangements.
