Founded in 2001, the Migration Policy Institute (MPI) is an independent, nonpartisan think tank in Washington, D.C., dedicated to analysis of the movement of people worldwide. MPI provides analysis, development, and evaluation of migration and refugee policies at local, national, and international levels. It aims to meet the demand for pragmatic and thoughtful responses to the challenges and opportunities that large-scale migration, whether voluntary or forced, presents to communities and institutions in an increasingly integrated world.
The politically motivated smears against this site say more about those who would deny fact-based immigration discussion than it does about the site. This is a good, serious site.
MPI is a think tank in washington dc... not a spam site or untrustworthy. My guess is people are flaming this site because they don't like their politics
