Every year millions of people migrate around the globe.  ImmiViz helps foster the conversation on migration by visualizing data about the costs and opportunities of migration.




Remittances sent home by migrants to developing countries are equivalent to more than three times the size of official development assistance.

Cutting prices by at least 5 percentage points can save up to $16 billion a year.

ImmiViz is an interactive tool designed to help advocates, journalists and communities better understand the costs and results of migration.  Remittances (money sent home by migrants) have a huge impact on the economies of recipient countries.  The personal impact of remittances, and some of the challenges faced by migrants on their journeys to be in a position where they can send money home, are illustrated in the Stories section of the website.

Remittances could go even further toward ending extreme poverty if the sending and receiving costs were lowered.  Extreme poverty is defined by the World Bank as living on $1.25 or less per day (  Cutting the costs associated with remittances could have a great impact in this area, as the Numbers section of the website shows.

Many factors go into determining the transaction fees associated with remittances, but hopefully by visualizing some of the costs and impacts of remittances this site can help move the discussion on this topic forward.

The number of people living on less than $1.25 per day was drawn from the World Bank’s ‘World Development Indicators: Poverty rates at international poverty lines’ (
