After a holiday break, I am back.

Total global exports in 1980 were about $1 trillion. In 2018 they were $19.4 trillion. In the same period the number of persons living outside their country of birth went from 120 million to over 250 million (see graph).

Globalization links to international migration in several ways. Globalization of work makes more visible the disparities in income for the same work between countries.

An increase in the number of households with disposable income and more formal education increases the ease of migration.

Globalization, and migration, are aided by vast expansion of international air travel and by a huge drop in international communication barriers. International air travel in passengers grew from 640 million in 1980 to 4.2 billion in 2018.

Since 1990, remittance flows increased from $50B a year to over $550B.

It is not clear to me if and how globalization of work and trade leads to violent explosions of migration (Venezuela, Syria, Myanmar).
