According to the World Bank, India remains the world’s largest recipient of remittances, receiving around US$130 billion (≈ A$183 billion) annually in recent estimates — far ahead of any other country. These transfers support millions of households and strengthen India’s foreign-exchange reserves.
However, remittances represent only a portion of migrants’ total income. Migration research consistently shows that people working abroad send home just a fraction of what they earn. Studies and migration reports from the World Bank and the International Organization for Migration explain that remittance behaviour varies by income level and migration type but typically falls within a predictable range.
People of Indian origin rank among the highest-earning ethnic groups in several advanced economies, including Australia. High levels of education, strong representation in professional sectors and entrepreneurship have contributed to consistently above-average household incomes in these countries.
Across global migration research, economists commonly use a modelling range of 10–20% of migrant income being remitted. This range is widely used in migration economics to estimate total diaspora earnings when only remittance data is available.
Applying that standard modelling approach to India’s US$130 billion in remittances produces the following income range:
- If remittances equal 20% of income → diaspora earnings ≈ US$650 billion
- If remittances equal 15% of income → diaspora earnings ≈ US$870 billion
- If remittances equal 10% of income → diaspora earnings ≈ US$1.3 trillion
This places the most realistic midpoint near US$900 billion to US$1 trillion (≈ A$1.26T–A$1.40T) annually.

Additionally, a report titled India and its Diaspora: Partners in Progress by Indiaspora estimates that the Indian diaspora earns around US$730 billion (≈ A$1.05 trillion) annually.
