Among 10 countries with the estimated net outflow of migrants exceeding 1 million over the period from 2010 through 2021, Pakistan saw 16.5 million migrants move overseas, the highest in the world, according to a report titled "World Population Prospects 2022" released by the United Nations Department of Economic and Social Affairs (UN DESA).

In many of these countries with more than one million people leaving, the outflows were due to temporary labor movements, such as for Pakistan (net outflow of 16.5 million), India (3.5 million), Bangladesh, (2.9 million), Nepal (1.6 million) and Sri Lanka (1.0 million).  The report also said that India's population will surpass China's in 2023. Over half of the global population increase up to 2050 will be in just 8 countries: Democratic Republic of Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines & Tanzania.

The figure of 16.5 million migrants outflow from Pakistan is much higher than the numbers reported by the Bureau of Emigration & Overseas Employment of the Government of Pakistan. A possible source of discrepancy is the uncounted numbers of the family members who accompany workers going abroad for work.

Top Remittance Receiving Countries in 2021. Source: World Bank

Pakistan has received nearly $31 billion in worker remittances in 2021, up a whopping 20% from the prior year, according to the World Bank. This is a new record representing nearly 10% of the country's gross domestic product (GDP). This money helps the nation cope with its perennial current account deficits. It also provides a lifeline for millions of Pakistani families who use the money to pay for food, education, healthcare and housing. This results in an increase in stimulus spending that has a multiplier effect in terms of employment in service industries ranging from retail sales to restaurants and entertainment. 

Remittances from the European Union (EU) to Pakistan soared 49.7% in FY 21 and 28.3% in FY22, according to the State Bank of Pakistan. With $2.5 billion remittances in the first 9 months (July-March) of the current fiscal year, the EU ($2.5 billion) has now surpassed North America ($2.2 billion) to become the third largest source of inflows to Pakistan after the Middle East and the United Kingdom. Remittances from the US have grown 21%, second fastest after the EU (28.3%) in the first 9  months of the current fiscal year. 

Pakistan's share of the working age population (15-64 years) is growing as the country's birth rate declines, a phenomenon called demographic dividend. This dividend is manifesting itself in high levels of worker exports and record remittances pouring into the country. Saudi Arabia and the United Arab Emirates(UAE) are the top two sources of remittances but the biggest increase (58%) in remittances is seen this year from Pakistanis in the next two sources: the United Kingdom and the United States.

A common myth about emigration is that it is driven by poverty. But the fact is that the poorest and least developed people tend to stay put where they are; they do not migrate. It's only people who have a certain level of income and skills who are more likely to migrate to other countries for better opportunities. This fact has been well-established by multiple studies conducted in Africa.

Here's an except of African Development Bank report on migration:

"Results show that despite increase in the absolute number of migrants, Africa, particularly SubSaharan Africa has one of the lowest rate of emigration in the world .... Poorer countries generally have lower rate of emigration ......Bad socio-economic conditions generally seem to lead to higher rate of emigration by highly skilled individuals. Generally, migration is driven by motives to improve livelihoods with notable evidence on changes in labor market status. Often, self-employed or unemployed émigré ended up in wage employment. The paper outlines policy issues emerging from the migration trend in Africa."

Migration vs Human Development Source: Hein de Haas

Data shows that increased human and economic development is initially associated with increasing emigration. Any form of development in the poorest countries of the world is therefore likely to lead to accelerating emigration. Such findings contradict conventional thinking and force us to radically change our views on migration. Such rethinking can be achieved by learning to see migration as an intrinsic part of broader development processes rather than as a problem to be solved, or the temporary response to development “disequilibria”, according to The Conversation, a US publication.
