An unprecedented migration of women, particularly millennial women, has taken place from home to work across the Muslim world in the last 15 years.

Millions have joined the workforce for the first time, in a movement where economics trumps culture, writes Saadia Zahidi.

The Muslim world is not a monolithic body, but comprised of a diverse set of economies, cultures and geographies. Most of the world’s Muslims live in 30 emerging markets, in which they are the majority of the population. Together, these economies comprise 12% of the world’s GDP and one-fifth of its population.

These include countries with high per capita incomes such as Saudi Arabia, the United Arab Emirates, Qatar and Kuwait; upper middle income countries such as Malaysia, Turkey, Iran, Jordan and Tunisia; and lower middle income economies such as Morocco, Pakistan, Indonesia, Egypt, Bangladesh and Tajikistan.

Muslims are also younger than the global average, with a median age of 23 rather than 28 - a result of the Muslim world’s own "baby boom". Young Muslims are now the most educated in their countries’ histories, holding new attitudes and using new technologies.

Here are 10 things you need to know about the extraordinary rise of working women in this new generation:

1. Women are now the majority of university students in the Muslim world. Traditionally the minority in education, women are coming out ahead of men today. In Indonesia, the largest Muslim-majority country, women’s university enrolment has increased from 2% in 1970 to nearly 33% today, while men’s enrolment has increased from 4% to 29% over the same time period.

In Saudi Arabia ten years ago, about 30% of university-age women attended university. Today, half of them go - a higher proportion than in Mexico, China, Brazil and India. This is the base of talent for the new white-collar workforce of the Muslim world.

2. STEM education for women is a particular success story, setting up women in the Muslim world for the Fourth Industrial Revolution. In most countries across the world, women make up a much smaller proportion of those skilled in coding and the sciences more broadly. But there are five countries where, among students enrolled in science, technology, engineering and mathematics (STEM), women outnumber men. Two of these, Brunei and Kuwait, are Muslim-majority economies.
