Today marks the third International Migrants Day. It is an opportunity for all of us to pay tribute to the millions of migrants who leave their native countries in pursuit of improved standards of living for themselves and their families.

Today, there are more people living outside their countries of birth than ever before. In 2000, an estimated 175 million lived outside their country of birth. Of these, about 159 million were deemed international migrants; approximately 16 million were recognized refugees fleeing a well-founded fear of persecution; and 900,000 asylum seekers.

Behind these numbers are human stories: the skilled Nigerian computer engineer working in Sweden; the agricultural worker from Guatemala working illegally in the United States; the woman trafficked from Ukraine to Bosnia; the refugee from Afghanistan now in Pakistan and about to return home; and many, many more.

Immigrants and refugees should not – and must not - be seen as a burden. Those who risk their lives and those of their families are often those with the greatest ambition to make a better life for themselves, and they are willing to work for it. They do not leave their familiar surroundings, their culture or their families for a life of dependence, crime or discrimination thousands of kilometres away. They merely want a safer, more prosperous future for their children. If they are given a chance to make the most of their abilities, on an equal basis, the vast majority of them will be assets to society.
