More than 200 million migrants relocate each year globally, according to a study posted on Oxford Scholarship Online.

About 500,000 arrive in the United States annually. Many of them are from families who have adopted transnational lifestyles after settling in their new country - often after their children are born.

According to a paper published by Oxford Scholarship Online, it is believed that every year in large urban centers in the US and Canada a significant number of infants and toddlers experience separations from their parents.
