The lottery was created to maintain diversity in the U.S. Immigrant Population. It is designed to give people from countries with least number of U.S. immigrants a better chance. Countries with the lowest amount of immigrants, such as Kenya and Nigeria, are awarded the most winners, Countries with the highest number of immigrants are allocated the fewest winners. Those with very high numbers of U.S. immigrants such as Mexico, China and Canada, are disqualified - no winners.
