Searching the world for one person was once inconceivable without the help of professionals. Today, Internet search technology significantly increases your chance of finding the person you seek. Tools that were once the sole domain of private investigators are now at our fingertips.
In 2009, more than a quarter of the world's population was online, according to the International Telecommunications Union. That means finding an old schoolmate, an absent family member, or a long lost friend might be just a click away.
Search social and professional networking sites. FaceBook and MySpace are the big dogs of social networking, with hundreds of millions of users; about half are from outside the United States, according to USA Today. Classmates.com, YouTube, LinkedIn and Twitter also have large international user bases useful for finding people internationally.
Other social and professional networking sites are popular in specific countries or regions. International networking sites include Badoo (Europe), Netlog (Europe, Quebec, Arab nations), Mactoob.com (Arab countries), XING (Europe, China), QQ.com and Renren (China), Multiply (Asia), Odnoklassniki and Vkontakte (Russia), Bigadda (India), Mixi (Japan), Orkut (Brazil and India) and Sonico (Latin America).
