Back to the grind on research and writing

I am working on the definition of an orphan. The traditional view of an orphan is the loss of both parents.A UN expanded view in the 1990s states only one parent. They made this definition out of the AIDS epidemic in Africa. A wider view of social orphan includes a wide array of situations such as abandonment, separation due to war, legal such as loss of parental rights, trafficking, migration, etc.
The US Immigration has a definition for adoption purposes:

The United States defines an orphan for the purpose of immigration such as adoption. “The Immigration and Nationality Act provides a definition of an orphan for the purposes of immigration to the United States. A child may be considered an orphan because of the death or disappearance of, abandonment or desertion by, or separation or loss from, both parents”
