There is a certain formula that must be considered in order to understand how many children are legally available. On average, about 1,000 children from birth to 9 years of age for every population of 5 million will be orphaned each year. Unfortunately, only 20% of these children are legally available to be adopted, and half of these children will be adopted by locals of the respective country. So that drastically diminishes the number of available adoptees to only 100 out of a population of 5 million.
Use this formula to determine how many children are legally available to be adopted:
(.00002x)(.2)
2
where x = country population
