Children described as 'Surplus' were living in Grange Hall because their existence was described as a crime against nature. The world was overpopulated, therefore, children born to couples were illegal.
Explanation:
In the novel, 'The Declaration,' by Gemma Malley, Scientists developed a drug named Longevity that was to stall death but not inhibit aging. This resulted in the overpopulation of the word. The government introduced a document, called 'The Declaration', in 2065 that stated that any who wishes to take the drug Longevity must not have children.
Those who flouted the law had their children killed in some nations but in other nations like Britain, they were described as 'surpluses' and kept in Grange Halls where they were subjected to hard labor. Their existence was viewed as illegal.
