It doesn't exist, or it shouldn't. It seems to be a synonym of paupericide ("death by destitution") surely badly inspired by aporophobia ("fear of poverty"), since there is a question of etymologies whereby crimes ending in -cidio have Latin origin and phobias are instead given a Greek origin. It is not a rule, but it is generally respected, and if variants have to be created because 'paupericide' can be interpreted as 'to murder a man because he is destitute' or also as 'to kill a group of people by submission to poverty', then Latin offers other variants, such as egenticide.
