Question for Ghana Statistical Service

Hilda Smiles is my name, a final year student offering social work at Kwame Nkrumah University of Science and Technology. I am doing my project on the topic: "social support systems for neglected children, a study at ayigya". Will like to know if i can get the population at ayigya and also the percentage of children from 8-17 years to help me get a sample size for my study.. Thanks..
