I need help on answering these questions on theories for my human service class

The demographic transition theory describes a set of interrelated social and demographic changes that contribute to astronomical growth and aging of the population (Morgan & Kunkel, 2011). The theory attributes a significant role to the timing, nature, and strength of declining birthrate and increased mortality. Analyze the demographic transition theory and its patterns and predictions. What implications does this theory have for family relationships in later life? What implications does it have for public policy concerning aging families? Support your position with scholarly and professional readings from current literature.
