•According to demographers, what factors lead to a decline of the CDR in phase two and the CBR in phase three of the demographic transition? ·
•Briefly describe 3 living conditions in developed countries that have reached phase four, and contrast them with these same conditions in developing countries that remain in earlier phases.
Research and describe a program for developing countries that would help improve 1 of the 3 conditions that you compared.
