Describe the 4 phases of demographic transition.

For each phase, compare crude birth rates (CBR) to crude death rates (CDR), and state whether the population is stable, growing, or declining in each. ·

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.

Note: When comparing and contrasting, include details for each of the entities being compared and contrasted. For example, if comparing availability of clean water in a developed country, contrast availability of clean water in a developing country.

Research and describe a program for developing countries that would help improve 1 of the 3 conditions that you compared.
