Demographic Transition Activity

Modeling Demographic Transition Use chalk to draw and label you axis- Y axis = Birth and death rates per 1000 X- axis= Time (years) Use the chalk to divide the graph into the 4 stages Place the cards in the appropriate stages Use the RED string to represent Crude Birth Rates over time Use the Purple String to represent Crude Death rates over time Use the YELLOW string to represent growth rate over time

Phase I Phase 2 Phase 3 Phase 4 Pre-Industrial Transitional Industrial Post- Industrial To compensate for high infant mortality, the population experiences high birth rates. Population grows rapidly because birth rates remain high and death rates drop due to improved medical care, sanitation and food production. Large numbers of children become a financial burden rather than an asset. More time is spent pursuing education and availability of birth control allows people to have smaller families. Population growth begins to slow and then level off as low birth rates and low death rates cancel each other out.  The population grows very slowly or remains at a stable growth rate because of high death rates and high birth rates. Population momentum will cause a period of high growth because it takes at least one generation for people to adjust to reduced infant mortality. Population growth begins to slow as birth rates begin to decline and death rates remain low. High levels of affluence and economic development. High numbers of elderly people may create a tax burden. Often a subsistence economy where child labor is valued and increased family size is an economic advantage. Life expectancy is short and infant mortality rates are high.   Growth rate begins to decline. Growth rate is zero or low Growth rate is high Growth rate is low Growth Rate is Zero or negative Country: Lesotho CBR= 25, CDR= 23 India United States Italy
