The ultimate population pyramid center! [] Most of the population in the world is clustered in East Asia, South Asia, Souteast Asia, and Europe. There are several other minor clusters in the world. People do not settle in wet, dry, cold, or high lands. =The Malthus Theory= This was the idea that population would increase faster than the food supply, eventually causing a mass starvation. So far, this hasn't proven to be true. He wrote all of this in his //An Essay on the Principle of Population// published in 1798. Want more information? [] =Why are birth rates declining?= More economic development and empowerment of women across the globe is causing a decline in birth rates.

=Summary of Population and Migration= The population of the world is growing at an unprecdented rate. Although, the theories of Thomas Malthus haven't come true, there are still many issues that have arisen. Among these issues is the spread of disease and malnutrition in many of the third world nations. It is because of many of these unsanitary living conditions that many choose to migrate. Remember, that most migrants are males without families. They are the most mobile. There can be other reasons for migration including push factors (such as poverty, flooding, war, oppression) and pull factors (such as nice weather, jobs, freedom). The United States is considered to be the melting pot of many migrants searching for a new home. In the 1700s, most immigrant to the US were from western Europe. In the late 1800s, many immigrants were from southern and eastern Europe. Today, many immigrants are from Latin America and Asia. However, in Europe and America, more and more immigration laws are being put back in place to deal with the influx of 3rd world immigrants. =Important Vocabulary for both chapters= =An essay question for you= What are the current issues in population and migration that we are seeing now in the world?
