Population Pyramids What is a population pyramid? A bar graph that shows % of population in different age groups in a country. The shape of a country’s population pyramid can tell as a lot about a country, including it’s place in the Demographic Transition

Basic Pyramid Shapes/ Stages of DTM

An Interesting One…China

Thomas Malthus Who was Thomas Malthus? English Economist (1766-1834) Argued that population was growing too fast…food supply would not keep up! Starvation, war, chaos!

Was Malthus right? Neo (new)- Malthusians Yea boi! Hecky no! Neo (new)- Malthusians Rapid pop. growth in LDC’s (due to medicine and tech)puts a strain on these countries. Population is outstripping a variety of resources, not just food ie- oil, fresh water, arable land Humans are able to adapt (possibilism) and create new sources of food GMO’s, commercial farming Larger population = more workers/ ideas (Ester Boserup) We have the resources, but they aren’t equally shared (Marx/Engels)

Lowering the NIR How do we get NIR down? Two options 1. Lower Birth Rates 2. Raise Death Rates Let’s go with option #1, because nobody likes dying.

How do we lower birth rates? Empower Women Contraceptives More $$$ spent on education Women attend school/ college Become employed, work more, make fewer babies Better education about reproductive health Economic development/ education is a long term solution….what about the short term? Distribute contraceptives widely and cheaply. Less than 25% in SS Africa Over 65% in Asia/LA Some oppose birth control methods, primarily due to religious reasons.
