BR: 2/17/17 How do landforms affect where people live, in your opinion? Explain:

World Geography Ch. 3.1 World Population The World’s population is growing incredibly fast, leading to new challenges. It is also distributed unevenly, and movement occurs frequently.

Population Growth The world’s population overall has increased dramatically in the past 200 years, going from 1 Billion around 1800, to 7.5 Billion today. For example, check out the following diagram: How about where you live? Is the area growing, or shrinking? Write it down, then share with a neighbor! Springville for example has grown a lot, especially in the local area. Spanish Fork has tripled in the last 20 years! LINK

So Why Does Population Grow? One reason is that the death rate has declined. The death rate is the number of deaths every years per 1000 people living. More people are staying alive longer, increasing the population. This is due to better healthcare and increased food supplies. One more reason is continued high birthrates. The Birthrate is the #s of births every year / 1000 people. Many developed countries have a low birthrate, while underdeveloped or developing countries (esp. India, SE Asia, Africa, Latin America, etc.) have very high birthrates. Babies also live longer, thanks to better healthcare.

Challenges of Population Growth More food of course is a necessity for more people, as is more potable water. Advances in technology have helped with this, such as better irrigation methods, breeding / creation of more productive / hardier plants, etc., has helped. VID Yet challenges do remain. For example, war, crop failures, climate change, etc. can lead to severe food shortages. Water is limited, and keeping it clean for everyone is a challenge, as is provided public services, like hospitals and schools for all these additional people.

Where People Live Human populations across the globe are scattered and gathered unevenly. What areas do you think would most attract people (aka “pull” factors) Generally, people gather in areas that: Have fertile soil Mild climates Natural / water resources readily available TPS: What would be your ideal place? Cities often provide jobs and other opportunities that rural areas do not, which explains why people gather there. Link

Population Density To figure out how densely populated an area is, they measure how many people live in a given area, like a square kilometer or mile. Total Population / total land area = Population Density. So what does that look like? Well, Malaysia and Norway for example have about the same land area, around 130,000 sq. miles. Norway has about 37 people / sq. mile, while Malaysia has about 205 people / sq. mile. NORVID; MalVID Keep in mind however, that these numbers are averages. Not every part of Malaysia has that many people living in every square mile. Argentina, for example, has an average of 36 people / sq. mile, but the city of Buenos Aires has some areas that are as high as +5,500 people in one square mile! LINK

Population Movement Throughout history, there have been large movements, or migrations, of people going from one place to another! If people are staying within a country, this is known as internal migration. Another type of migration that we have seen in recent years is people leaving farms and villages for cities and urban areas, often in search of work. This is known as urbanization. This has been occurring especially quickly in Asia, Latin America, and Africa. VID When people move between countries, this is called international migration. When refugees for example emigrate (exit; immigrant = come into) from their country, they are now emigrants from their old country, and immigrants to their new one.

Why Migrate? There are many reasons. We generally call these push and pull factors. For example, few jobs in an area where one lives would be a push factor, encouraging them to leave and look for work elsewhere. Conversely, a place that has lots of job openings would be considered a pull factor to those looking for work. There are many people who are “pushed” out of a country by war, persecution, disasters, etc., and these people are known as refugees. The impact these people have is also important. Countries may become overcrowded with new immigrants, while countries with too many emigrants may lose valuable skilled workers. Mixing of culture also occurs, which is sometimes embraced, but also resented by native-born citizens as well, leading to violence and other issues.

HW: Choose one of the following: Option A: Do some research on one of the three main ideas discussed today options (Population Growth, Where People Live, Population Movement, etc.), and then create a story that tells us more about your chosen topic (for instance, for Pop. Movement, the reasons for a person’s migration, difficulties faced, etc. Option B & C: Do some research, then create a slideshow presentation or a Poster on one of the topic options (Population Growth, Where People Live, Population Movement, etc.), showing us what you learned and the importance of understanding it better. For all of these options, see the class handouts:
