Lab Report over Population Pyramids of Afghanistan and Ireland

World Population Lab : Power of the Pyramids
Introduction:
The population of the world is slowly increasing. As the population grows the demands of the population grow. People need land to live on, wood for furniture ,etc. For all this, people cut down a lot of trees. This is very harmful for the earth's environment for it reduces the amount of oxygen in comparison to that of carbon dioxide. Therefore, all this would lead to global warming. The estimated population of the world today is 6,873,811,738. As the world’s population grows, improving living standards without destroying the environment is a global challenge. Crude birth rate is the nativity or childbirths per 1,000 people per year. Total fertility rate, which is the average number of children born to each woman over the course of her life. The crude death rate, is the total number of deaths per year. The replacement fertility rate is the number of children each woman needs to have to maintain current population levels. Ireland, , also called the Republic of Ireland, has a population of approximately 4.4 million. It’s a developed country that is located in Europe. Afghanistan is an developing country located in South-Central Asia. The hypothesis is that in 2050, Afghanistan’s population will increase.

Procedures:

1. Log onto the internet and go to http://www.census.gov/ipc/www/idbl
2. Click on World Population information
3. Then find the estimate of the population of the world today.
4. After that click on data access.
5. Find the country that was assigned
6. Then click on the year 2000, and sketch the histogram.
7. Then click on the year 2025, and sketch the histogram
8. Then click on the year 2050, and sketch the histogram
9. Repeat steps 5-8 for the second country that was assigned
10. Now click on demographic indicators
11. Copy the appropriate information needed to fill in the chart for 2000
12. Repeat step 11 for the years 2025, and 2050

Histograms:

Analysis:
Afghanistan’s population pyramids could be described as an Expansive pyramid. Each population pyramid 2000, 2025 and 2050 shows a broad base. This indicates a high proportion of children, a rapid rate of population growth, and low proportion of elderly people. The steady upwards narrowing shows that more people die at each higher age level. As for the Ireland’s population pyramid 2000, 2025, and 2050 is narrow at the base, wider in the middle, and stays quite wide until the very top, as there is a sizable percentage of older people.

Conclusion:
Afghanistan’s pyramid’s indicates a population in which there is a high birth rate, a high death rate and a short life expectancy. This is the typical pattern for less economically developed countries, due to little access to and motive to use birth control, environmental factors such as lack of clean water and poor access to health care. Net migration rate is the difference of immigrants and emigrants of an area in a period of time, divided (usually) per 1,000 inhabitants (considered on midterm population). A positive value represents more people entering the country than leaving it, while a negative value means more people leaving than entering it
