Purpose: The purpose of this post is to determine and compare different aspects of demographic data among a variety of countries, such as population and age-dependency ratio.
1. China and India have the largest populations in the world. Which of these two countries adds more people to its population annually? [Calculate the numbers added by applying the rate of natural increase to the population of each country. Hint: the rate is a percent]
|Country||Number of people added annually|
I calculated the numbers by multiplying the rate of natural increase with the population of each country. After doing so, India had the greater outcome because there are more people than China that are added to the country each year.
- What proportion of the world’s people live the following continents/regions and what are the projected proportions by 2025 and 2050?
|Continent||% living today||% by 2025||% by 2050|
(My graph would not show up in the blog but here is a link to download and view it)
Series 1: Living today Series 2: Living by 2025 Series 3: Living by 2050
What trends are reflected in the bar chart?
Overall, population of people is decreasing as time goes on.
I calculated these numbers by dividing each population of each country by the population of the world as a whole. I repeated this procedure for the projected years of 2025 and 2050 but with the estimated and approximate values for those years.
- What proportion of the world’s people live in less developed countries (LDCs) and in more developed countries (MDCs) today? What proportion is projected to live in MDCs in 2025 and in 2050?
|Countries||% of world’s population today||% of world’s population in 2025||% of world’s population in 2050|
Discuss with your partner a) the economic and b) the social implications of the changing proportions of the world’s people in LDCs and MDCs. Record your observations.
Economically, people in LDC’s are unstable, most not having substantial jobs and education in general is not well implicated. Therefore, women especially resort to having children and raising a large family, this has become the natural way of life in these countries. On the other hand, MDC’s are much more work oriented, where adults are more focused on being successful and sustaining a well-off lifestyle. In this case, men and women are more career driven and do not have the time to raise a family, hence their being a lower population of children in MDC’s.
I deciphered these numbers by dividing the world population by the population of both MDC’s and LDC’s.
- Examine the crude birth rate, crude death rate, and rate of natural increase of any three countries (one being your own country) listed on the World Population Data Sheet.
|Country||Crude birth rate||Crude death rate||Rate of natural increase|
Discuss with your group partner the mathematical relationship among these three rates. Record your observations.
The death rate between these chosen three are all pretty close together, most likely because all of these are MDC’s. In terms of birth rate, they vary a bit, the highest being the U.S with 14 and Japan being the lowest with 9. However for the death rate, Greece has the highest of 10 while the US has the lowest of 8. In terms of the rate of natural increase, the U.S has the highest of .6% while Japan has a decrease of -0.0%. With this data there doesn’t seem to be a pattern between these three countries.
This comparison can be referenced to the textbook, being that population dynamics vary greatly, whether it be due to social and economic factors or natural forces that cause a population to grow or to decline.
