The Worlds Population Is Increasing
The World’s Population is increasing, but not evenly all over the world
Aim:
To find how the average line of latitude for the world’s largest cities has changed since 1950.
Hypothesis:
In the earlier years, the cities with the highest populations will be in HICs because these countries would have been the most developed, and these countries would have also been in the ‘rich north’.
Introduction:
As the world continues to develop, populations continue to increase as well. However, the populations of each country do not grow at the same rate. Some populations are rapidly increasing, whereas some country’s populations are barely increasing. The point of this investigation was to collect data for the top 10 most populated cities in 1950, 2000 and 2012. After this was done, the data could then be plotted onto a map, and trend lines could be drawn which then allowed us to discover patterns.
Method: 1. Collect data (preferably from the same source) of the top ten biggest cities in 1950, 2000 and 2012. 2. Plot all of this data onto a map. Make sure all of the data for each country is plotted in a different color. 3. Write the rank and the population under each city, and make sure you round the population to one decimal place. 4. Once all of the data has been plotted, using the same color for each year, plot a line of best fit between all of the points. Your line should be horizontal, and completely straight. 5. After you have plotted 3 lines, examine all patterns, and record them.
Analysis:
After analyzing the data, some patterns were discovered. In 1950, the top ten most populated cities were as an average, in the rich north. There were two cities in North America, and 4 cities in Europe. Most of these cities were in High Income Countries. The most populated city with 12.5 million people was New York City.
In 2000, most of the cities were in the ‘poor south’. There were only 2 cities (both in the USA) that weren’t in the
