Evolution of the Fertility, Life Expectancy, and Population in Different Parts of World
The code contains data on the fertility, life expectancy, and population numbers for 200 countries, as well as for different parts of the world, for groups of more- and less-developed countries, and for the whole world itself, for each year in the time span from 1950 to 2010. This Demonstration not only lets you display the data for these indices for the desired countries or regions, but also track the dynamics of data changes over time.[more]
You can select countries or country groups. By clicking the play button, you can track the tendency of yearly changes in the indices. You can also see the path of the changes in each country or region on the graph. To do so, change the view type from “bubble chart” to “path plot” and specify the required time range with the "year" slider. Mouse over a graphic object to see a tooltip with additional information about the country or the region.[less]
This Demonstration was inspired by a lecture by the statistician Hans Rosling , where he talks about software development for displaying statistical data. This Demonstration is similar to the graphic in the lecture but with some additional properties, discussed below.
Data on the countries and regions is displayed on the bubble chart, with fertility (the number of children per woman) on the horizontal axis and life expectancy on the vertical axis. The size of the circle indicates the population of the country or region. All the above-mentioned data is available to the public and was taken from the United Nations website [2–4].
The dynamic interface lets you choose one country or region (Snapshot 1), a group of countries (Snapshot 2), a group of regions (Snapshot 3), or the whole world. In Snapshot 4, trajectories of the two neighboring European countries and the two neighboring African countries are displayed, and both the correlations and differences between the neighboring countries of different continents can be clearly seen.
