Data about income patterns, income distribution in the US for households over the last 50 years are collected and reported here. The data demonstrate how the income of households has changed over the years.
The statistics are equally representative of the relationship between a generation’s wealth, health and welfare.
The data were displayed in a graph showing the income distribution between the various countries in the US. The data is also representative of different races in the United States, the African Americans households, white households among other races are well represented in the study.
The site provides a database that analyses income inequality indices from 1962 to 2011, illustrating how income distribution has been changing over time. In some states, the Lorenz curve has moved towards the line of equality, which means that the income distribution has improved, while in other parts of the country, it has moved further away from the line of equality, hence showing that the income distribution has deteriorated.
The data has also been visualized correctly, providing an exceptionally interactive visualization tool.
Two Types of Research Questions That Might Be Explored Using the Data
a. What is the correlation between income dynamics of a household and the health of the household??
b. How do ethnic and racial orientation influence income dynamics in the United States??
The Best Stats You’ve Ever Seen
One of the most interesting facts about this video is how the data is being represented. Particularly, Rosling begins by describing the fertility rates in different countries in a graph in which the countries are represented by the circles, with the size of the circle depicting the population of the country. Such presentation helped to demolish the fallacy that the world is divided into “we” and “them.” With “we” representing the western developed countries characterized by small families and long lifespan, “them” is depicting large families and short life peculiar to less developed parts of the world. It was discovered that the trends have changed from the 1960s, and an example can be that so far, the size of the family has changed in developing countries. Secondly, another interesting fact about the video is how the author is representing the world income distribution, showing how that the few wealthiest people owned most of the riches of the world in the 1980s. However, this trend has slightly changed, especially in Asia, where more people have pulled out from poverty with time, with most of the people going to the middle class. The data has been presented in charts showing how the income distribution changed from year to year.
The Beauty of Data Visualization
The interesting point in this video is that the significance of visualization as the tool used to find the connection between data is explained. One might have such a wide data load that it can be impossible to make sense out of it, and in such instance, visualization would help to get the relation between different data sets (Yao, Hu, Yu, & Grzymala-Busse, 2015). Visualizing helps in getting the pattern within the data, hence deriving information (Spencer, 2017). From the video, visualization has been useful in coming up with the billion-dollar O-gram, which is a visualization tool that uses colored boxes to explain data set representation.
In summary, the videos are well presented and provide the opportunity to learn a lot from the presentation of data to get meaning and patterns out of the data sets.
