69% of US wage earners comprise just 30% of cumulative net compensation

The bar-line chart below examines the cumulative number of US wage earners in different net compensation brackets and their contribution to the cumulative net compensation in 2017. In addition, a data row is used to detail the average net compensation and percent of wage earners for every bracket.

At the highest differential, 69% of wage earners comprise just 30% of cumulative net compensation. Note that at about 95% of wage earners, there is a discontinuity due a significant change in bracket definition.

Mekko chart showing number of wearables models available by location on body and purpose

The Mekko chart below shows the number of wearable models available based on where you wear the device and the purpose it serves. Each column represents the purpose and the width is proportional to the number of models available. Each row represents the location of the body where the device is worn and the height is proportional to its share within the column. In addition, we use a data row to show the average price for the devices by purpose.

3 quick takeaways:

  • Most devices are worn on the wrist
  • Most devices are used for lifestyle or fitness purposes
  • Entertainment devices are primarily worn on the head

Bar-line chart showing players with the most goals scored in World Cup matches

The bar-line chart below shows the numbers of goals scored in World Cup matches by the top 22 players. The bar indicates the number of goals and line shows the number of goals per game. In addition, we use data rows to list the number of games each athlete played in.

Miroslav Klose has scored the most the goals with 16 across 24 games. France’s Just Fontaine and Hungary’s Sándor Kocsis took only 6 and 5 games, respectively, to score 13 and 11 goals, having highest goals/game average and more than double the next highest.

Scatter plot showing changes in male and female tobacco smoking rates from 2000 to 2015

The scatter chart below shows the change in male and female tobacco smoking rates in different countries between 2000 and 2015. In addition, countries are color-coded by their income levels.

Almost all countries have seen female smoking rates drop – the Russian Federation and the Czech Republic are the two exceptions. Male smoking rates have also dropped in most countries. However, several African and Middle Eastern countries saw a rise.  The shaded green area indicates the part of the chart where both female and male smoking rates dropped.

Bar chart showing top 10 countries by internet speed

The bar chart below shows the top countries by average internet speed in Q4 of 2015. South Korea holds a significant advantage, almost 8Mpbs faster than second place Sweden. Data rows are used to show the percent of requests that were above 10 and 15Mbps. Includes business and residential connection speeds but excludes mobile connections.

2018 Winter Olympic medals normalized by team size

The bar-mekko chart below shows the number of Olympic medals won normalized by the team size. The width of each column represents the size of the team representing the country and height represents the medals they won per team member. As such, the area of the represents the number of medals won. 3 segments are used to separate out gold, silver, and bronze medals.

Visualizations of Olympic results typically show the total number of medals won by each country. However, each country sends different number of athletes based on a number of factors including qualifications. Showing the number of medals won normalized to team size would highlight the strengths of different teams.

The Netherlands won a shocking 0.61 medals per athlete they sent. Almost twice as much as the next closest country, Norway, which one the most medals. The Netherlands dominates speed skating which represents all the medals they won.

When the longest prime numbers were discovered

The line chart below shows when the longest prime numbers were discovered. Because the lengths vary greatly, a log axis is used.

The longest known prime number was discovered on Dec 26th, 2017 with a length of 23,249,425 digits, nearly 1 million digits longer than the previous record. The accelerated discovery of prime numbers is largely due to computing power and distribute computing projects like GIMPS.

Link between health spending and life expectancy

The scatter chart below shows the relationship between life expectancy and health expenditure for a variety of countries. The x-axis shows life expectancy at birth and the y-axis shows healthcare spend per capita for each year of life expectancy (in 2010 international dollars). Countries are color coded based on their region.

In general, the more countries spend on healthcare the longer their citizens live.  However, the US is a significant outlier. The US spends much more than any other country but its life expectancy is below many. The source article (https://ourworldindata.org/the-link-between-life-expectancy-and-health-spending-us-focus) plots health expenditure per capita on the y-axis (instead of healthcare spend per capita for each year of life expectancy). However, we find that their visualization is not as effective in calling out the US as an outlier.
