The graphic below (a Voronoi diagram) represents the relative size of each country’s economy in terms of nominal GDP: the larger the area, the larger the size of the economy. The areas are further divided into three sectors: services, industrial, and agricultural:  the darker the shade, the greater a nation’s reliance on that sector.

Finally, the graphic also shades the countries by continental geography, in order to visualize the relative economic contributions from North America, Europe, South America, Asia, Oceania, and Africa.

Clearly, United States boasts the largest share of the world’s economy at 23.32%, followed by China at 13.9%.  Is the US economy – at nearly a quarter of the world’s economy – a good thing or bad thing?

Interestingly, the US economy is mainly composed of companies engaged in providing services (79.7% compared to the global average of 63.6%), while agriculture and industry make up smaller-than-average of portions of the economy (1.12% and 19.1% compared to averages of 5.9% and 30.5%).

The next largest economy, China, is roughly balanced between industry and services (though the service sector is growing at a faster rate), with a 9.1% contribution from agriculture. In this sense, China is a bit of an anomaly: other rich countries have service sectors that greatly outweigh both industry and agriculture.
