At the most basic level, a standard world map tells us almost nothing about human population. While the borders on a map may give us an idea of political boundaries or even aspects of continental geography, in reality they have little to do with showing population density. That said, it is possible to apply one simple alteration to the world map so that we can make it more interesting from a population perspective – and it turns out that doing so can help us gain insight on where regional population density is the greatest.
Splitting Up the Map
Today’s map comes from Reddit user /u/OrneryThroat and it breaks up the world by grouping countries into four equally populated regions. While both simple and crude, this mechanism does have some profound results: More specifically, there is one area that stands out from a visual standpoint, and it resides clearly in the southern portion of Asia.
Home to 1.34 billion people, it’s well-known that India already holds roughly 20% of the global population – but add Pakistan (195 million) and Bangladesh (165 million) into the mix, and you’re already closing in on one quarter of the global total. Meanwhile, to get to a similar number, you’d need to add the entire populations of North America, South America, Europe, and Oceania together to even come close.
Shown Another Way
While splitting it into four equal portions is one way to transform the world map, here is another geometric route to conveying a similar idea about the world’s population density:
On a previous Chart of the Week, we showed that 22 of the world’s 37 megacities are located in the small circle above, putting into perspective the region’s population density in a similar but different way. These simple transformations of the world map are not only memorable, but they also give our brain an easy heuristic to better understand the planet we live on. on Even while political regimes across these countries have changed over time, they’ve largely followed a few different types of governance. Today, every country can ultimately be classified into just nine broad forms of government systems. This map by Truman Du uses information from Wikipedia to map the government systems that rule the world today.
Countries By Type of Government
It’s important to note that this map charts government systems according to each country’s legal framework. Many countries have constitutions stating their de jure or legally recognized system of government, but their de facto or realized form of governance may be quite different. Here is a list of the stated government system of UN member states and observers as of January 2023: Let’s take a closer look at some of these systems.
Monarchies
Brought back into the spotlight after the death of Queen Elizabeth II of England in September 2022, this form of government has a single ruler. They carry titles from king and queen to sultan or emperor, and their government systems can be further divided into three modern types: constitutional, semi-constitutional, and absolute. A constitutional monarchy sees the monarch act as head of state within the parameters of a constitution, giving them little to no real power. For example, King Charles III is the head of 15 Commonwealth nations including Canada and Australia. However, each has their own head of government. On the other hand, a semi-constitutional monarchy lets the monarch or ruling royal family retain substantial political powers, as is the case in Jordan and Morocco. However, their monarchs still rule the country according to a democratic constitution and in concert with other institutions. Finally, an absolute monarchy is most like the monarchies of old, where the ruler has full power over governance, with modern examples including Saudi Arabia and Vatican City.
Republics
Unlike monarchies, the people hold the power in a republic government system, directly electing representatives to form government. Again, there are multiple types of modern republic governments: presidential, semi-presidential, and parliamentary. The presidential republic could be considered a direct progression from monarchies. This system has a strong and independent chief executive with extensive powers when it comes to domestic affairs and foreign policy. An example of this is the United States, where the President is both the head of state and the head of government. In a semi-presidential republic, the president is the head of state and has some executive powers that are independent of the legislature. However, the prime minister (or chancellor or equivalent title) is the head of government, responsible to the legislature along with the cabinet. Russia is a classic example of this type of government. The last type of republic system is parliamentary. In this system, the president is a figurehead, while the head of government holds real power and is validated by and accountable to the parliament. This type of system can be seen in Germany, Italy, and India and is akin to constitutional monarchies. It’s also important to point out that some parliamentary republic systems operate slightly differently. For example in South Africa, the president is both the head of state and government, but is elected directly by the legislature. This leaves them (and their ministries) potentially subject to parliamentary confidence.
One-Party State
Many of the systems above involve multiple political parties vying to rule and govern their respective countries. In a one-party state, also called a single-party state or single-party system, only one political party has the right to form government. All other political parties are either outlawed or only allowed limited participation in elections. In this system, a country’s head of state and head of government can be executive or ceremonial but political power is constitutionally linked to a single political movement. China is the most well-known example of this government system, with the General Secretary of the Communist Party of China ruling as the de facto leader since 1989.
Provisional
The final form of government is a provisional government formed as an interim or transitional government. In this system, an emergency governmental body is created to manage political transitions after the collapse of a government, or when a new state is formed. Often these evolve into fully constitutionalized systems, but sometimes they hold power for longer than expected. Some examples of countries that are considered provisional include Libya, Burkina Faso, and Chad.
