One of the key traits that make human beings unique on planet Earth is that we’re aware of our own mortality. Scientific advances have given us insight into which behaviors may prolong life, and which activities carry the greatest risk of death. Naturally, there have been some unique attempts to create a unified structure around risk and benefit, and to quantify every aspect of the human lifespan. As today’s graphic from TitleMax demonstrates, even when we’re thinking about death, the human desire to codify the world around us is alive and well.

Mortality Units

Certain events – such as a parachute failing to open or being hit by a meteor – have an easily quantifiable effect on life, but how do we measure the riskiness of day-to-day habits and situations? This is where a unique unit of measurement, micromorts, comes into play. This concept, invented by renowned decision analyst Ronald A. Howard, helps compare any number of potentially lethal risks. One micromort equals a one in a million chance of sudden death. Here’s the riskiness of various activities measured in micromorts:

Life Units

The average person, by the time they reach adulthood, will live approximately one million half-hours. Those 30 minute units are known as microlives. The microlife concept was invented by professor David Spiegelhalter as a way to measure the consequences of various behaviors. For example, 20 minutes of physical activity earns us two microlives, while watching TV for two hours subtracts one microlife. This measurement extends beyond nutrition and eating habits. Simply living in a modern era earns us an additional 15 microlives per day compared to those who lived a century earlier.

Casting the die on how we’ll die

How will the estimated 353,000 humans that will be born today eventually meet their end? This was the thought experiment conducted by Reddit user, Presneeze.

While our focus is often drawn to people who meet their end in spectacular and tragic ways, the vast majority of humanity will succumb to conditions such as heart disease and cancer. Geography can play a big role in shifting these odds:

In the United States, which is grappling with an opioid addiction crisis, there is a 1-in-96 chance of dying from a drug overdose. Diarrheal diseases may not be on the radar of most people living in first world countries, but in developing regions, they remain a leading cause of preventable death – particularly for children. In Russia, the odds are 1-in-4 that a man will not live beyond 55 years. The main culprit? Vodka.

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.
