How Has Car Safety Improved Over 60 Years?

Did you know that in 2019, there were 6.7 million car accidents in the U.S. alone?

This resulted in 36,096 deaths over the year—an awful statistic to say the least—but one that would be much worse if it weren’t for seatbelts, airbags, and other modern safety devices.

In this infographic, we’ve visualized data from the U.S. Bureau of Transportation to show how breakthroughs in car safety have drastically reduced the number of motor vehicle fatalities.

Measuring Safety Improvements

The data shows the number of fatalities for every 100 million miles driven. From a high of 5.1 in 1960 (the first year data is available), we can see that this metric has fallen by 78% to just 1.1.

YearFatilities per 100 million miles
19605.1
19704.7
19803.4
19902.1
20001.5
20101.1
20191.1

What makes this even more impressive is the fact that there are more cars on the road today than in 1960. This can be measured by the total number of miles driven each year.

Vehicle Miles Driven

So, while the total number of miles driven has increased by 371%, the rate of fatalities has decreased by 78%. Below, we’ll take a closer look at some important car safety innovations.

1. The Seatbelt

The introduction of seatbelts was a major stepping stone for improving car safety, especially as vehicles became capable of higher speeds.

The first iteration of seatbelts were a 2-point design because they only looped across a person’s waist (and thus had 2 points of mounting). This design is flawed because it doesn’t hold our upper body in place during a collision.

Today’s seatbelts use a 3-point design which was developed in 1959 by Nils Bohlin, an engineer at Volvo. This design adds a shoulder belt that holds our torso in place during a collision. It took many years for Volvo to not only develop the device, but also to convince the public to use it. The U.S., for instance, did not mandate 3-point seatbelts until 1973.

2. The Airbag

The concept of an airbag is relatively simple—rather than smacking our face against the steering wheel, we cushion the blow with an inflatable pillow.

In practice, however, airbags need to be very precise because it takes just 50 milliseconds for our heads to collide with the wheel in a frontal crash. To inflate in such a short period of time, airbags rely on a chemical reaction using sodium azide.

The design of an airbag’s internal mechanism can also cause issues, as was discovered during the Takata airbag recall. As these airbags inflated, there was a chance for them to also send metal shards flying through the cabin at high speeds.

Dual front airbags (one for each side) were mandated by the U.S. government in 1998. Today, many cars offer side curtain airbags as an option, but these are not required by law.

3. The Backup Camera

Backup cameras became a legal requirement in May 2018, making them one of the newest pieces of standard safety equipment in the U.S. These cameras are designed to reduce the number of backover crashes involving objects, pedestrians, or other cars.

Measuring the safety benefits of backup cameras can be tricky, but a 2014 study did conclude that cameras were useful for preventing collisions. A common criticism of backup cameras is that they limit our field of vision, as opposed to simply turning our heads to face the rear.

Taking Car Safety to the Next Level

According to the National Highway Traffic Safety Administration (NHTSA), having both seatbelts and airbags can reduce the chance of death from a head-on collision by 61%. That’s a big reduction, but there’s still plenty of room left on the table for further improvements.

As a result, automakers have been equipping their cars with many technology-enabled safety measures. This includes pre-collision assist systems which use sensors and cameras to help prevent an accident. These systems can prevent you from drifting into another lane (by actually adjusting the steering wheel), or apply the brakes to mitigate an imminent frontal collision.

Whether these systems have any meaningful benefit remains to be seen. Referring to the table above shows that fatalities per 100 million miles have not fallen any further since 2010.

Charted: The Number of Democracies Globally

How many democracies does the world have? This visual shows the change since 1945 and the top nations becoming more (and less) democratic.

Charted: The Number of Democracies Globally

The end of World War II in 1945 was a turning point for democracies around the world.

Before this critical turning point in geopolitics, democracies made up only a small number of the world’s countries, both legally and in practice. However, over the course of the next six decades, the number of democratic nations would more than quadruple.

Interestingly, studies have found that this trend has recently reversed as of the 2010s, with democracies and non-democracies now in a deadlock.

In this visualization, Staffan Landin uses data from V-DEM’s Electoral Democratic Index (EDI) to highlight the changing face of global politics over the past two decades and the nations that contributed the most to this change.

The Methodology

V-DEM’s EDI attempts to measure democratic development in a comprehensive way, through the contributions of 3,700 experts from countries around the world.

Instead of relying on each nation’s legally recognized system of government, the EDI analyzes the level of electoral democracy in countries on a range of indicators, including:

  • Free and fair elections
  • Rule of law
  • Alternative sources of information and association
  • Freedom of expression

Countries are assigned a score on a scale from 0 to 1, with higher scores indicating a higher level of democracy. Each is also categorized into four types of functional government, from liberal and electoral democracies to electoral and closed autocracies.

Which Countries Have Declined the Most?

The EDI found that numerous countries around the world saw declines in democracy over the past two decades. Here are the 10 countries that saw the steepest decline in EDI score since 2010:

CountryDemocracy Index (2010)Democracy Index (2022)Points Lost
🇭🇺 Hungary0.800.46-34
🇵🇱 Poland0.890.59-30
🇷🇸 Serbia0.610.34-27
🇹🇷 Türkiye0.550.28-27
🇮🇳 India0.710.44-27
🇲🇱 Mali0.510.25-26
🇹🇭 Thailand0.440.20-24
🇦🇫 Afghanistan0.380.16-22
🇧🇷 Brazil0.880.66-22
🇧🇯 Benin0.640.42-22

Central and Eastern Europe was home to three of the countries seeing the largest declines in democracy. Hungary, Poland, and Serbia lead the table, with Hungary and Serbia in particular dropping below scores of 0.5.

Some of the world’s largest countries by population also decreased significantly, including India and Brazil. Across most of the top 10, the “freedom of expression” indicator was hit particularly hard, with notable increases in media censorship to be found in Afghanistan and Brazil.

Countries Becoming More Democratic

Here are the 10 countries that saw the largest increase in EDI score since 2010:

CountryDemocracy Index (2010)Democracy Index (2022)Points Gained
🇦🇲 Armenia0.340.74+40
🇫🇯 Fiji0.140.40+26
🇬🇲 The Gambia0.250.50+25
🇸🇨 Seychelles0.450.67+22
🇲🇬 Madagascar0.280.48+20
🇹🇳 Tunisia0.400.56+16
🇱🇰 Sri Lanka0.420.57+15
🇬🇼 Guinea-Bissau0.410.56+15
🇲🇩 Moldova0.590.74+15
🇳🇵 Nepal0.460.59+13

Armenia, Fiji, and Seychelles saw significant improvement in the autonomy of their electoral management bodies in the last 10 years. Partially as a result, both Armenia and Seychelles have seen their scores rise above 0.5.

The Gambia also saw great improvement across many election indicators, including the quality of voter registries, vote buying, and election violence. It was one of five African countries to make the top 10 most improved democracies.

With the total number of democracies and non-democracies almost tied over the past four years, it is hard to predict the political atmosphere in the future.
