How Do We Measure Progress?

This is part 1 of a lengthy series of posts on measuring progress. Each post will consist of one means of measuring progress. In all these posts will present numeric data proving that progress exists today and it is widespread, even among the poorest nations.

In this blog I will write a series of posts showing evidence that we live in an era of great progress, and that progress benefits the vast majority of mankind. To prove that progress is taking and has taken place, we need objective means to measure it. Just pointing to a few examples where progress takes place is no more definitive than pointing to a few examples where progress does not take place. We must look for overall trends.

Unfortunately, there is no one metric that accounts for all dimensions of progress. So instead, I will take a broad approach by using many different development metrics. These metrics measure economic growth, poverty, agricultural production, diet, sanitation, drinking water, life expectancy, neonatal mortality, education, housing, happiness and more. I deliberately cast a broad net in order to capture as many dimensions of material well-being as possible.

One of the key problems with documenting progress is finding good metrics that both go far enough back in time and cover the entire world. Not surprisingly, there is far more data related to recently industrialized nations than those same societies in, say, 1500. Nor is it surprising that data is far easier to acquire for wealthy nations than poor nations. In many cases, I need to use different methods for different time periods and different nations. While not exactly comparing apples to oranges, it is a bit like comparing Gala apples and Red Delicious apples to Fuji apples. This is less than ideal, but it is hard to do otherwise.

The metrics that I use come from a wide range of official government and NGO sources. I present the metrics in a series of graphs. Unfortunately, the scope of the data is not easily digestible in static graphs. If you would like to inspect the data in more detail, I encourage you to explore two websites that have spent a great deal of time gathering important metrics: HumanProgress (at humanprogress.org) and Our World in Data (ourworldindata.org).

Since there are over 200 nations today, it is not realistic to examine development metrics for every one of them in this blog. And averages can cover up variation between rich and poor nations. We need a way to narrow the sample to a manageable number, but not do so in a way that creates a distorted impression of overall trends. In order to ensure that the data covers a very broad segment of the world’s population, I decided to focus on four distinct categories of nations. To reduce visual clutter I will show each group in a separate graph.

The first group, which I will call the “Wealthy 12”, consists of twelve Western nations that industrialized early and currently have very high standards-of-living. Those nations are the United States, United Kingdom, Australia, Belgium, Canada, France, Germany, Netherlands, New Zealand, Norway, Sweden, and Switzerland. The Wealthy 12 gives us a good overview of the trends within the wealthiest nations.

The second group that I will show data for is what I call the “Populace 12”. This group consists of twelve of the most populous nations that did not have high per capita GDP in 2018. This group consists of China, India, Brazil, Congo, Egypt, Ethiopia, Indonesia, Iran, Mexico, Nigeria, Pakistan, and Turkey. Together these nations make up 58% of the world’s population and cover every continent except Australia and Antarctica. The Populous 12 gives us a broad overview of trends for people who live outside the wealthiest nations.

The third group is what I call the “Bottom 20”. This group consists of the 20 nations with the lowest scores on the United Nations Human Development Index in 1990 (the earliest year available). The nations in this group consist of Afghanistan, Benin, Burma, Burundi, Central African Republic, Congo, Gambia, Guinea, Malawi, Mali, Mauritania, Mozambique, Niger, Papua New Guinea, Rwanda, Senegal, Sierra Leone, Sudan, Tanzania and Uganda. The Bottom 20 gives us a good overview in trends in the most desperately poor nations in the world. If there is any group of nations that should lack evidence of progress, it is these twenty nations.

The last group of nations is what I call the “Transformative 15”. This group consists of the nations that experienced at least one generation of very strong economic growth after 1950 (or 20+ years of per capita GDP growth of over 3 percent). This level of economic growth would lead to a doubling of the standard-of-living of their people within one generation.

The Transformative 15 includes representatives from many different regions and cultures: Spain, Ireland, Japan, Hong Kong, Taiwan, Thailand, Singapore, South Korea, Indonesia, China, India, Israel, Botswana, Trinidad, Puerto Rico and Chile. The Transformative 15 gives us a good overview of the nations who experienced the fastest economic growth. It tests whether very rapid economic growth translates into positive changes throughout the society.

Together, the Wealthy 12, Populous 12, Bottom 20 and Transformative 15 are a solid set of groups to test to whether the world has experienced widespread progress over the last few decades. Given the breadth and diversity of the four groups it seems unlikely that any broad trends will be missed by narrowing the sample from all nations in the world. In some cases, I will supplement these four groups with other data that seems relevant.

Each metric varies greatly in the number of nations and years with available data. I have done my best to be as comprehensive as possible given data that is accessible on the Internet. In order to facilitate visual inspection I have added an “Average” displayed in a thick black line wherever there are more than four nations with data. This average is sometimes jagged when individual data points are missing.

Wherever data permits, I will focus on women rather than the total population to show that progress has not excluded them. Note also that the use of these categories leads to some double counting. China, India and Indonesia are in both the Populace 12 and the Transformative 15. Congo is both in the Populace 12 and the Bottom 20.

In future posts, I will show you all the good data.
