Assessing advances in the SDG framework is a multifaceted and complex endeavor. The framework encompasses five key pillars, often referred to as "The Five Ps": People, Planet, Prosperity, Peace, and Partnerships. These pillars collectively represent 17 distinct goals, each having specific targets slated for achievement by 2030. Progress on these targets is gauged through 248 separate indicators, where the progress of each indicator is measured through one or more variables.

Because most variables are measured on different scales, and not all indicators have explicit quantitative targets, there is no straightforward way to aggregate the individual indicators into a single measure of global progress. Judging the progress of each SDG therefore requires making many subjective decisions, all while incorporating expert opinions. This also means that the SDGs are not directly comparable, making it notoriously difficult to create a universal ranking.

The consensus among experts is clear, however: the world is not on track to achieve the SDGs. Temperatures are rising, biodiversity is eroding, and inequality deprives millions of people from access to basic amenities. This conclusion is clear both from the Sustainable Development Report, which shows each country’s performance per SDG, and the SDG Tracker by Our World in Data, which shows the development of individual variables over time.

All the same, we can’t help but wonder: what’s the progress across the SDGs in terms of the average person?

For our analysis, we adopt a simple, holistic methodology to measure progress. We select from all available indicators those that (1) have sufficient data coverage for countries (cross-sectional) and years (longitudinal), (2) are readily available, and (3) are comparable between countries.

If data for a country is not available for recent years, we take the last known value. If a country starts reporting data later than other countries, we instead use the first reported value for that country. Although we recognize that making these assumptions for missing data is not ideal, we believe it outweighs the alternative of having global values jump up and down due to individual countries entering and leaving the sample.

For each indicator, we then use the country values to calculate the 10th and 90th population-weighted percentiles in 2015. Using these percentiles, we standardize the data of each country to a value between 0 (average result is worse than the 10th percentile of the global population in 2015) and 1 (an outcome superior to 90% of the population in 2015). We then aggregate the country data to a global value on a per capita basis. After repeating this procedure for every indicator, we take the simple average over all indicators for each target, and average again for all targets per goal. These values yield a composite progress measure for each SDG.

Although this approach is simplistic, using it consistently for each indicator makes them comparable and allows us to aggregate indicators into single SDG progress metrics – our ultimate goal for this visual. This methodology also enables us to examine pre-2015 data for a longer view of global progress.

Note that this approach overlooks expert opinions and specific SDG targets. Additionally, by analyzing all SDGs from a relative (to 2015), and per capita basis, our analysis might be overly optimistic. For example, Indicator 13.2.2 aims to integrate climate change measures into national policies, which can be interpreted as implying that the world should achieve zero emissions by 2030. In our analysis, however, we would consider indicator 13.2.2 to have been achieved when the average global per capita emissions are below that of the lowest emitting 10% of the population in 2015.

Our visual representation reveals mixed progress across the SDGs since 2000. While Goals 4 (Quality Education), 7 (Affordable and Clean Energy), and 13 (Climate Action) appear promising, the overall progress since the SDGs’ initiation is not uniformly encouraging. For instance, Climate Action has seen advances in disaster risk strategies but continues to struggle with rising greenhouse gas emissions. The data also suggests slow progress in SDGs related to Zero Hunger, Decent Work and Economic Growth, Sustainable Cities and Communities, Life Below Water and Life on Land.

If trends persist, the timeline for achieving most of the SDGs could extend far beyond 2030. So, despite some progress, a significant gap remains in achieving the goals within the stipulated time frame. Urgent action is needed, particularly by governments, to accelerate progress towards a sustainable and equitable future for all.
