Introduction

Global development is often discussed through simple binaries: rich versus poor, developed versus emerging, fast-growing versus left behind. But those labels hide a more complicated story. Some gaps remain stubbornly wide, especially in income, while others have narrowed dramatically, especially in health and connectivity.

This project compares developed and emerging markets from 1990 to 2022 using World Bank indicators. Across the visualizations below, I show that emerging markets have made real progress in life expectancy, internet access, and integration into the global economy, even though major economic divides still remain.

1. Where is the divide?

The world economy doesn’t divide neatly, but income-based classifications still reveal clear patterns. This map shows which countries the World Bank classifies as developed versus emerging based on national income levels in 2019. The geographic concentration is obvious: developed markets cluster in North America, Western Europe, and parts of East Asia, while emerging markets span much of Africa, Asia, and Latin America. Seeing the global structure helps frame the more detailed comparisons that follow.

2. Some gaps widen while others narrow

Income tells part of the story, but not all of it. These two charts track average GDP per capita and life expectancy from 1990 to 2022 for developed and emerging markets. The top panel shows that the income gap between the two groups has stayed large and may have even widened slightly over time. But the bottom panel tells a different story: life expectancy in emerging markets has improved dramatically, closing much of the gap with developed economies. The contrast between these trends is the central puzzle this project explores.

3. What does the world look like today?

Averages are useful, but they hide variation within each group. This bubble chart plots every country’s GDP per capita against life expectancy in 2019, with bubble size representing population. You can see that some emerging markets have life expectancy levels close to developed countries despite much lower incomes, while others lag behind on both dimensions. Hover over any bubble to see the exact numbers. The clustering shows that development is multidimensional, not just about income.

4. Who drives growth?

Fast growth is often associated with emerging markets, but the specific countries leading that growth change constantly. This animation shows the top 15 fastest-growing economies each year from 1990 to 2022. Watch how the rankings shift year to year, driven by booms, busts, and structural changes. Emerging markets dominate the leaderboard in most years, but developed economies occasionally break into the top ranks during recovery periods. The volatility itself is part of the story.

5. Which gaps closed and which stayed open?

Line charts show trends, but snapshot comparisons make the distance easier to see. This chart compares developed and emerging market averages in 1995 and 2019 for three key indicators. The thick gray line connecting the two points for each group shows how far they moved. On GDP per capita, both groups grew, but the gap barely narrowed. On life expectancy, emerging markets closed roughly half the gap. On internet access, the gap nearly disappeared. The pattern is clear: some dimensions converge much faster than others.

6. Regional leaders vary by dimension

Development isn’t one-dimensional, and no single region leads across all indicators. This heatmap ranks the seven major world regions on five different measures in 2019, with 1 being the best and 7 the worst. North America leads on GDP per capita and internet use, but lags on trade openness. East Asia ranks first on trade but lower on FDI. Europe and Central Asia performs well on life expectancy but middle-of-the-pack on income. The rankings show that there’s no single model of development.

7. Interactive exploration

The final two tools let you explore the data yourself. The Country Explorer app lets you pick any country and indicator to see how its trajectory compares with broader developed and emerging market trends. The EM/DM Dashboard lets you filter by year and region to see how distributions and averages change over time. Both apps are embedded below, and live links are included if you prefer to open them in a separate window.

This app lets the reader select a country and indicator to compare national trajectories with broader developed and emerging market patterns.
