Using US data, Todd Schoellman Schoellman and Vladimir Smirnyagin show that the link between university R&D expenditures and local patenting activities has strengthened since the 1980s and that the effect is driven by local knowledge spillovers. www.sciencedirect.com/science/arti... #academia

How can we measure the state of democracy around the world? Measuring democracy is challenging. It has many dimensions, and researchers assess them in different ways. No single source of data captures the full picture, so we present data from several of them.
Choropleth map of country-level Liberal Democracy Index for 2025 where it highlights global differences in democratic scores on a scale from 0 to 1. High scores are concentrated in North America, Western and Northern Europe, Australia and New Zealand, while lower scores appear across parts of Africa, the Middle East, and Central and East Asia; many countries in Latin America and southern Africa show intermediate values. A few areas are marked as having no data. The data source is the Varieties of Democracy (V-Dem) project (2026). The chart is licensed CC BY to Our World in Data.

What happens when the state quietly disappears? A new paper finds that support for populism in Italy (2008–18) rose where hospitals closed, especially in remote municipalities. Greater distance to public services reinforced feelings of abandonment and boosted populist voting.

📊 Data update: How many people live in poverty around the world, and how has that changed over the last decades? The World Bank's Poverty and Inequality Platform (PIP) is one of the primary tools we have for answering these questions.
Stacked area chart of total population living in extreme poverty (below $3 per day) by world region from 1990 to 2026, where global numbers fall from about 2.3 billion in 1990 to under 1 billion in 2026, driven mainly by large declines in East Asia & Pacific and South Asia. Sub-Saharan Africa's count remains high and becomes a larger share of global poverty over time. Data source: Lakner et al. (2025), updated using World Bank PIP in March 2026. License: CC BY.

Was the global decline of extreme poverty only due to China? The share of the world population living in extreme poverty has never declined as rapidly as in the past three decades.
Extreme poverty fell sharply worldwide – even excluding China.

Line chart of global extreme poverty rate, 1990 to 2025. Extreme poverty is defined as living below the international poverty line of $3 per day; data are adjusted for inflation and differences in living costs between countries. The chart shows global extreme poverty reduced from 43% to 10%, and the series excluding China reduced from 33% to 12%, with the two lines converging by around the mid-2000s and continuing to decline toward 2025. Y axis runs from 0% to 50%; x axis runs from 1990 to 2025. Data source: World Bank Poverty and Inequality Platform (2025); OurWorldInData.org/poverty. License: CC BY.

The world as 100 people over the last two centuries
An image with 6 charts showing the world as 100 people over the last two centuries. The charts cover poverty, basic education, literacy, democracy, vaccination, and child mortality. As one example, 79 out of 100 people globally were living in extreme poverty in 1820. By 2018, that had decreased to 9 people.

Data sources: Poverty: Michailis Moatsos (2021).
