Urban concentration is typically deemed to lead to greater national economic growth. This column challenges this view, using an original dataset covering 68 countries over the past three decades. Urban concentration levels have decreased or remained stable on average, though these averages hide widely diverging trends across countries. Although concentration has been beneficial for high-income countries, this hasn’t been the case for for developing countries.

Innovation is often concentrated in certain geographic areas, or ‘creative clusters’. This column uses novel data on famous births to explore the dynamics of creativity in European cities between the 11th and 19th centuries. The results show that creativity tends to precede economic prosperity, and that city institutions that protect personal and economic freedoms are conducive to radical innovation in a variety of domains.

Big cities have historically been seen as an important prerequisite for a country’s economic growth. In recent decades, however, developing countries have rapidly urbanised, and large cities are increasingly found in relatively poor countries. This column uses a new dataset to revisit the relationship between city size and economic growth. It finds that relatively small cities (with populations under three million) have been more conducive to economic growth, while very large cities are only growth-enhancing in countries with a very large urban population.

The distribution of talent and human capital is highly skewed across the world. As high-income countries engage in a global race for talent, the resulting migration of high-skilled workers across countries tilts the deck even further. This column draws upon newly available data to outline the patterns and implications of global talent mobility. Key results include recent dramatic increases in high-skilled migration flows, particularly in certain occupations, in certain countries, among those with higher skill levels, and from a wider range of origins.
