This document introduces a new dataset on small and medium enterprises (SMEs) to fill gaps in cross-country SME data. The summary analyzes the dataset and finds:
1) Global SME lending is estimated to be $10 trillion, with 70% in high-income countries.
2) SME loans average 13% of GDP in developed countries and 3% in developing countries.
3) Differences in SME definitions across countries do not significantly impact cross-country comparisons of SME lending volumes.
