South Korea's rigorous education system and the establishment of a highly motivated and educated populace is largely responsible for spurring the country's high technology boom and rapid economic development. Having almost no natural resources and a high population density in its territory, which deterred continued population growth and the formation of a large internal consumer market, South Korea adapted an export-oriented economic strategy to fuel its economy, and in 2019, South Korea was the eighth largest exporter and eighth largest importer in the world. Bank of Korea and Korea Development Institute periodically release major economic indicators and economic trends of the economy of South Korea.
