Consumer indebtedness differs significantly from a country to a country. While average Dutch owes to banks more than USD 55,000 (of which 94% comes from mortgage lending), Armenians or Georgians have borrowed only USD 400 per capita, on average at the end of 2012 (more details at www.helgilibrary.com/indicators/index/retail-loans-per-capita-usd).
Many things affect the consumer indebtedness - overall development of the economy, structure of the banking system, culture, or religion, to mention a few. The correlation is clear, however, the richer and more liberal, the more indebted society. While retail loans account for more than 100% of GDP in Netherlands, it is less than 15% in Georgia, for instance.
