Nauru's heavy reliance on phosphate mining, combined with a lack of taxes and large government expenses, caused issues after the depletion of much of its reserves. The country came close to bankruptcy in 2000, and the unemployment rate rose to 90% in 2004. Nauru was for a time the world's RICHEST country (GDP per capita), but has since fallen in ranking to 117th place (World Bank, 2022).
