Gross domestic product
Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a period of time, often annually 
GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing differences in living standards between nations.
External debt of the Philippines
The Debt-to-GDP ratio is the proportion of a country's federal debt in relation to its total output or GDP. According to the Bangko Sentral ng Pilipinas (BSP), the ratio of what the Philippines owes from foreign creditors (external debt) to what it has been producing (GDP) has gone through a significant growth from 61.6% in 1999 to 68.2% in 2001. The ratio fluctuated until 2004 when it started a steady decline up to 2008. It rose again to 38.4% in 2009, but eventually fell down to 36.9% in 2010. Up until 2015, the trend was declining, with a 27.3% ratio at the end of 2014. Figures have generally been fluctuating (in terms of public and private external debt). Governments basically aim for low debt-to-GDP ratios because such is an indicator that the economy is producing high enough output to pay off its borrowings.
