The GDP per capita in Aruba is $25,300 while in Curacao it is $15,000

This entry shows GDP on a purchasing power parity basis divided by population as of 1 July for the same year. A nation's GDP at purchasing power parity (PPP) exchange rates is the sum value of all goods and services produced in the country valued at prices prevailing in the United States. This is the measure most economists prefer when looking at per-capita welfare and when comparing living conditions or use of resources across countries. The measure is difficult to compute, as a US dollar value has to be assigned to all goods and services in the country regardless of whether these goods and services have a direct equivalent in the United States (for example, the value of an ox-cart or non-US military equipment); as a result, PPP estimates for some countries are based on a small and sometimes different set of goods and services. In addition, many countries do not formally participate in the World Bank's PPP project that calculates these measures, so the resulting GDP estimates for these countries may lack precision. For many developing countries, PPP-based GDP measures are multiples of the official exchange rate (OER) measure. The differences between the OER- and PPP-denominated GDP values for most of the wealthy industrialized countries are generally much smaller.

Curacao consumes 20.5926 gallons of oil per day per capita while Aruba consumes 2.1504

This entry is the total oil consumed in gallons per day (gal/day) divided by the population. The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.

233 in every 100,000 people are currently imprisoned in Aruba compared to 285 in Curacao

This entry contains the number of people in penal institutions, including pre-trial detainees. Comparability is hampered by differences in local practice, including whether psychiatrically ill offenders are under the authority of the prison administration. People held in a form of custody not under the authority of a prison administration are not included in this figure.
