  • Q: When should we use RGDP?

    A: RGDP is the real gross domestic product of a country in a given period of time. This is obtained by taking the nominal GDP of different countries and converting them into US dollars using purchasing power parities. RGDP is useful only for comparisons across countries at a given period of time. The term real signifies that price level differences across countries have been removed. See section 2.6 of UQICD User Guide.

  • Q: What is the practical difference between RGDP and CRGDP?

    A: RGDP represents real GDP of a country at a given year. It can be used in making spatial comparisons across countries at a given point of time. In contrast, CRGDP stands for real GDP at constant prices. CRGDP are expressed in the prices of a base year. For example CRGDP at 2005 prices means that the real GDP of countries in all years are expressed in terms of prices in 2005. It is necessary to use CRGDP when making comparisons over time and across countries. For example, CRGDP is useful if one wishes to compare the real per capita GDP of India in 2011 with that of China in 2005. See section 2.6 (and Appendix C) of the UQICD User Guide.

  • Q: Are RGDP and CRGDP available for Consumption, Government and Investment?

    A: Yes. UQICD provides PPPs, RGDP and CRGDP for GDP components.
