Description

These data provide estimates of GDP per capita of independent states. The core input data used is PWT 8.0. Unlike previous versions of the GDP data this reports PPP estimates of real GDP rather than per capita GDP.

These data are explained in greater detail in Gleditsch, Kristian S. 2002. "Expanded Trade and GDP Data," Journal of Conflict Resolution 46: 712-24. http://jcr.sagepub.com/content/46/5/712.short.

Table of Origin Codes

Population figures: Origins and exceptions

a) All missing population figures in the PWT data have been replaced by population figures from the Expanded Population Data v.2.0, compiled by Kristian Skrede Gleditsch. This file is is provided as ksgmdw/countrypopestimates.asc, see the associated readme file for details on the origin codes. No documention is available as of yet for these data. These estimates are generally based on country specific censuses, and the particular references for each are available on request.

b) The PWT populations estimates have been retained when available, with some exceptions

The PWT project lists population figures for countries that experience large boundary changes based on the current size of the existing state. This means that the PWT population figures for the Federal Republic of Germany *before* the end of the German Democratic Republic reflect the population size of the two Germanies combined. Likewise, pre-1991 population figures for the Soviet Union reflect the size of present day Russia, even though this is only about half the size of former Soviet Union. I am grateful to Ye Wang from the PWT project for explicity confirming this to me.

Since the present size of a state seems inappropriate for historical comparisons, the current version of the data replaces the PWT figures with estimates from the Expanded Population Data v.2.0 in the following instances:

A. Population of states prior to merging with other states i) Federal Republic of Germany through 1990 (prior to inclusion of former Democratic Republic of Germany) ii) Democratic Republic of Vietnam through 1975 (prior to inclusion of former Republic of (South) Vietnam iii) Arab Republic of (North) Yemen through 1990 (prior to merger with former People's Republic of (South) Yemen

B. Population of states prior to secession of new states i) Pakistan through 1970 (prior to secession of Bangladesh) ii) Soviet Union through 1990 (prior to the secession of multiple former Soviet Republics and the new Russian Federation) iii) Yugoslavia through 1991 (prior to the independence of Bosnia, Croatia, Slovenia, and Macedonia)
