205 Science Research


Science research is measured here as the number of scientific papers that have been published in the subjects of physics, biology, chemistry, mathematics, clinical medicine, biomedical research, engineering, technology, and earth and space sciences, in 2001. Papers published are assigned to territories according to the author’s address, rather than the territory in which that journal is published. If a paper is authored by researchers in two different territories, then each territory is counted as having ‘half’ of this publication. Multiple authored papers are similarly divided up according to the ratio of authors to territories. Nearly two thirds of a million papers were published in enumerated science journals in 2001, which is 1 paper for every 10,000 people living in the world. In Western Europe, North America and Japan, the average is about 5 papers for every 10,000 people.

Data sources

The source of this data is the World Bank’s 2005 World Development Indicators, in the series on Scientific and technical journal articles (IP.JRN.ARTC.SC). The underlying source of this data is the National Science Foundation’s Science and Engineering Indicators. Where no figures are given missing values are shown as #N/A; counts are then estimated from combining regional averages along with territorial populations. Regional rates for Central Africa were estimated by halving the rate in Southeastern Africa, due to a lack of data for this region.

Excel sheets

Below is an explanation of each of the columns in the excel file:

Column A = Unique numerical territory (see 001).

Column B = Region and territory names (see 001).

Column C = Region code (see 001).

Column D = The ISO 3 code, or ISO ALPHA-3 (see 001).

Column E = Number of scientific papers published per year, in 2001. The data used here is taken from the source data sheet. Where data for 2001 is missing, the most recent year with data is used. Where there is no data the regional average figure for the number of science papers published per million people living there (Column F) is multiplied by the population in millions in 2002 (Column G) to produce an estimate of the number of science papers published. See ‘Data sources’ for information about regional rates for Central Africa .

Column F = Number of science papers published per year, per million people, in 2001. To calculate this, the number of science papers published per year, in 2001 (Column E) is divided by the population in millions, 2002 (Column G). (F = E / G).

Column G = Population in millions, 2002. See technical notes 002, Total Population.
