331 Telephone Lines 1990
This map shows the distribution of telephone mainlines, or telephone connections, in 1990. A telephone mainline is a single fixed telephone line going to a house irrespective of the number of telephones connected to that line. The importance of telephones is indicated by telephone mainlines and cellular subscribers combining to form an indicator for Millennium Development Goal 8.
The source of these data Is the United Nations Development Programme's 2004 Human Development Report, Table 12. The underlying source for these data Is the International Telecommunication Union (ITU). World Telecommunication Indicators Database, 7th edition. [see: http://www.itu.int/ITU-D/ict/publications/world/world.html]. March 2004
Data was missing for 27 territories. 15 values were estimated by projecting backwards from recorded telephone use in 2002. Simple use of regional averages is then limited to 12 territories that provided no data for 1990 and for 2002.

The quotation used to accompany this map is sourced from a keynote address by Dr. Pekka Tarjanne to ‘ The 21st Century Global Information Society’, in Jakarta on 12 th June, 1997 .

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 = Telephone mainlines in 1990, in millions. This is calculated by multiplying telephone mainlines in 1990 per 1000 people in 1990 (Column F) by the population in 1990 in millions (Column G) and dividing by 1000, to give the telephone mainlines in millions. (E = F * G * 0.001).
Column F = Telephone mainlines in 1990 per 1000 people in 1990. This is taken directly from the source data. Where data are missing, the regional average telephone mainlines per 1000 people is assumed.
Column G = Population in millions, for year 1990. For source data and derived estimates see 163, Wealth Year 1990.Column H = Telephone mainlines in 1990 per 1000 people in 1990. This is taken from the source data. Where data are missing ‘..’ is shown.
