The World Development Indicators, a by-product of the World Bank's statistical and analytical work,
provide information on the main features of social and economic development. Most of the data collected by the World Bank are on its developing member countries. Because comparable data for
industrial market economies are readily available, these are also included in the indicators. Data for
nonmarket economies, a few of which are members of the World Bank, are included if available in
a comparable form. Every effort has been made to standardize concepts, definitions, coverage, timing, and other characteristics of the basic data to ensure the greatest possible degree of comparability. Nevertheless, care must be taken in how the indicators are interpreted. Although the statistics are drawn from sources generally considered the most authoritative and reliable, many of them are subject to considerable margins of error. In addition, variations in national statistical practices mean that most data are not strictly comparable. The data should thus be construed only as indicating trends and characterizing major differences among economies. The indicators in Table 1 give a summary profile
of the economies. The data in the other tables fall into the following broad areas: national accounts,
agriculture, industry, energy, external trade, external debt, aid flows, other external transactions,
demography, labor force, urbanization, social indicators, central government finances, and income
distribution. The table on central government expenditure is an expanded version of an earlier
table, and is complemented by a new table on central government current revenue. Most of the information used in computing the indicators was drawn from the data files and publications
of the World Bank, the International Monetary Fund, and the United Nations and its specialized
agencies. For ease of reference, ratios and rates of growth are shown; absolute values are reported only in a few instances. Most growth rates were calculated for two periods: 1960-70 and 1970-82, or 1970-81 if
data for 1982 were not available. All growth rates same order is used in all tables. The alphabetical
list in the key shows the reference number of each economy; italics indicate those economies placed
at the end of a group due to the unavailability of GNP per capita figures. Countries with populations
of less than a million are not reported in the tables, largely for lack of comprehensive data. The technical note to Table I shows some basic indicators for 34 small countries that are members of the
United Nations, the World Bank, or both. Summary measurestotals, median values, or weighted averageswere calculated for the economy groups only if data were adequate and meaningful
statistics could be obtained. Because China and India heavily influence the overall summary
are in constant prices and were computed, unless
noted otherwise, by using the least-squares
method. Because this method takes all observations
in a period into account, the resulting growth
rates are not unduly influenced by exceptional values.
Table entries in italics indicate that they are for
years or periods other than those specified. All
dollar figures are US dollars, derived by applying
the official exchange rates, with the exception of
the GNP per capita figures, which are derived by
applying the World Bank Atlas method described
in the technical note to Table 1. Conversion of
national currency values in this manner results in
some inevitable distortions; the technical note to
Table 1 also discusses this problem.
Some of the differences between figures shown
in this year's and last year's editions reflect not
only updating but also revisions to historical
series.
The economies included in the World Development
Indicators are classified by GNP per capita.
This classification is useful in distinguishing economies
at different stages of development. Many of
the economies included are also classified by domi-'
nant characteristicsto distinguish oil importers
from oil exporters and to distinguish industrial
market from industrial nonmarket economies. The
groups used in the tables are 34 low-income developing
economies with a GNP per capita of less
than $410 in 1982, 60 middle-income developing
economies with a GNP per capita of $410 or more,
5 high-income oil exporters, 19 industrial market
economies, and 8 East European nonmarket economies.
Note that because of the paucity of data and
differences in the method of computing national
income, estimates of GNP per capita are available
only for those nonmarket economies that are members
of the World Bank.
The format of this edition generally follows that
used in previous years. An important difference,
however, is that economies for which no GNP per
capita figure can be calculated are listed in italics,
in alphabetical order, at the end of the appropriate
income groups. All other economies are listed by
group in ascending order of GNP per capita. Themeasures for the low-income economies, summary
