To divide decimals from whole number a full point (.) is used.
The tables do not include countries for which there were insufficient data.
Numbers displayed in the tables might be slightly different from those obtained from FAOSTAT and the World Development Indicators because of rounding.

FAO's estimates of the prevalence of undernourishment are based on calculations of the amount of food available in each country (national dietary energy supply or DES) and a measure of inequality in distribution derived from household income or expenditure surveys.
Although not listed separately, provisional estimates for Afghanistan, Iraq, Papua New Guinea and Somalia have been included in the relevant regional aggregates.
Eritrea and Ethiopia were not separate entities in 1990-1992, but estimates of the number and proportion of undernourished in the former Ethiopia PDR are included in regional and subregional aggregates for that period.
To denote a proportion of less than 2.5 percent undernourished a dash (-) is used.
Per capita supplies in terms of product weight are derived from the total supplies available for human consumption (i.e. food) by dividing the quantities of food by the total population actually partaking of the food supplies during the reference period. Dietary energy supply is weighted by the total population.

The growth rates refer to the level of change of the aggregate volume of production. Production quantities of each commodity are weighted by 1999-2001 average international commodity prices and summed for each year.

The total population usually refers to the present-in-area (de facto) population, which includes all persons physically present within the current geographical boundaries of countries at the mid-point of the reference period.
Usually the urban area is defined and the residual from the total population is taken as rural. In practice, the criteria adopted for distinguishing between urban and rural areas vary among countries.
The agricultural population is defined as all persons depending for their livelihood on agriculture, hunting, fishing or forestry. This estimate comprises all persons actively engaged in agriculture and their non-working dependants.
This refers to the number of all employed and unemployed persons (including those seeking work for the first time).
The economically active population in agriculture is that part of the economically active population engaged in or seeking work in agriculture, hunting, fishing or forestry.

Total area excluding area under inland water bodies.
Land under natural or planted stands of trees, whether productive or not.
The sum of area under arable land, permanent crops and permanent pastures.
Land under temporary crops (double-cropped areas are counted only once), temporary meadows for mowing or pasture, land under market- and kitchen-gardens and land temporarily fallow (less than five years).
Land cultivated with crops that occupy the land for long periods and need not be replanted after each harvest.
Land used permanently (five years or more) for herbaceous forage crops, either cultivated or growing wild (wild prairie or grazing land).
Data on irrigation relate to areas equipped to provide water to the crops.
Data refer to total fertilizer use. The total estimates are obtained by adding the volumes of nitrogenous, phosphate and potash fertilizers expressed in terms of plant nutrients (N, P2O5 and K2O, respectively).

Data refer to the total merchandise trade. In general, export values are f.o.b. (free on board) and import values are c.i.f. (cost, insurance and freight).
Data refer to agriculture in the narrow sense, excluding fishery and forestry products.
Data refer to food and animals.
The agriculture, value added (percentage of GDP), is derived from World Bank national accounts data, and OECD National Account data files. Agriculture includes forestry, fishing and hunting, as well as cultivation of crops and livestock production.
Agricultural exports relative to agricultural GDP was weighted by agriculture, value added.

Weighting: GNP per capita (current US$), GDP per capita (annual percentage growth) and GDP per capita, PPP (current international $) were weighted by the total population. GDP (annual percentage growth) and agriculture, value added (percentage of GDP), were weighted by GDP (constant 2000 US$). Agriculture, value added (annual percentage growth), was weighted by agriculture, value added (constant 2000 US$). Agriculture, value added per worker, was weighted by economic active population in agriculture.
National poverty rate is the percentage of the population living below the national poverty line. National estimates are based on population-weighted subgroup estimates from household surveys.
GNP per capita is the gross national income, converted to US dollars using the World Bank Atlas method, divided by the mid-year population.
Annual percentage growth rate of GDP at market prices based on constant local currency. Aggregates are based on constant 2000 US dollars.
Annual percentage growth rate of GDP per capita based on constant local currency. GDP per capita is the GDP divided by mid-year population.
GDP per capita based on purchasing power parity (PPP). PPP GDP is gross domestic product converted to international dollars using purchasing power parity rates. An international dollar has the same purchasing power over GDP as the US dollar has in the United States of America.
Agriculture, value added per worker, is a measure of agricultural productivity. Value added in agriculture measures the output of the agriculture sector less the value of intermediate inputs. Agriculture comprises value added from forestry, hunting and fishing as well as cultivation of crops and livestock production.
Data are in constant 2000 US dollars. Dollar figures for GDP are converted from domestic currencies using 2000 official exchange rates.

Total factor productivity (TFP) measures the quantity of output divided by a measure of the quantity of inputs used. The approach taken here is to apply data envelopment analysis (DEA) methods to output and input data obtained from FAOSTAT to estimate a Malmquist index of TFP (Malmquist, 1953). The data cover the periods 1961-80 and 1981-2000. The resulting change in total productivity index can be disaggregated into a technology component and a technical efficiency component. A distinct advantage of the Malmquist DEA method is that no information on input prices is required. The data used are as follows: Output is net agricultural production, i.e. excluding seed and feed, in constant (1989-91) “international dollars”; Inputs are: Land: arable and land under permanent crops; Labour: total population economically active in agriculture; Fertilizer: total consumption (in nutrient-equivalent terms) of nitrogen, potash and phosphates; Livestock: the weighted sum of camels, buffalo, horses, cattle, asses, pigs, sheep, goats and poultry (using the weights suggested by Hayami and Ruttan, 1985); Physical capita: number of tractors in use. We also included the proportion of arable and permanent cropland that is irrigated as well as the ratio of land that is arable and under permanent crops to agricultural area (which also includes permanent pastures).
Data for Ethiopia and Eritrea start in 1993 instead of 1981.
Data for China do not include data for Hong Kong Special Administrative Region; Macao Special Administrative Region or Taiwan Province of China, unless otherwise noted.
Data are shown for Belgium and Luxembourg separately whenever possible, but in most cases before 2000 the data are aggregated in Belgium/Luxembourg.
Data are shown whenever possible for the individual countries formed from the Ethiopia PDR - Eritrea and Ethiopia. Data for the years prior to 1992 are shown under Ethiopia PDR.
Data for Yemen refer to that country from 1990 onward; data for previous years refer to aggregated data of the former People's Democratic Republic of Yemen and the former Yemen Arab Republic unless otherwise noted.
South Africa is included in sub-Saharan Africa and not in the developed countries.
