Macro-economic methodology

Data sources

One of the most comprehensive datasets on macro-economic indicators is produced by the World Bank. Data in the national currency is converted into a common currency, the United States Dollar, in order to allow comparison of indicators and aggregation at regional and global levels. This is the principal source of data and is used as the base-line. For concepts and definitions of primary indicators, refer to the World Bank World Development Indicators, 2002.

The indicators are updated once a year, when the World Development Indicators CD Rom is made available (usually mid-year). Secondary data sources include: UN Statistics Division and its regional bodies (ESCAP, ESCWA, ECE, ECLAC); Development Banks (African, Asian, Caribbean); European Commission; OECD; Country Statistical Yearbooks and other country sources. Where feasible, FAO makes estimates of any missing data for reporting at regional and global levels.

- Agricultural GDP per hectare of agricultural land

Primary Indicators used for Derived Indicators and Country Group Aggregates

- Agriculture, value added (constant 1995 US$)
- GDP (constant 1995 US$)
- GNI, Atlas method (current US$)
- Gross capital formation (current US$)
- Gross value added at factor cost (current US$)
- Land use, agricultural (hectares)
- Population, agricultural
- Population, total

Data can be provided for any of the above three groups of indicators, at the country or aggregate level.
