Identify where to search
Start by identifying organisations that might be collecting the types of data you are looking for.
- Governments - Most statistics are collected by national and subnational government agencies, e.g. the Australian Bureau of Statistics, the Office for National Statistics (UK).
- International organisations - Organisations and institutions such as the World Bank, the United Nations, and the Organisation for Economic Co-operation and Development (OECD) collect and collate statistics from different countries.
- National organisations - Many national organisations and research bodies collect statistics on particular areas of interest, e.g. the Australian Council for Educational Research, Diabetes Australia.
- Professional associations - Some professional bodies conduct research and publish survey findings, e.g. the Australian Institute of Management.
International statistics are dependent on the collection of data by national governments and other agencies, so the types, depth and dates of data are not always consistent between countries.
Collection of data within individual countries
- changes over time,
- may be inconsistent across states,
- and can be disrupted by events such as regime change and war.
