Analysis
In 2023, exposure to extreme precipitation — annual precipitation change in American Samoa stood at -12.53 Millimetres per year.
Compared with earlier readings it is up 96.7% on the previous year and down 112.5% over ten years.
Over the whole period, exposure to extreme precipitation — annual precipitation change in American Samoa peaked at 1,298 Millimetres per year in 2020 and was at its lowest, -761.52 Millimetres per year, in 1983.
That places American Samoa 155th out of 263 countries with data for 2023, putting it in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.

About this data
The dataset provides a global assessment of changes in average precipitation by providing the precipitation anomaly and provides a global assessment of extreme precipitation through the use of two precipitation indices, i.e. very heavy precipitation days and frequency of extreme precipitation events. Exposure indicators to extreme precipitation have been prepared jointly by the Organisation for Economic Co-operation and Development (OECD) and the International Energy Agency (IEA). Please see the working paper for a more complete description of the methods. The datasets span the period 1979-2022, depending on data availability and are the result of the use of a variety of geospatial data sources as referenced in the Working Paper. The dataset has a global coverage on a national level; on the sub-national TL2 level (i.e. large subnational regions) results are reported for all OECD countries as well as for Argentina, Brazil, China, India, Indonesia and South Africa. A number of aggregates are included: Euro area, European Union, Advanced economies, Emerging market economies, G7, G20, OECD, OECD Europe, OECD Asia Oceania, OECD Americas and the LAC region.
