Dataset
The dataset provides a global assessment of land, population, built-up area and cropland exposure to coastal flooding for different return periods. Exposure indicators to coastal flooding have been prepared by the Organisation for Economic Co-operation and Development (OECD). Please see the <a href="https://doi.org/10.1787/da074cb6-en">working paper</a> for a more complete description of the methods.
<br><br>The dataset spans the period 2000-2020 depending on data availability and is based on coastal flood hazard maps with a 10-, 25-, 50- and 100-year return period. A return period is the average or estimated time that a specific hazard is likely to recur. The dataset has a global geographic coverage on the 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.
