Not all datasets listed in the catalog are owned by the WBG. Data ownership and terms of use are determined by agreements between the parties responsible for creating and maintaining the dataset. Data ownership is an important consideration in the catalog, and is reflected in each dataset's metadata. The World Bank does not endorse or verify the content of datasets owned by other organizations. Our choice to list external datasets in our catalog depends on our assessment regarding the relevance of the datasets to issues pertinent to international development.
