The Open Budgets Portal is the first effort to create a one-stop shop for budget data worldwide with the hope of bringing visibility to countries’ efforts in this field, facilitating access and promoting use of spending data, and motivating other countries into action. The purpose of the BOOST project is to enhance the transparency and efficiency of public spending across the globe by improving access to government expenditure data and linking spending to relevant results. The BOOST team has collected and processed detailed government expenditure data from more than a dozen countries, creating easy-to-use databases that have been employed by World Bank researchers on a variety of projects.
