• Global Financial Inclusion (Global Findex) Database (2011+). Financial inclusion is a cornerstone of development, and since 2011, the Global Findex Database has been the definitive source of data on the ways in which adults around the world use financial services, from payments to savings and borrowing, and manage financial events such as a major expense or a loss of income. Results from the first survey were published in 2011 and have been followed by subsequent survey results from 2014 and in 2017. The 2021 edition, based on nationally representative surveys of about 128,000 adults in 123 economies during the COVID-19 pandemic, contains updated indicators on access to and use of formal and informal financial services, including on the use of cards, mobile phones, and the internet to make and receive digital payments—including the adoption of digital merchant and utility payments during the pandemic—and offers insights into the behaviors that enable financial resilience. The data also identify gaps in access to and usage of financial services by women and poor adults.
