ENCE coordinates UN Regional Hub for Big Data in Brazil

The result of a partnership between the IBGE and the UN Statistics Division, the UN Big Data Regional Hub in Brazil was launched in November 2021 in the 11th Statistical Conference for the Americas, carried out by the (Economic Commission for Latin America and the Caribbean (ECLAC). The Hub is based at the National School of Statistical Sciences (ENCE), an academic area of the IBGE, which coordinates efforts and contributions from different fields of the Institute to support activities within the Regional Hub.

The project focuses on the advance in the use of big data use to improve the production of official statistics, so as to promote the sharing of knowledge and of innovative initiatives in Latin America and the Caribbean. Other hubs besides Brazil are United Arab Emirates, Rwanda, Indonesia and China.
