Démographie et révolution des données

In 2014, the William and Flora Hewlett Foundation approached the IUSSP with a project to bring IUSSP members into ongoing discussions about the need for a data revolution to accompany the post-2015 development agenda and monitor progress towards a new set of goals and indicators, the Sustainable Development Goals, which will replace the MDGs in 2015. In collaboration with the Population Association of America (PAA) and with the assistance of the Overseas Development Institute (ODI), the IUSSP organized or participated in a number of activities to enable demographers to contribute their skills to the Data Revolution.


The list of activities is provided here in reverse chronological order.


For those of you interested in learning more about the Data Revolution, a number of background documents are provided below and links to websites related to the Data Revolution are provided in the right-hand column.
