Disease Prevention Maps

Facebook Disease Prevention Maps are designed to help public health organizations close gaps in understanding where people live, how people are moving, and the state of their cellular connectivity, in order to improve the effectiveness of health campaigns and epidemic response. These datasets, when combined with epidemiological information from health systems, assist nonprofits in reaching vulnerable communities more effectively and in better understanding the pathways of disease outbreaks that are spread by human-to-human contact.



Facebook's High Resolution Population Density Maps aren't built using Facebook data and instead rely on combining the power of machine vision AI with satellite imagery from Maxar and census information from countries, which are already anonymized and de-identified data sources. Maps that use Facebook data, like Movement and Network Coverage, also include only de-identified and aggregated data from the Facebook platform.

Global Reach

Facebook's Disease Prevention Maps are global in reach. Our Population Density Maps are made from global satellite images and are being released worldwide. Movement Maps and Network Coverage Maps are also derived from Facebook data that is global in nature.

Demographic Estimates

Our Disease Prevention Maps include high-resolution maps that estimate not only the number of people living within 30-meter grid tiles, but also provide insights on demographics, including the number of children under five, the number of women of reproductive age, as well as young and elderly populations, at unprecedentedly high resolutions.

One of the most important pieces of information we need to respond to epidemics is where people are moving. This kind of data can be integrated into our epidemiological models to help us estimate how quickly a disease might spread, and where to put resources to contain it.”

Who Uses Disease Prevention Maps

International agencies

International agencies and UN organizations like UNICEF and the International Medical Corps can use the demographic estimates from our high resolution population density maps to better plan health commodity distributions such as those that take place on vaccination days or during national bed-net distributions.

Universities and researchers

Researchers and universities can combine information from health systems with aggregated and anonymous Facebook movement data to glean insights about where the next case of cholera or drug-resistant malaria is likely to occur.


Facebook Disease Prevention Maps show where people live, how people are moving, and whether they have connectivity.

Check out our high resolution population density maps, including demographic estimates, available for download on the United Nations Office for the Coordination of Humanitarian Affairs (OCHA)’s Humanitarian Data Exchange. Each country-level dataset contains the demographic estimates. If you're interested in working with movement or network coverage maps, please email diseaseprevmaps@fb.com.
