DATASETS

High Resolution Population Density Maps

Accurate population density data is critical for delivery of social services. Meta has built the world’s most accurate population maps using satellite imagery and census data.

Kinshasa - Population Density
Our partner mWater’s Population Density visualization shows how many people live within one kilometer of a water point and how many people are within ten kilometers of a health facility.

Key Features

High resolution
Working with the Center for International Earth Science Information Network (CIESIN), we use artificial intelligence to identify buildings from satellite imagery and estimate population at a 30 meter resolution.
Demographic breakdowns
In addition to total population density, we release estimates for women, men, youth, children, women of reproductive age, and the elderly at a 30 meter resolution.
Publicly available
These maps are publicly available for 160+ countries and territories around the world, and can be downloaded from Humanitarian Data Exchange or Amazon Web Services.

Methodology

Step 1: Model population growth with CIESIN
CIESEN records every census and uses that information to model population growth by country and at subnational levels.
Step 2: Calculate connectedness
With over three billion people using Meta services, this index provides the first comprehensive measure of social networks at an international level.
Step 3: Drop small counts and add noise
SCI publishes a nmber to show the probability of friendship between two areas, but no information on individual friendships. We use sampling, normalization, and differential privacy to protect privacy.
Step 4: Final sampling
SCI publishes a nmber to show the probability of friendship between two areas, but no information on individual friendships. We use sampling, normalization, and differential privacy to protect privacy.
