Demographics Data

Facebook publishes detailed population data with demographic information under its initiative FACEBOOK Data for Good. It is one of the most granular data sets about the worldwide population using official census and Facebook data combined with image recognition.

The raw data is aggregated in 30x30 m squares which we transform to H3 bins at resolution 11. For each bin there is the statistical population value for:

• Total

• Female

• Male

• Children under 5

• Youth 15 - 24

• Elderly 60 plus

• Women of reproductive age 15 - 49
