Reliable population data is crucial in the humanitarian sector for prioritizing life-saving activities. Finding a publicly available population density dataset used to be challenging, especially if you needed consistent global data. Making population data accessible helps organizations like the Humanitarian OpenStreetMap Team and the Canadian Red Cross identify blank spots on maps or gain more insights into local OSM communities when combined with other datasets. This led us to develop the Kontur Population dataset, which we visualized as a population density map.
World population density map
The world population density map shows the distribution of people across the globe, with higher population densities typically concentrated in urban areas and lower densities in rural areas.

Kontur population dataset
Grid system
Kontur Population dataset is represented by H3 hexagons with population counts at 400m resolution. We use the H3 grid instead of the common square grid because hexagons maintain equal distances between a hexagon’s center and the centers of its neighboring cells. This property greatly simplifies analysis and gradient smoothing.
Data sources
Population calculations are based on the Global Human Settlement Layer (GHSL) – a framework relying on a large set of sensors, including radar and optical public and commercial missions.
GHSL data is overlaid with Facebook population data (HRSL) where available.
Microsoft Building Footprint, Land Information New Zealand, and Copernicus Global Land Service data are used to improve distribution accuracy.
Improving data accuracy
Known artifacts of GHSL and HRSL datasets are constrained using OpenStreetMap data. The presence of buildings, or built-up areas, suggests human activity, which is often missed in Facebook’s Africa data. Quarries and big roads are marked as unpopulated, as they are often falsely detected as populated in GHSL. Lakes, rivers, glaciers, sands, forests, and other alike land uses are marked as unpopulated.
While the population total is accurate, extremely populated cells (i.e., 500,000 people in .25 km²) are spread out to neighboring cells to satisfy constraints. Non-integer population counts are rounded to the nearest whole number.
The latest version of Kontur Population is available at data.humdata.org.

Humanitarian mapping
The dataset was primarily designed to support visualization behind Disaster Ninja. The tool is actively used by humanitarian mappers to take action confidently based on data correlated with world population density. Read how data correlated with global population density helps support the rapid deployment of emergency mapping campaigns for Humanitarian OpenStreetMap Team.

Waste management optimization
Our team aimed to apply our geospatial expertise to address local environmental challenges. We teamed up with volunteers in Batumi to help them approach the problem of litter that pollutes streets, parks, rivers, and beaches within the city. We created a bivariate choropleth map to visualize the waste bin availability along with population density within one layer. Service data are used to improve distribution accuracy.
Commercial site selection
Using geospatial data analysis significantly reduces the time it takes to find the best location when starting a new business. Reliable population data is a crucial part of such analysis. Read how we used Machine Learning algorithms to detect building footprints from satellite imagery and create a custom population dataset for a site selection project in Abu Dhabi.
30DayMapChallenge
Population data is applicable for visualization and insight extraction in various domains. Kontur Population became one of the daily topics of #30DayMapChallenge on Twitter. Hundreds of participants use the data to create maps to visualize climate change, flood risk, water security, access to emergency services, and other topics.
Viral population density maps
If you’re interested in geodata and data visualization, you can’t help but notice worldwide population density maps going viral and getting hundreds of thousands of views on social media. Many enthusiasts use Kontur Population data to create such maps, which get noticed by media outlets like Colossal.
Building local population maps
Local population density maps are crucial for city planners and policymakers to make informed decisions about infrastructure, public services, and emergency management. Real estate professionals use these maps to identify trends and make informed decisions about property values and investments.
How to use
The Kontur Population Dataset is becoming increasingly popular and trusted, with over 5,300 downloads on HDX, where Kontur offers over 500 datasets in total.
The latest version of Kontur Population is available at United Nations Humanitarian Data Exchange (HDX). There are three resolution versions available to download:
