Population Clock is an iOS tool for learning about geography and demographics.
Download app on iTunes
The project uses the most recent data from these two trusted sources:
Besides the iOS app, there are a few Python scripts to execute the following actions:
- Scrape the country descriptions and energy production from the World Factbook.
- Download the most recent indicators from World Databank using their JSON API (Some updates are quarterly and others yearly).
- Generate plist file with all indicators and descriptions to use with Xcode.
- With population growth data, create colored SVG map.
- Generate 8-bit greyscale map with one color per country. This allows us to identify which country was clicked by reading the color of the selected pixel.
Here is a list of the metrics displayed in the app. Some countries do not have all the data.
