The Trendalyzer and Gapminder World tools allow users to explore how statistics relating to various ecological and quality of life factors interact. Users are able to choose from internationally recognized data sets on development, quality of life and ecology, and view how these factors relate to one another over time and across geographic realms.
The Trendalyzer shows data until 2005 and Gapminder World also for the most recent years. Trendalyzer includes a multitude of ecological indicators, the Ecological Footprint as one of them along with carbon emissions, energy use, fossil fuel consumption and other factors. Users can can plot these factors against others such as literacy, mortality, income, and population to view trends and correlations.
Try tools yourself and see how useful they are for analyzing correlations between different data sets across time. Tools were created by Gapminder, a non-profit venture promoting sustainable global development by increased use and unserstanding of statistics and other information about social, economic and environmental development at local, national and global levels. Gapminder was recently acquired by Google.
