About this Video
It was the last 200 years that changed the world. In 1809 all countries of the world had a life expectancy under 40 years and an income per person less than 3000 dollar per year. Since then the world has changed but it was not until after the second world war that most countries started to improve.
For the first time, Gapminder can now visualize change in life expectancy and income per person over the last two centuries. In this Gapminder video, Hans Rosling shows you how all the countries of the world have developed since 1809 – 200 years ago.
The interactive animations and corresponding documentation are freely available at www.gapminder.org/world.
We have made an update of the indicator Life expectancy at birth. To see this indicator together with Income per capita, follow this link.
The biggest change is that we now show this indicator for 155 countries back to 1800, although in most cases, the early estimates are based on a very rough model. This full dataset is not suitable for statistical analysis. Please consult the documentation for information about sources and data quality. A spreadsheet with detailed source information will be added later.
You can also see some tentative information about data quality in the graph, look for this under “For advanced users” -> “Data quality”, or use this link. Red is “very poor quality data” while blue is “very good quality data”. Read more about our data quality ranking in this previous blogpost.
Gapminder World now incorporates the latest update on carbon dioxide emissions from burning fossil fuels. This update adds more recent data and makes some corrections for earlier years. Data are now available from 1751-2005.
See this example graph which shows CO2 emissions per person against income per person, with the bubble size representing total CO2 emissions.
