The data for “Children per woman (total fertility)” has been updated to cover 195 countries from 1800-2008. It is now possible to see the entire “demographic transition” that most countries have followed: going from many children and short lives, too few children and long lives.
A new data set on the HIV epidemics in each country since 1979 is now available in Gapminder World. The dataset is an expansion of the excellent UNAIDS data, and illustrates several interesting points.
Here is a moving graph with the percent adults infected with HIV in each country plotted against the GDP per capita. The size of the bubbles shows the number of people infected with HIV in each country (not the total population, as is usual in the Gapminder graphs). Click Play to see the epidemic from 1979 to 2007, and to see new surprising trends.
At the new documentation page you will find the documentation for the indicators compiled by Gapminder, including population. There you can also download an Excel-file that includes not only all the data, but also information on sources and estimation methods for each observation.
To the extent possible we have also used this information to give each observation one of these “data quality ratings”:
- Very Poor data quality – the population figure is based on guesstimates or rough extrapolations
- Poor data quality
- Fair data quality
- Good data quality
- Very Good data quality – the population figure is based on a rigourous census or equivalent
