Which country has the best teeth in the world?

We have added a new indicator: “bad teeth per person” (you find it under “health” in the Gapminder World).

Here we have plotted “bad teeth per person” against “income per person”. Is dental problems worst in the richest or the poorest countries? There actually seem to be a tendency for the dental problems to be larger in the middle income countries, while the population in the richest and poorest countries have somewhat better teeth.

“Bad teeth per person” show how many decayed, missing or filled teeth an average 12 year old has in each country. The technical term of the indicator is DFMT for 12-years old and the data is taken from the WHO. We have unfortunatly only data for one year. Note that the data in many cases are actually based on estimates for earlier years.

There are some interesting discussions concerning this indicator over at Chris Blattman’s blog as well as at  the meaningfullness of little things.

Who has the oil, and who uses it?

We have added 24 new data series with data on consumption and production of oil, natural gas, coal and other energy sources.The source of these data is BP’s World Statistical Review 2008.

We think these are fascinating data: they show you who has the oil and who uses it, the remarkable close relationship between energy consumption and income, and many other interesting relationships.

Life expectancy expanded

We have used some additional sources to add more data to the indicator “Life expectancy at birth”. You can now follow several European countries from the 19th century and India, Sri Lanka and USA from the beginning of the 20th century. Data for Taiwan, which has previously been missing for this indicator, is now available from 1928. See Taiwan almost catch up with Australia, in both life expectancy and income. Or follow Sweden for 206 years of health history, with decreasing infant mortality and increasing life expectancy, as income also increases (income is seen as bubble color in this example).
