Straight lines, S-bends, slides, and humps

Most of these charts use national income data; see Gapminder[3].

A few (the straight line on recreational spending,

the S-bend on vaccinations and fridges

, and the slide on fertility) use household data.

In each example, there are huge differences between countries on every level. Very few countries follow these lines exactly, but the lines show the general pattern of all countries over several decades.


This page is under construction. We are working on it (and a lot of other pages too). If you need this particular page urgently, you can always drop us a line, and we might be able to squeeze it to the top of our prio list…
