  • As I said in the other place this article was posted: the source seems to be an online reader survey from t-online.be. That means the scientific value of this is pretty low. For decent surveys, you need a random sample. In this case, you need to be a visitor of t-online, and you decide for yourself that you want to participate. That’s already enough to skew results. Add to that that there’s a lot of online activism against Tesla (for obvious reasons), so the poll could have been partly hijacked. Such a low number of people who don’t care or haven’t heard about Tesla going rogue is not realistic anyway. There’s a lot of people who are weird, contrarian or simply avoid all news.






  • Basically all countries that started having some economic growth since 1950 will have this spike effect. The countries that were already rich had a slow population transition, the other ones a fast one. The short version of that story is that in the latter child mortality went down slowly, and in the the former it was a quick proces. People take some time to adapt to this new reality, which means that for a shirt period of time 10 of 10 children will grow up to have kids of their own. After a while, the amount of children goes down to 2 or less, and growth stops. In Europe, this lade population multiply by two or three, in North Africa for example it can be up to times five or more. And in modern societies, this kind of growth tends to concentrate in cities.
