Supporting the argument, since progress keeps following the trend.
> life expectancy growth accelerated from ~2000 and is slowing down a bit again
Slight waviness superimposed on the overall trend.
> how is GDP per capita, an important metric, “a bit of a exception”
GDP per capita had a trend reversal in 2000, unlike the other metrics.
> annual GDP growth rate does seem a lot more steady since 2004
Most likely a change in methodology that gives less noisy estimates.
Two other less important and less immediate metrics. The “exception” easily outweigh them both.
That one takes off in 1993, about a decade before GDP exploded. Maybe the secret to Ethiopia's growth is just that the population became educated enough to do something useful with the money invested by foreign entities?
So, how is GDP per capita, an important metric, “a bit of a exception” among two other random stats (one of which even accelerated)?
Meanwhile, annual GDP growth rate does seem a lot more steady since 2004: https://data.worldbank.org/indicator/NY.GDP.MKTP.KD.ZG?locat...
