Is data before 1970 really useful for that purpose?

For infrastructure projects, it’s not as if one could procure data somewhere else than in the past. Time moves a lot slower for anything that involves masses of steel and concrete at country level. You extrapolate from historical data because as imperfect as it is it’s way better than pure guesswork.

(also it is very common to re-analyze historical data with new models to check their accuracy).
