U don't need data my friend, you need to look at Russia as you would look at country from 19th century.

With war and sanctions, actually more money stays in the country as oligarchs cant go on and waste money as they did before. Don't be naive , what Russia can sustain not a country in a world can.

In Russia , as long as there is enough vodka ,bread , potatoes , oil and wood 60% of the population won't notice the change of life.
