Russia—moved from the upper-middle-income to the high-income category:

Economic activity in Russia was influenced by a large increase in military related activity in 2023, while growth was also boosted by a rebound in trade (+6.8%), the financial sector (+8.7%), and construction (+6.6%). These factors led to increases in both real (3.6%) and nominal (10.9%) GDP, and Russia’s Atlas GNI per capita grew by 11.2%.
