Since the Renaissance, Europe has had a major influence in culture, economics and social movements in the world. The most significant inventions had their origins in the Western world, primarily Europe and the United States.[202][203] Approximately 70 million Europeans died through war, violence and famine between 1914 and 1945.[204] Some current and past issues in European demographics have included religious emigration, race relations, economic immigration, a declining birth rate and an ageing population.
