Countries in Stage 3 (often referred to as 'Industrial stage')

Countries in Stage 3, often called the "Industrial stage," have shifted from primarily agricultural economies to industrialized ones. During this phase, urbanization increases as people move to cities for factory jobs. There is also significant growth in infrastructure, such as transportation and communication systems. Birth rates begin to decline due to changes in social norms and increased access to education and healthcare. Economic activities diversify, with manufacturing and services playing major roles. Examples of countries in this stage include Brazil and India, where industrial growth fosters economic development and improves living standards, although challenges like pollution can arise.
