What is the share of service sector in the national income?

The share of the service sector in national income varies by country but has generally increased over the past few decades. In many developed economies, the service sector can account for over 70% of GDP, reflecting a shift from manufacturing to services such as finance, healthcare, and technology. In developing nations, this share is often lower but still growing as economies modernize and urbanize. Overall, the service sector has become a crucial component of national income across the globe.
