Development is a multidimensional process that advances social, cultural, and political aspects in addition to improving the economic outlook. Even so, around 70% of India’s labour force is still employed in the primary sector. The gross domestic product (GDP) of the nation was historically dominated by the primary sector before independence. But, even though most workers still depend on it for their living, its share of GDP has decreased over time. The industrial sector in Assam has been expanding gradually over time. A state’s overall development depends on advancements in its primary, secondary, and service sectors. Given the growing contributions of the secondary and service industries, it is imperative to assess their development over the years. The development of any state necessitates growth across all three sectors: primary, secondary, and service. With the contributions of the secondary and service sectors steadily increasing over time, it is essential to evaluate their progress. This study focuses on analyzing the growth of Assam’s industrial sector, utilizing indices to measure the level of development.
