Economic growth refers to the steady increase in a nation's production capacity and national income over time. It is driven by advancing technology and the adjustments needed to effectively utilize new innovations. Economic growth can occur through improving existing inputs or increasing factor endowments, and should improve economic welfare. Economic development is a multidimensional process involving systemic reorganization and reorientation to quantitatively change economic wants, goods, incentives and institutions. It aims to make people self-sufficient and is defined as a long-term increase in real per capita income accompanied by structural and institutional changes. While economic growth expands the system, economic development leads to structural transformation through both increased output and changes to production and distribution arrangements.
