GDP growth rate measures the rate at which a country's gross domestic product (GDP) expands or contracts over a specific period. It indicates the overall growth or contraction of an economy. A positive GDP growth rate reflects economic expansion, increased production of goods and services, and higher living standards. Conversely, a negative growth rate signifies an economic contraction or recession. GDP growth rate is influenced by factors such as consumer spending, business investment, government expenditure, and net exports. It is a key indicator used to assess the health and performance of an economy.
