Indicators are measurable factors that help assess the performance or condition of a specific area, such as the economy, health, or environment. They provide valuable information that can guide decision-making and policy development. For example, GDP is an economic indicator that reflects a country's overall economic activity. In health, indicators like life expectancy or infant mortality rate help evaluate the well-being of a population. Environmental indicators, such as air quality index or biodiversity levels, measure the health of ecosystems. By analyzing these indicators, stakeholders can identify trends, challenges, and opportunities for improvement.
