Data indicators refer to statistical measures that provide insight into a particular phenomenon or situation. They are used to track changes, identify trends and patterns, and make informed decisions based on the data collected. Data indicators can be quantitative (numerical) or qualitative (non-numerical), depending on the type of information being measured. For example, common quantitative indicators include measures such as GDP per capita, unemployment rate, and literacy rates, while qualitative indicators may include things like crime rates, pollution levels, or access to healthcare services. Overall, data indicators serve as a tool for understanding complex social, economic, or environmental issues through the analysis of numerical or descriptive information.
