Indices and Surveys

Indices and surveys are tools used to measure and track information about groups, economies, or industries. An index summarizes complex data into a single score, showing trends over time—like the stock market index indicating overall market performance. Surveys gather opinions or facts directly from people or organizations, providing insights into behaviors, preferences, or conditions. Both help policymakers, businesses, and researchers understand patterns, make decisions, and monitor progress. While indices offer a quick snapshot of broad changes, surveys provide detailed, specific data from sources directly involved.
