Write a short note on Perceived Environmental Quality Index.

The Perceived Environmental Quality Index (PEQI) is a measure used to assess individuals' subjective perceptions of their surrounding environment. It evaluates various aspects of environmental quality, including air and water quality, noise levels, green spaces, cleanliness, and safety. The PEQI is often based on surveys or questionnaires administered to residents or stakeholders living or working in a specific area. By capturing individuals' perceptions and experiences, the PEQI provides valuable insights into the quality of the built and natural environment from a user's perspective. Policymakers, urban planners, and environmental professionals use the PEQI to identify areas for improvement, prioritize interventions, and enhance the overall environmental quality of communities. Additionally, the PEQI complements objective measures of environmental quality, providing a more comprehensive understanding of people's experiences and preferences in their living environments.
