Understanding Quality of Life Indexes

The Quality of Life Index estimates the overall quality of life in a city or country, considering factors such as purchasing power, pollution, housing affordability, cost of living, safety, healthcare quality, commute times, and climate. A higher index value indicates a better quality of life.

This index is based on data and user surveys collected by Numbeo, reflecting the perceptions and experiences of website visitors. Numbeo strives to provide accurate and up-to-date information by filtering out potential spam and ensuring a sufficient number of contributors for each location.

The index is calculated using an empirical formula that assigns weights to each factor based on its importance. While the specific formula may vary over time, it consistently combines the collected data to produce a numerical representation of quality of life.

The Quality of Life Index (higher is better) is an estimation of the overall quality of life by using an empirical formula that takes into account the following factors:

• Purchasing Power Index (higher is better)
• Pollution Index (lower is better)
• House Price to Income Ratio (lower is better)
• Cost of Living Index (lower is better)
• Safety Index (higher is better)
• Health Care Index (higher is better)
• Traffic Commute Time Index (lower is better)
• Climate Index (higher is better)

Current formula (written in Java programming language)*:

index.main = Math.max(0, 100 + purchasingPowerInclRentIndex / 2.5 - (housePriceToIncomeRatio * 1.0) - costOfLivingIndex / 10 + safetyIndex / 2.0 + healthIndex / 2.5 - trafficTimeIndex / 2.0 - pollutionIndex * 2.0 / 3.0 + climateIndex / 3.0);
