Human wellbeing can be measured through quantitative and qualitative indicators. Quantitative indicators such as life expectancy, infant mortality rate, and literacy rates provide objective data on factors like health and education. Qualitative indicators rely on subjective surveys to measure happiness, job satisfaction, and social relationships. Together these indicators give an overall view of a population's wellbeing. Wellbeing varies globally and is determined by access to necessities as well as wealth, which influences factors like healthcare, sanitation, and education. Measuring these indicators on local, national, and global scales can help governments and organizations assess and improve populations' quality of life.
