Life Expectancy & Quality of Life


Life expectancy or quality of life for communities or populations.


Enhancement of well-being among community members is a key goal of clinical and translational research. Increases in life expectancy and quality of life are frequently used to assess community health.


Advice from authors on searching for information:

Without specific analyses, it is challenging to attribute changes in quality of life or life expectancy of a population to dissemination and implementation of a specific clinical and translational research project. Researchers may want to consult with domain specific experts.

Resources & Data

Organizations, repositories, websites, and other sources where you can find more information:


Missouri Department of Health and Senior Services
This MDHSS site provides information on health assessment and intervention planning. Data on life expectancy for Missouri’s 115 counties as well as other data sets are also available for surveillance purposes.


CDC- National Center for Health Statistics
This CDC site provides life expectancy data and other data sets for the United States.

CDC’s Health-Related Quality of Life
This CDC site provides information about the health-related quality of life (HRQOL) questionnaire and links to data.

RAND Health Surveys
RAND Health provides several quality of life surveys available without charge.

The WHOQOL-BREF is a quality of life scale developed through the World Health Organization.

Data Limitations

Challenges you may encounter while searching for information:

Access to self-reported researcher or administrative/in-house data may be required to locate documentation. Relevance of case studies and indicators may be affected by whether the work is global, national, state, or local.
