health indicator
{{Short description|Measure of quality of health, or magnitude of public health change caused by actions}}
Health indicators are quantifiable characteristics of a population which researchers use as supporting evidence for describing the health of a population. Typically, researchers will use a survey methodology to gather information about a population sample, use statistics in an attempt to generalize the information collected to the entire population, and then use the statistical analysis to make a statement about the health of the population.{{Cite book |last=Skolnik |first=Richard L. |url=https://www.worldcat.org/oclc/1126251416 |title=Global health 101 |date=2021 |isbn=978-1-284-14539-7 |edition=4th |location=Burlington, MA |oclc=1126251416}} Health indicators are often used by governments to guide health care policy or to make goals for improving population health.
Characteristics
A health indicator which will be used internationally to describe global health should have the following characteristics:
- It should be defined in such a way that it can be measured uniformly internationally.{{Cite journal | last1 = Larson | first1 = C. | last2 = Mercer | first2 = A. | title = Global health indicators: An overview | doi = 10.1503/cmaj.1021409 | journal = Canadian Medical Association Journal | volume = 171 | issue = 10 | pages = 1199–1200 | year = 2004 | pmid = 15534313| pmc =524951 }}
- It must have statistical validity.
- The indicator must be data which can feasibly be collected in a reasonable amount of time.
- The analysis of the data must result in a recommendation on which people can make changes to improve health

Applications
Health indicators are commonly used to make large-scale or community health-related decisions.{{Cite book |last=Culyer |first=Anthony |url=https://www.degruyter.com/document/doi/10.3138/9781442653412/html |title=Measuring Health: Lessons for Ontario |date=1978-12-31 |publisher=University of Toronto Press |isbn=978-1-4426-5341-2 |doi=10.3138/9781442653412}} By describing the current health of a population, the areas that need improvement become evident, and policy-makers and health professionals can work to fill these gaps.{{Cite web |date=2022 |title=Health Indicators: Conceptual and Operational Considerations |url=https://www3.paho.org/hq/index.php?option=com_docman&view=download&category_slug=health-analysis-metrics-evidence-9907&alias=45249-health-indicators-conceptual-operational-considerations-249&Itemid=270&lang=pt |website=Pan American Health Organization}} Once interventions are put in place to try to improve the health of a population, health indicators can then be used to evaluate the success of the intervention.
Additionally, health indicators can highlight health disparities in a population. Differences in health indicators among genders, races, ethnic groups, socioeconomic classes, and other groups can be used to guide policy and interventions that will bring health equity in the future.
Health indicators are used by many institutions, including international organizations such as the United Nations and World Health Organization (WHO).{{Cite web |last=World Health Organization |date=2018 |title=2018 Global Reference List of 100 Core Health Indicators |url=https://score.tools.who.int/fileadmin/uploads/score/Documents/Enable_data_use_for_policy_and_action/100_Core_Health_Indicators_2018.pdf |website=World Health Organization}}{{Cite book |date=2020-03-05 |title=Leading Health Indicators 2030 |url=http://dx.doi.org/10.17226/25682 |doi=10.17226/25682|pmid=32200597 |isbn=978-0-309-67187-3 |s2cid=240828832 }} They are also used by smaller-scale community health organizations, hospitals, and other medical and public health organizations such as the Center for Disease Control (CDC), National Institute of Health (NIH), [http://www.achap.org/ The African Comprehensive HIV/AIDS Partnerships] (ACHAP), and [https://www.globalallianceafrica.org/ Global Alliance for Africa].{{Cite web |title=Resources on African Health and Diseases |url=https://www.africa.upenn.edu/health/ngos_org.htm |access-date=2022-11-30 |website=www.africa.upenn.edu}}
