Vital statistics
Vital statistics are the statistical outputs of a demographic system that reflect the major life events of people, namely birth, death, and marriage. These statistics are derived from a universal, mandatory registration system that records the occurrence and characteristics of these events. The system is usually operated within a legal framework that requires the events to be reported as they occur.
Births[edit]
The birth rate is a vital statistic that measures the number of births in a population. It is usually expressed as the number of live births per 1,000 population in a year. The birth rate is an important indicator of population growth and fertility.
Deaths[edit]
The death rate is another vital statistic that measures the number of deaths in a population. It is usually expressed as the number of deaths per 1,000 population in a year. The death rate is an important indicator of mortality and life expectancy.
Marriages[edit]
The marriage rate is a vital statistic that measures the number of marriages in a population. It is usually expressed as the number of marriages per 1,000 population in a year. The marriage rate is an important indicator of social structure and family formation.
Uses[edit]
Vital statistics are used in a variety of ways. They are used by governments to plan services and policies, by researchers to study trends and patterns, and by individuals to understand their society and its changes.
