Life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth, which can be defined in two ways: cohort life expectancy and period life expectancy. Life expectancy is an important indicator of a population's health and well-being. According to the World Health Organization (WHO), life expectancy is influenced by various factors. However, the exact causes and trends of life expectancy are reportedly complex and multifaceted.

Life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth, which can be defined in two ways: cohort life expectancy and period life expectancy. Cohort life expectancy is the mean length of life of a birth cohort, while period life expectancy is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year.

Life expectancy is calculated using demographic notation, where ex denotes the average life remaining at age x. This can be computed using various methods, including the cohort life expectancy method and the period life expectancy method. The cohort life expectancy method involves tracking a group of people born in the same year and calculating the average length of life, while the period life expectancy method involves calculating the average length of life based on the mortality rates observed at a given year.

The top causes of death in the United States in 2020 were heart disease, cancer, and chronic lower respiratory diseases. People with higher incomes and education levels tend to have higher life expectancy. Countries with higher GDP per capita tend to have higher life expectancy.

The World Health Organization (WHO) is a leading international organization that works to improve global health, including life expectancy. Other notable organizations include the National Institutes of Health (NIH), the American Cancer Society, and the American Heart Association.

Life expectancy has a significant cultural impact and influence on society. It is an important indicator of a population's health and well-being. The Oklahoma Native American tribes have a lower life expectancy than the general US population, due to factors such as limited access to healthcare and higher rates of poverty.

The United Nations has set a goal to reduce premature mortality from non-communicable diseases by 25% by 2025. The World Health Organization (WHO) has launched initiatives to improve life expectancy in developing countries.

There are several controversies and debates surrounding life expectancy, including the use of different methods to calculate life expectancy and the impact of various factors on life expectancy. Some argue that life expectancy is not a good indicator of health, as it does not take into account the quality of life.

The future outlook for life expectancy is complex and multifaceted. According to some sources, life expectancy is expected to continue increasing globally, but there are still many challenges to be addressed.

Life expectancy has many practical applications, including in healthcare, insurance, and pension planning. It is used to determine the likelihood of death at a given age, and to calculate the expected length of life.

There are many related topics to life expectancy, including mortality rates, health expectancy, and disability-free life expectancy. These topics are all related to the study of health and longevity, and are used to understand the factors that influence life expectancy.
