As of 2023, the countries with the highest life expectancy included Switzerland, Japan, and Spain. As of that time, a new-born child in Switzerland could expect to live an average of **** years. Around the world, females consistently have a higher average life expectancy than males, with females in Europe expected to live an average of *** years longer than males on this continent. Increases in life expectancy The overall average life expectancy in OECD countries increased by **** years from 1970 to 2019. The countries that saw the largest increases included Turkey, India, and South Korea. The life expectancy at birth in Turkey increased an astonishing 24.4 years over this period. The countries with the lowest life expectancy worldwide as of 2022 were Chad, Lesotho, and Nigeria, where a newborn could be expected to live an average of ** years. Life expectancy in the U.S. The life expectancy in the United States was ***** years as of 2023. Shockingly, the life expectancy in the United States has decreased in recent years, while it continues to increase in other similarly developed countries. The COVID-19 pandemic and increasing rates of suicide and drug overdose deaths from the opioid epidemic have been cited as reasons for this decrease.

In 2024, the average life expectancy for those born in more developed countries was 76 years for men and 82 years for women. On the other hand, the respective numbers for men and women born in the least developed countries were 64 and 69 years. Improved health care has lead to higher life expectancy Life expectancy is the measure of how long a person is expected to live. Life expectancy varies worldwide and involves many factors such as diet, gender, and environment. As medical care has improved over the years, life expectancy has increased worldwide. Introduction to health care such as vaccines has significantly improved the lives of millions of people worldwide. The average worldwide life expectancy at birth has steadily increased since 2007, but dropped during the COVID-19 pandemic in 2020 and 2021. Life expectancy worldwide More developed countries tend to have higher life expectancies, for a multitude of reasons. Health care infrastructure and quality of life tend to be higher in more developed countries, as is access to clean water and food. Africa was the continent that had the lowest life expectancy for both men and women in 2023, while Oceania had the highest for men and Europe and Oceania had the highest for women.

The countries with the lowest life expectancy worldwide include the Nigeria, Chad, and Lesotho. As of 2023, people born in Nigeria could be expected to live only up to ** years. This is almost ** years shorter than the global life expectancy. Life expectancy The global life expectancy has gradually increased over the past couple decades, rising from **** years in 2011 to **** years in 2023. However, the years 2020 and 2021 saw a decrease in global life expectancy due to the COVID-19 pandemic. Furthermore, life expectancy can vary greatly depending on the country and region. For example, all the top 20 countries with the lowest life expectancy worldwide are in Africa. The countries with the highest life expectancy include Liechtenstein, Switzerland, and Japan. Causes of death The countries with the lowest life expectancy worldwide are all low-income or developing countries that lack health care access and treatment that more developed countries can provide. The leading causes of death in these countries therefore differ from those of middle-income and upper-income countries. The leading causes of death in low-income countries include diseases such as HIV/AIDS and malaria, as well as preterm birth complications, which do not cause substantial death in higher income countries.

The average for 2022 based on 192 countries was 74.94 years. The highest value was in Macao: 87.98 years and the lowest value was in Nigeria: 53.97 years. The indicator is available from 1960 to 2022. Below is a chart for all countries where data are available.

This dataset explores life expectancy across various countries, analyzing key factors that influence lifespan, such as healthcare, economic conditions, education, and lifestyle choices. By leveraging machine learning techniques, we aim to predict life expectancy trends and identify critical areas for improvement. The insights gained can help policymakers, researchers, and healthcare professionals take informed actions to enhance longevity and overall well-being worldwide.

Monaco had the highest life expectancy among both men and women worldwide as of 2024. That year, life expectancy for men and women was ** and ** years, respectively. The East Asian countries and regions, Hong Kong, Japan, South Korea, and Macao, followed. Many of the countries on the list are struggling with aging populations and a declining workforce as more people enter retirement age compared to people entering employment.

Life Expectancy of the World Population

The dataset from Worldometer provides a ranked list of countries based on life expectancy at birth, which represents the average number of years a newborn is expected to live under current mortality rates. It includes global, regional, and country-specific life expectancy figures, with separate data for males and females. The dataset highlights disparities in longevity across nations, with countries like Hong Kong, Japan, and South Korea having the highest life expectancies. This data serves as a key indicator of public health, quality of life, and healthcare effectiveness, offering valuable insights for policymakers, researchers, and global health organizations.

Data Analysis & Machine Learning Approaches for Life Expectancy Data

Data Analysis Approaches Life expectancy data can be analyzed using descriptive statistics (mean, variance, distribution) and correlation analysis to identify relationships with factors like GDP, healthcare, and education. Time series analysis helps track longevity trends over time, while clustering techniques (e.g., K-Means) group countries with similar patterns. Additionally, geospatial analysis can visualize regional disparities in life expectancy.

Machine Learning Models For prediction, linear and multiple regression models estimate life expectancy based on socioeconomic indicators, while polynomial regression captures non-linear trends. Decision trees and Random Forests classify countries into high- and low-life expectancy groups. Deep learning techniques like neural networks (ANNs) can model complex relationships, while LSTMs are useful for time-series forecasting.

For pattern detection, K-Means clustering groups countries based on life expectancy trends, and DBSCAN identifies anomalies. Principal Component Analysis (PCA) helps in feature selection, improving model efficiency. These methods provide insights into longevity trends, helping policymakers and researchers improve public health strategies.

The average for 2023 based on 47 countries was 75.46 years. The highest value was in Hong Kong: 85.25 years and the lowest value was in Palestine: 65.17 years. The indicator is available from 1960 to 2023. Below is a chart for all countries where data are available.

Context

Life Expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. Cohort LEB is the mean length of life of a birth cohort (all individuals born in a given year) and can be computed only for cohorts born so long ago that all their members have died. Period LEB 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.

Context

While numerous studies have explored the factors influencing life expectancy, most have focused on demographic variables, economic indicators, and mortality rates. However, there has been limited examination of the impact of immunization coverage, health expenditures, and educational attainment on life expectancy. This study seeks to address these gaps by developing a comprehensive dataset with no missing values analyses, utilizing data from many years across 193 different countries. Key immunizations such as Hepatitis B, Polio, and Diphtheria, along with factors like GDP, schooling, and health expenditure, are included in this dataset. This approach aims to identify the most significant predictors of life expectancy, allowing countries to prioritize interventions that could most effectively improve the health and longevity of their populations.

Dataset

The success of this analysis relies heavily on the accuracy and completeness of the data. The dataset used in this project has been sourced from the Global Health Observatory (GHO) data repository of the World Health Organization (WHO), which tracks health metrics and related factors for countries worldwide. The corresponding economic data was obtained from the United Nations. From the broad range of health-related variables available, this study focuses on those that are most representative and critical to understanding life expectancy. The dataset includes data for 193 countries and has been meticulously merged into a single file containing 22 columns and 2,938 rows, representing 20 predictive variables. The variables were categorized into four main groups: Immunization-related factors, Mortality factors, Economic factors, and Social factors. Countries with a lot of missing values were excluded, and some values were generated by Bayesian Ridge.

Question

This dataset aims to answer the following key questions:

1. Do the selected predictive factors significantly impact life expectancy, and which variables are the most influential?

2. Should countries with a lower life expectancy (below 65 years) increase healthcare expenditure to improve their population's lifespan?

3. How do infant and adult mortality rates influence life expectancy across different regions?

4. What is the relationship between life expectancy and lifestyle factors such as alcohol consumption?

5. How does educational attainment, as measured by years of schooling, affect human lifespan?

6. Is there a positive or negative correlation between alcohol consumption and life expectancy?

7. What is the impact of immunization coverage on life expectancy, particularly regarding diseases like Hepatitis B, Polio, and Diphtheria?

This is table showing analysis of countries of the world and it's life expectancy. The term “life expectancy” refers to the number of years a person can expect to live. By definition, life expectancy is based on an estimate of the average age that members of a particular population group will be when they die.
