Background: This study analyzed the causes of death in the Korean population in 2020. Methods: Cause-of-death data for 2020 from Statistics Korea were examined based on the Korean Standard Classification of Diseases and Causes of Death, 7th revision and the International Statistical Classification of Diseases and Related Health Problems, 10th revision. Results: In total, 304,948 deaths occurred, reflecting an increase of 9,838 (3.3%) from 2019. The crude death rate (the number of deaths per 100,000 people) was 593.9, corresponding to an increase of 19.0 (3.3%) from 2019. The 10 leading causes of death, in descending order, were malignant neoplasms, heart diseases, pneumonia, cerebrovascular diseases, intentional self-harm, diabetes mellitus, Alzheimer disease, liver diseases, hypertensive diseases, and sepsis. Cancer accounted for 27.0% of deaths. Within the category of malignant neoplasms, the top 5 leading organs of involvement were the lung, liver, colon, stomach, and pancreas. Sepsis was included in the 10 leading causes of death for the first time. Mortality due to pneumonia decreased to 43.3 (per 100,000 people) from 45.1 in 2019. The number of deaths due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was 950, of which 54.5% were in people aged 80 or older. Conclusion These changes reflect the continuing increase in deaths due to diseases of old age, including sepsis. The decrease in deaths due to pneumonia may have been due to protective measures against SARS-CoV-2. With the concomitant decrease in fertility, 2020 became the first year in which Korea’s natural total population decreased.

Background: This study aimed to present and analyze the causes of death in the Korean population in 2019. Methods: Based on the Korean Standard Classification of Diseases and Causes of Death and the International Statistical Classification of Diseases and Related Health Problems, 10th revision, cause-of-death data for 2019 from Statistics Korea were examined. Results: There were 295,110 total deaths, a decrease of 3,710 (-1.27%) from 2018. The crude death rate (the number of deaths per 100,000 people) was 574.8, a decrease of 7.6 (-1.3%) from 2018. The top ten causes of death, in descending order, were malignant neoplasms, heart disease, pneumonia, cerebrovascular disease, intentional self-harm, diabetes mellitus, Alzheimer disease, liver disease, chronic lower respiratory disease, and hypertension. Within the malignant neoplasm category, the top five organs affected were the lung, liver, colon, stomach, and pancreas (in the same order as in 2018). Alzheimer disease moved up from ninth to seventh on the list of leading causes of death in 2018. Among women, it ranked as the fifth leading cause of death, while pneumonia became the third leading cause of death. Conclusion These changes reflect the increasing number of women > 65 years who are vulnerable to cognitive impairment and infectious diseases. The Korean government must urgently take preventive and therapeutic measures against dementia, especially Alzheimer disease.

This study aimed to analyze changing trends in child injury deaths from 2006 to 2016 and to provide basic data for initiatives to help prevent child injury deaths through improvements in social systems and education. Specific causes of death were analyzed using micro-data of the death statistics of Korea from 2006 to 2016, which were made available by Statistics Korea. Types and place of death were classified according to the KCD-7 (Korean Standard Classification of Diseases and Causes of Death). The data were compared to those of other Organization for Economic Cooperation and Development countries. Changing trends were presented. The number of child deaths by injury was 270 in 2016. The death rate was 8.1 per 100,000 population in 2006, while it was 3.9 in 2016. The death rate of boys was 1.7 times greater than that of girls. Unintentional injury deaths comprised 72.6% of all child injury deaths in 2016, while intentional injury deaths comprised 27.4%. The first leading cause of unintentional injury deaths in infants (less than 1-year-old) was suffocation, while that of children aged 1 to 14 years was transport accidents. The second leading cause of death in infants was transport accidents, that of children aged 1 to 4 was falling, and that of children aged 5 to 14 was drowning. Pedestrian accidents comprised 43.7% of the transport accidents from 2014 to 2016. To prevent child injury deaths by both unintentional and intentional causes, nation-wide policy measures and more specific interventions according to cause are required.

This study aimed to analyze infant, maternal, perinatal, and fetal mortality statistics in the Republic of Korea (Korea), 2014. It was based on the open-access data available from the Statistics Korea website (http://kostat.go.kr/portal/eng/index.action). Recent trends in these vital statistics were also examined. The results of this study constitute a descriptive presentation and analysis of the national data. The number of infant deaths was 1,305 out of 435,435 live births in 2014, and the infant mortality rate was 3.0. The number of maternal deaths was 48. The maternal mortality ratio per 100,000 live births was 11.0. The maternal mortality ratio per 100,000 women of child-bearing age (15 to 49 years old) was 0.37. The number of perinatal deaths was 1,365, and the perinatal mortality rate was 3.1. The number of fetal deaths was 5,317. The fetal mortality rate was 12.1. The trends in those vital statistics in recent years were consistent except for a few findings, including a decrease in the maternal mortality ratio of pregnant women 40 years old and older and a change in the proportions of the causes of infant death, with a decrease in mortality due to neonatal respiratory distress and an increase in mortality due to bacterial sepsis. Although these vital statistics were generally consistent, some aspects varied by year. Pregnant women less than 20 years old should be monitored more intensively for their babies' health. Our findings can serve as basic data supporting the establishment of health policies by the Korean government.

This study aimed to analyze changes in the causes of death in the Korean population in 2016 and to provide some insights regarding how to cope with related issues of public health and welfare. The causes of death made available by Statistics Korea were classified according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision as well as the KCD-7 (Korean Standard Classification of Diseases and Causes of Death), which has been modified to fit circumstances in Korea. The total number of deaths was 280,827, which was an increase of 4,932 (1.8%) from 2015. The crude death rate was 549.4 per 100,000 population, which was an increase of 7.9 (1.5%) from 2015. The 10 leading causes of death, in order, were malignant neoplasms, heart diseases, cerebrovascular diseases, pneumonia, intentional self-harm, diabetes mellitus, chronic lower respiratory diseases, liver diseases, hypertensive diseases, and transport accidents. The rank of hypertensive diseases rose from 10th in 2015 to 9th in 2016, while that of transfer accidents dropped from 9th in 2015 to 10th in 2016. The proportion of the number of deaths caused by cancer was 27.8%. The death rate due to cancer was 153.0 per 100,000 population, which was an increase of 1.4% from 2015; 16.5 deaths per 100,000 population were due to colon cancer, and 16.2 were due to stomach cancer. The above trends in causes of death reflect aspects of the population structure, disease patterns, lifestyle, and medical care in present-day Korean society.
