Two China national cause-of-death surveys conducted in 1970's and 1990's£º
1. Source of data The data used in preparation came from the nation-wide cancer mortality survey organized by the National Cancer Control Office of the Ministry of Public Health. Using a retrospective method, this three years survey completed an ad hoc investigation of causes of all deaths in years 1973-1975 for a population of approximately 850 million people. We have written a special article to deal with the organization and complement about this survey.

2. Completeness and reliability of the data This survey covered most of the area of China except Taiwan Provo There were altogether 35 counties in Xizang Autonomous Region and Sichuan Provo not surveyed because of their poor communication. (See table)

In order to avoid omission of death cases, we examined and checked data with public security organs and made the supplementary report of infant death cases which were not reported. Hence, the death cases of this survey practically are about 1.5-10.5% more than that mastered by the public security organs, this makes data more completed. This survey was strictly organized and the data were collected by the doctors having specified professional knowledge, checked at every class, therefore the data are reliable. At the same time due to the development of cooperative health service in rural areas, the popularization of medical net, and that most persons had received medical treatment and service before they died, the death causes are basically clear. In order to examine the reliability of data, the leading group of professional guidance at various levels chocked the data by sampling according to the united standard. The result shows that the surveyed data are in accordance with the standard. Additionally, the surveyed data are compared with the dada from the same areas in which there is completed report and registration system of death causes, the result is consistent. So, the quality of this survey is good

3. Classification of death causes Depending on the practical conditions in China and referring. to the lCD, the death causes for this survey is classified. All causes are divided into 20 categories and 56 kinds. The categories of death causes are: 1) Malignant neoplasms; 2) Tuberculosis; 3) Infectious diseases; 4) Parasitic diseases; 5) Injury, poisoning and accidental death; 6) Endocrine, nutritional and metabolic diseases; 7) Blood and blood-forming organ diseases; 8) Mental disorders; 9) Diseases of nervous system; 10) Ischaemic heart diseases; 11) Other heart artery diseases; 12) Cerebrovascular diseases; 13) Diseases of respiratory system; 14) Diseases of digestive system; 15) Diseases of genitourinary system; 16) Diseases of pregnancy, birth trauma and originating in the perinatal period; 17) Congenital anomalies; 18) Neonatal diseases; 19) Other diseases; 20) Diagnosis unclear. The main death causes, such as malignant neoplasms and heart diseases, are classified in detail. In order to be compared with the original domestic data, all death causes are divided into 18 categories according to the report table of the Ministry of Health. Tuberculosis is united with infectious diseases as infectious diseases, and ischaemic heart diseases and other heart diseases are formed into heart diseases.

4. Grading of city and countryside According to their differences, city and countryside are The analysis of death causes of the inhabitants is important in reflecting the people's health state, and also is the scientific bas i s for the study of distribution pattern of the main death causes in China, working out the programme and assessing the effect of health work ¡¢ and realizing the developing tendency of population in our country. Due to the vast territory of China, the physical geographical features of one place are quite different from another. In each area the inhabitants have their own economy, culture, habits and customs. As a result the distribution of death causes varies with local conditions. Therefore mapping out the distribution pattern of the main death causes will be helpful to show these geographical variations in China. This information can be used to help medical departments develop epidemiological research and work out the programmes for prevention and control of main diseases. Under the direct leadership and support of Scientific and Educational Department of the Ministry of Public Health, this set of maps has been finished successfully. This is the first edition of the Atlas of Mortality from Main Death Causes in China, and hence there may be shortcomings or errors in its contents. Please give your critical opinions and suggestions
