It was by far the most thorough and accurate census taken since and confirmed that China was a nation of more than 1 billion people, or about one-fifth of the world's population. The census provided demographers with a set of data on China's age-sex structure, fertility and mortality rates, and population density and distribution. Information was also gathered on minority ethnic groups, urban population, and marital status.
Information was also gathered on minority ethnic groups, urban population, and marital status. The nation began preparing for the census in late Chinese census workers were sent to the United States and Japan to study modern census-taking techniques and automation.
Computers were installed in every provincial-level unit except Tibet and were connected to a central processing system in the Beijing headquarters of the State Statistical Bureau. Pretests and small scale trial runs were conducted and checked for accuracy between and in twenty-four provincial-level units.
Census stations were opened in rural production brigades and urban neighborhoods. Beginning on 1 Julyeach household sent a representative to a census station to be enumerated.
The census required about a month to complete and employed approximately 5 million census takers. The census collected data in nineteen demographic categories relating to individuals and households.
The thirteen areas concerning individuals were name, relationship to head of household, sex, age, nationality, registration status, educational level, profession, occupation, status of nonworking persons, marital status, number of children born and still living, and number of births in The six items pertaining to households were type domestic or collectiveserial number, number of persons, number of births innumber of deaths inand number of registered persons absent for more than one year.
Information was gathered in a number of important areas for which previous data were either extremely inaccurate or simply nonexistent, including fertility, marital status, urban population, minority ethnic groups, sex composition, age distribution, and employment and unemployment.
A fundamental anomaly in the statistics was noted by some Western analysts. They pointed out that although the birth and death rates recorded by the census and those recorded through the household registration system were different, the two systems arrived at similar population totals.
The discrepancies in the vital rates were the result of the underreporting of both births and deaths to the authorities under the registration system; families would not report some births because of the one-child policy and would not report some deaths so as to hold on to the rations of the deceased.
Nevertheless, the census was a watershed for both Chinese and world demographics. After an eighteen-year gap, population specialists were given a wealth of reliable, up-to-date figures on which to reconstruct past demographic patterns, measure current population conditions, and predict future population trends.
For example, Chinese and foreign demographers used the census age-sex structure as the base population for forecasting and making assumptions about future fertility trends.
The data on age-specific fertility and mortality rates provided the necessary base-line information for making population projections.
The census data also were useful for estimating future manpower potential, consumer needsand utilityenergy, and health-service requirements.
The sudden abundance of demographic data helped population specialists immeasurably in their efforts to estimate world population.
But the liabilities of a large, rapidly growing population soon became apparent.
These efforts, however, had little impact on fertility.The demographics of China are identified by a large population with a relatively small youth division, which was partially a result of China's one-child policy, which was modified to a two-child policy in China's population reached the billion mark in Jul 23, · By Andrew Mason.

With a population estimated at billion people as of , China clearly ranks as the world's most populous country. With the world's population approximately billion, China represents 20 percent of the people on Earth. However, policies the government has implemented over the years may well result in China losing that top ranking in the near future.
