Statistics compiled from manpower surveys have played a very essential role in modern nations as they pursue socio-economic development. To this end, countries all over the world have spared no effort to conduct this type of survey carefully and seriously in order to regularly obtain reliable manpower statistics that will satisfy their requirements in planning manpower allocation and implementing national construction programs. National natural resources are limited in Taiwan .Thus it is especially important to deal with issues such as how to effectively use manpower and how to balance manpower demand and supply. The supply of manpower among the civilian population of ages 15 and above who are capable of and willing to work is regularly surveyed and analyzed for the following purposes:
Preparation of manpower statistics in this country began in April 1962 when the Taiwan Provincial Department of Social Affairs set up the Labor Force Survey, Statistics, Research, and Development Group to establish a labor force survey system. The group was later reorganized into the Labor Force Survey and Research Group. which formally launched a quarterly labor force survey in October 1962. The group was again reorganized into the Labor Force Survey and Research Institute. charged with full responsibility for conducting labor force surveys. In view of the growing importance of manpower planning, the DGBAS was assigned to take over the Taiwan area labor force survey in 1977. A provisional organization entitled the "Labor Force Survey Statistics Evaluation Committee" was established in August of that year, with domestic experts and scholars invited to provide advice for practical operation and help formulate various reform measures. Two trial surveys were conducted in November and December 1977. The first formal survey was started in January 1978. Subsequently, manpower data from the surveys was used more and more extensively, receiving much attention from all sorts of users. To strengthen functions of the organization, the committee was officially incorporated into the Fourth Bureau of DGBAS in July 1983.
The manpower statistics prepared by the DGBAS take households as a base and utilize sampling surveys to collect basic data such as quality, quantity, labor force structure, employment, unemployment, reasons of unemployment, and composition of those not in labor force among the civilian population ages 15 and above. To meet the requirements of other government agencies in their manpower management and socioeconomic policy enforcement and decision-making, fourteen supplementary surveys have been conducted, using the same sample, to collect more detailed data. These supplementary surveys include: (1) Manpower Utilization Survey, (2) Work Experiences Survey, (3) Housing Status Survey, (4) Women's Marriage, Fertility And Employment Survey , (5) Prevalent Diseases, Medical Aids And Employment Survey, (6) Internal Migration Survey, (7) Vocational Training Survey, (8) Youth Status Survey, (9) Elderly Status Survey（Middle-aged and Elderly Status Survey）, (10) Time Utilization Survey, (11) People's Leisure Life Survey, (12) Job Expectations Survey, (13) People's Cultural Demands Survey and (14) Citizen's Lifestyle and Ethics Survey. The results of which are all published in separate, special publications.
