SAT personnel stock As of 1980, data given by NESDB Indicate that Thailand had a total of 55,790 scientists and engln~ers (with university ·degrees> and 68,500 technicians (below degree level).

The total employed S&T manpower was estimated to be 286,000 about 1.21 of the total employed. The ratio of S&T man_power by category was :scientists and engineers excluding medical scientists 19.51, technicians 241, and craftsmen 56.51 According to NRC data. the number of researchers working In various sectors In 1981 are: Government sector· University State enterprises Private sector 16-2 2.092 2,893 170 41 233 S&T personnel syryey In 1979, MOSIE conducted S&T personnel survey both In the private sector and the governmeit sector In various educational levels.

In 1984, MOSIE has started the S&T personnel survey project In order to survey the present manpower stock, present and future 
**Analysis**
The text appears to be focused on the availability and distribution of scientific and technological (S&T) manpower in Thailand. It discusses the number of scientists, engineers, technicians, and craftsmen employed in various sectors, including government, universities, state enterprises, and private sector. The text also mentions the difficulty in surveying the private sector and the lack of data on the demand of S&T manpower by industry. Given the focus on S&T manpower, it is likely that the text is related to the development and growth of a country, particularly in the areas of education and employment.
