The Ministry of Manpower (MOM) is conducting a labour force survey on 33,000 households over two months.
MOM said in a statement that the Comprehensive Labour Force Survey - which started yesterday - will be carried out on a random sample of households, who will be notified by post if they have been selected.
It is conducted by MOM's manpower research and statistics department, and will take place until July 31.
Information collected in the survey will be used to compile manpower statistics to help in the formulation of policies and programmes, the statement said.
All members of a household selected for the survey will be asked about personal and labour-related information such as education, labour force status and job details.
Survey participants will have to provide their contact information for further verification, if needed.
Households are encouraged to participate in the survey online through the Manpower Survey Online System.
If not, MOM interviewers will call or visit them.
Interviewers will show an identification card issued by MOM. Households that would like to verify the identity of the interviewer can call the survey hotline on 6317-1009.
MOM said the survey is conducted in accordance with the Statistics Act, which safeguards the confidentiality of the information provided.
Under the Act, it is also compulsory for all selected households to provide the ministry with the necessary information for the survey.
