The Census & Statistics Department will conduct a pilot survey from June 30 to August 2 to prepare for the 2016 Population By-census.
The By-census will be launched in mid-2016.
Three-thousand quarters in Eastern, Sham Shui Po, Yau Tsim Mong and Yuen Long have been selected to test the census questionnaire design and operational arrangements.
The department will send letters to sampled households today informing them that they have been selected.
Respondents can choose to complete the questionnaire online or by using the e-Questionnaire mobile app.
From July 16 to August 2, the department will arrange for census officers to visit households that have not yet completed their electronic questionnaires. The officers will use mobile tablets to collect the data.
All information collected will not be released. All questionnaires will be destroyed within a year.
