The first phase of the census involves:

Data analysis
House listing and house numbering
Publicity and awareness campaigns
Training of enumerators

The correct answer is: b) House listing and house numbering.

House listing and house numbering is the first phase of the census. It involves identifying and numbering all the houses in a given area. This is done by enumerators who visit each house and collect basic information about the household, such as the number of people living there and their ages. This information is then used to create a master list of all the households in the area.

The other options are incorrect because they are not the first phase of the census.

  • Data analysis is the process of examining and interpreting data collected during the census. This is done to identify trends and patterns in the data.
  • Publicity and awareness campaigns are used to inform the public about the census and encourage them to participate.
  • Training of enumerators is the process of teaching enumerators how to conduct the census.
