The concept of a ‘house listing’ operation in the Census refers to:

Preliminary survey to identify households
Enumeration of homeless population
Assessment of housing quality
None of the above

The correct answer is: Preliminary survey to identify households.

A house listing operation is a preliminary survey that is conducted before the main census to identify all the households in a given area. This information is then used to create a master address list, which is used to enumerate the population during the main census.

The other options are incorrect because:

  • Enumeration of homeless population is not a part of house listing operation. Homeless people are enumerated during the main census, not during the house listing operation.
  • Assessment of housing quality is not a part of house listing operation. Housing quality is assessed during the main census, not during the house listing operation.

I hope this helps! Let me know if you have any other questions.
