Technological Framework:

  • Digital Census Applications:
    • Digital Layout Map (DLM): For geotagging homes.
    • Census 2027-Houselist App: For collecting household data through a set of 35 questions.

Pre-Test Phase:

  • The process requires careful handling of household definitions and characteristics, particularly in determining family units based on kitchen sharing.

Public Engagement:

Economic Implications:
