• UN recommended that a post-enumeration Survey
  (PES) be undertaken
• within three months after the enumeration to
  determine the degree
• of under-or over count in a population and
  housing censuses

Post Enumeration Survey
The Objectives of the PES were

• To assess the degree of courage during the
  census enumeration
• To examine the implication of coverage
  deficiencies, if any on the
• usefulness of the census data
• To obtain information for the design of future
  censuses and survey
• To examine the characteristics of persons who
  may have been missed
• during the census enumeration
