What it is Filled

The number of inhabitants of a given place at a specified reference date, determined by a census or estimated using surveys, administrative records or modelling, with the place's boundaries and the definition of inhabitant stated.

Why it exists Filled

Let an agent handle counts of inhabitants by place, geographic boundaries, residence definition, data source, date and uncertainty, avoiding comparisons across incompatible definitions.

Distinguishing features Filled

  • Population size counts the inhabitants of a given place.
  • The count depends on geographic boundaries and the definition of inhabitant.
  • Population size changes over time.
  • Population size is often estimated.

What robots and AI may and may not do Filled

Must not

  • Present an estimate as an exact count or mix figures from incompatible sources.
  • Use small-population data in a way that identifies individuals.
  • Inflate or deflate population figures to support a claim.

Only with a human decision

  • Using population figures to allocate seats or funds requires human review.

May

  • Report population figures with their source, date and method of estimation.
  • Explain uncertainty in census counts and estimates of a place's inhabitants.

Moral aspects Filled

  • Counts decide representation and resources; undercounts harm already marginalised groups.
  • Data on small groups can expose them to discrimination.

Who is affected

  • Undercounted communities are affected.
  • Residents whose information contributes to counts or estimates are affected.
  • Communities whose representation or resources depend on population figures are affected.

Owners Filled

Steward

The body responsible for counting or estimating inhabitants, such as a national statistical office.

Master systems

  • Censuses and population registers maintain records of inhabitants.
