[Territorial mobility based on census data: the estimation of migratory flows]

Area of Science:

• Demography
• Population Studies
• Migration Research

Context:

• Population censuses collect retrospective data on place of residence.
• Migration estimates derived from censuses often omit individuals who died or emigrated.
• Accurate migration data is crucial for demographic analysis and policy.

Purpose:

• To present a method for estimating deaths among migrants within a specific period.
• To apply this estimation method to Italian census data from 1971 and 1981.
• To address limitations in retrospective census data for migration studies.

Summary:

• Retrospective census questions allow calculation of migration numbers but exclude deceased or emigrated individuals.
• While emigration cannot be estimated, a method exists to estimate migrant deaths.
• This paper applies the migrant death estimation method to Italian census data.

Impact:

• Improves the accuracy of demographic estimations in population studies.
• Provides a methodology applicable to other national census datasets.
• Enhances understanding of migration dynamics by accounting for mortality.
