NameAgeCountry

NameAgeCountry is a compact data schema used to record basic identifying and demographic information in various systems. It consists of three fields: name, age, and country. The name field stores a person’s full name as text. The age field records a numeric value representing the person’s age, though some implementations may use date of birth instead. The country field captures the respondent’s country of residence, typically stored as an ISO 3166-1 alpha-2 or alpha-3 code or as the full country name.

In practice, systems may validate: name non-empty; age non-negative; country must be a valid code or recognized name. Data types typically include string for name, integer for age, and string for country code or name. Using standardized country codes provides consistency across datasets, while full names can accommodate readable displays. Privacy and governance considerations include obtaining user consent, limiting collection to what is necessary, and applying data minimization and, where appropriate, de-identification or pseudonymization.

Applications for NameAgeCountry include user registrations, surveys, event signups, and basic demographic analytics. Limitations include ambiguity in names, multiple name formats, and the possibility of outdated age data; country information may reflect residence at a point in time or citizenship, and geopolitical changes can affect coding schemes. As an alternative or extension, systems can use separate fields for given names and family names, a date of birth for precise age calculations, and distinct fields for country of residence and country of citizenship to improve accuracy and privacy control.
