Hallintadataa

Hallintadataa, or administrative data, refers to data produced or collected by public sector authorities in the course of delivering public services and managing governance. This type of data is generated during routine operations, such as registry entries, case management records, service transactions, and digital interactions with public services. Because hallintadataa often concerns individuals, its collection and use are governed by privacy, data protection, and governance requirements. It is increasingly used for official statistics, research, policy evaluation, and service development.

Sources and content are diverse. Common examples include population registers, tax and social security records, health care and social services data, education records, housing and property registries, and administrative logs from online services. Data may be structured in databases or stored as unstructured documents. When combined across agencies, hallintadataa enables a more complete view of social and economic phenomena, but also poses interoperability and data quality challenges.

Uses and benefits include producing register-based statistics, evaluating public programs, informing policy decisions, and supporting digitalisation and service redesign. Administrative data can reduce the need for separate surveys, increase timeliness, and improve accuracy for large populations. However, realizing these benefits requires robust data governance, clear data ownership, access controls, and processes for data linkage, quality assurance, and secure data sharing.

Governance and privacy considerations are central. Access to hallintadataa is typically regulated by laws and guidelines on data protection, data minimisation, and purpose limitation. Data custodians and approved researchers may access de-identified or legally authorized data, with safeguards such as data protection impact assessments and audit mechanisms to protect individual privacy and prevent misuse.
