Definition
A census in Peru is an official, systematic enumeration of the country’s population and housing units, conducted by the Instituto Nacional de Estadística e Informática (INEI) under the legal authority of the Peruvian government. The primary purpose is to collect demographic, social, economic, and geographic data for public policy, planning, and research.
Overview
Since the late 19th century, Peru has carried out a series of national censuses at irregular intervals, later standardizing to a roughly decennial schedule. The most recent comprehensive population and housing census was completed in 2017, with an additional agricultural census conducted in 2016. The INEI is responsible for designing the questionnaire, training enumerators, supervising field operations, processing data, and publishing the results. Census data are widely used by government ministries, academic institutions, international organizations, and the private sector.
Etymology / Origin
The term “census” derives from the Latin censere, meaning “to assess” or “to estimate.” In the context of governmental statistics, it entered English via Old French cens and has been used in Spanish as censo since the medieval period. The phrase “Census in Peru” therefore combines the generic concept of a population count with the national jurisdiction in which it is administered.
Characteristics
- Legal Framework: The census is mandated by the Law of the National Statistics System (Ley del Sistema Nacional de Estadística) and specific legislative decrees that define its periodicity, scope, and funding.
- Frequency: While early censuses occurred at irregular intervals, modern practice aims for a ten‑year cycle for the population and housing census (e.g., 2007, 2017). Specialized censuses, such as the agricultural census, follow separate schedules.
- Agency: The Instituto Nacional de Estadística e Informática (INEI) coordinates all stages, from methodological design to data dissemination.
- Scope and Content: The questionnaire typically covers age, sex, marital status, ethnicity, education, employment, migration, housing conditions, and access to basic services. The agricultural census records land use, crop production, livestock, and farm management practices.
- Methodology: Data collection combines face‑to‑face interviews, electronic devices (e.g., tablets with GIS integration), and self‑response options for urban areas with internet access. Quality control measures include post‑enumeration surveys and consistency checks.
- Coverage: The census aims for universal coverage of Peru’s 25 regions, including remote Andean communities, Amazonian territories, and coastal urban centers. Special protocols address language diversity, with instruments available in Spanish, Quechua, Aymara, and other indigenous languages.
- Publication and Use: Results are released in detailed tables, thematic reports, and interactive databases. They inform electoral districting, fiscal allocation, health and education planning, infrastructure development, and monitoring of Sustainable Development Goals (SDGs).
