Basic information about the 2021 Census

Concerning the preparation and realization, the census is one of the most demanding and largest statistical surveys, it provides irreplaceable information about the state of society, its demographic, social and economic and cultural structures, dwelling and households.

Preparation of the Population and Housing Census

The main basis for the 2021 Population and Housing Census (2021 Census) was established:

  • first fully electronic census (completely without paper forms)
  • first integrated census (combination of data collected from administrative sources and data collected from the population)
  • preparation for the integrated census was based on the identification of appropriate administrative data sources, negotiations with administrators of administrative data sources took place, cooperation and data provision agreements were concluded, cooperation and communication with source administrators followed, the National Action Plan of the 2021 Census was developed as a platform for inter-ministry cooperation
  • data from administrative sources were analysed, usefulness of data for the 2021 Census and data quality were evaluated, data were processed; a territorial preparation for the 2021 Census was proposed and implemented
  • the methods of data collection for the population and housing census were specified, testing of them was realized, the census stages and their deadlines were set, the decisive moment of the census was set, professional studies were developed
  • the surveyed variables and their sources were defined (administrative data sources, municipality, resident)
  • the Act on the 2021 Population and Housing Census, related measures, methodological guidelines, methodological manuals were issued
  • census forms for the housing census (a database and questionnaire form) and census forms for the population census (type A form, type B form) were developed and tested with the relevant methodological explanations
  • the website www.scitanie.sk was set up
  • a nationwide communication and promotional campaign of the 2021 Census were conducted

Preparation

Creation and testing

  • electronic system for the hosing census (environment for the collection of data on dwellings from municipalities)
  • electronic system for the population census (census web application, census mobile application, stationary assistant application, mobile assistant application, e-environment for contact persons)
  • internal monitoring of the housing census for municipalities and the SR
  • internal monitoring of the population census for municipalities and the SR
  • training portals (e-learning) for persons in the municipality, who were authorised to conduct the housing census (authorized persons and managers of authorized persons), for persons in the municipality, who acted as staff for the population census (contact persons, stationary and mobile assistants) and for call centre staff

Territorial preparation

  • generally, territorial preparation is a tool for territorial administration to prepare and conduct each statistical survey, it defines the space of survey realization and identifies the objects to be covered
  • territorial preparation is an essential element even for the largest statistical survey, which is the population and housing census.

Territorial preparation for the 2021 Census means the spatial and database identification of all objects (dwellings), in which the population of Slovakia could live at the time of the census and thus in which they could be counted.

Vision of the territorial preparation: each resident will be counted, will be counted only once and will be counted in a geolocation place.

Data sources used in the processing of the Territorial Preparation for the 2021 Census:

  • the Address Register (AR) - Ministry of the Interior of the SR
  • the Information System of Cadastre of Real Estate (ISCRE) - Geodesy, Cartography and Cadastre Authority of the SR
  • Basic database for geographic information system (BD GIS) - Institute of Geodesy and Cartography
  • 2011 Population and Housing Census
  • the Register of Natural Persons (RNP) - Ministry of the Interior of the SR
  • the Basic Settlement Units (BSU) - Ministry of the Environment of the SR

The Territorial Preparation Information System (TP IS) = an integrated solution for the collection, updating, administration and provision of geolocation data is a result of the Territorial Preparation for the 2021 Census. The data part of the Territorial Preparation thus consists of the maximum set of all possible occupied or unoccupied geolocation objects, including huts, garden huts, shacks, houseboats, etc. collected from administrative data sources and in the field.

Data of the TP IS are a basis for:

  • Electronic Housing Census
  • Electronic Population Census
  • Census monitoring during e-collection of data on population and housing

Innovations of the Territorial preparation in comparison with the 2011 Population and Housing Census

  • new concept of the 2021 Census - INTEGRATED CENSUS - was reflected in the main basis for the solution of the TP IS, several administrative data sources (not only KN) were used and the TP IS was integrated directly with the Register of Addresses
  • in terms of territorial detail, data are collected at the level of the geolocation address point, while in the past, census districts, which included a larger number of habitable objects, were set up for the purposes of the census territorial preparation
  • the system is suggested as a sustainable system for future censuses and post-censuses
