Data collection – Centralised in one data collection division (registers and surveys) – Efficiency and professionality – Using the same infrastructure for social and economic statistics as much as possible – Collection strategy (preferred order): – register data – sample surveys – Only existing sources have been used for the Census 2011 – No Census 2011 questionnaires! 3
Data sources For the Census 2011: – Registers – – – – Population Register (automated population registration system) Jobs file (all employees) Self‐employed file (all self‐employed) Fiscal administration Social security administration Pensions and life insurance benefits Housing Register – Survey – Labour Force Survey 4

Characteristics of the Dutch census – – – – – Relatively cheap Short production time More socially acceptable than the Census 1971 All tables are numerically consistent Some missing information in the survey part Dependent on registers (availablility, timeliness) Comparisons over time possible International comparisons possible Census data continuously available 10
Conditions facilitating use of administrative sources – Legal base (Statistics Act) – Public approval (‘Big Brother is watching you’) – Cooperation among authorities (mainly government organisations) – Comprehensive and reliable register system (administrative versus statistical quality) – Unified identification system (preferably unique ID‐ numbers) 11

Censuses in the UNECE region 13
Current and future work Preparing the Census 2021: – New European implementing regulations (based on UNECE recommendations) – Preparatory projects at Statistics Netherlands: ‐ Methodology (estimating occupation tables) ‐ Software ‐ Level of education attained (imputing the Educational Attainment File) ‐ Housing variables ‐ Population grid squares (legal base, protection of census data) 14
Yearly census results (1) – Statistics Netherlands publishes over 100 census tables on a yearly basis about persons and households (not about housing) based on the SSD with extra variables / categories but lower dimensional tables – Extra regional categories: municipalities around biggest cities and postal code – Age partner (in classes) – Extra socio‐economic categories: employee private sector, civil servant and unfit for work – Personal and household income (both in classes) – Highest level of education attended 15
Yearly census results (2) – Current situation in Europe leads to outdated census publications (Census 2011 were published at the end of 2014) – Users are looking for other sources than the census – Census budgets are no longer justified and are shrinking – Additional publication of yearly tables will make the census information much more useful 16
Yearly census results (3) – The level of detail in yearly census tables should be more limited than in the current tables published every ten years – All countries could participate, either by using registers or by yearly updates – We need time to come to a change – Strategy: first the European Census 2021, then yearly updates (from 2025 with reference years one year earlier) 17
Thank you very much for your attention! Holland in the winter 18
