Persons usually resident in the place of enumeration but absent, or expected to be absent, at the time of the census for less than one year shall be considered as temporarily absent persons and thus included in the total unsually population. In contrast, persons living or expected to live outside the place of enumeration for one year or more shall not be considered temporarily absent and shall therefore be excluded from the total population. This is regardless of the length of visits that they may pay to their families from time to time.
Persons who are enumerated but do not meet the criteria for usual residence in the place of enumeration, i.e. do not live or do not expect to live in the place of enumeration for a continuous period of at least 12 months, are considered temporarily present and are therefore not counted in the total usually resident population.

Comparable.
16.2. Comparability - over time
2011 Census data are not comparable with previous censuses in Croatia due to different definition of total population (usual residence in 2011).
Also, different definition of economic activity in 2011 is used (current activity in reference week) in comparison with previous censuses when prevailing activity during previous year was used.
17.1. Coherence - cross domain
Figures provided by the National Statistical Institutes in the framework of the 2011 Population and Housing Census may differ from those transmitted in other statistical domains due to the cross domain differences in definitions and methodologies used. For additional information please see metadata specific to each domain.
17.2. Coherence - internal
Internal coherence is assured by regulations defining breakdowns and definitions of topics (Regulation (EC) No 1201/2009, Regulation (EU) No 519/2010, Regulation (EU) No 1151/2010)
The total census budget was approx. 21 million euros. The Census Budget was set by the Census Law and was covered in the budged for the years 2010, 2011 and 2012. The final census costs is considerably less – approximately 15.5 million euros.
The 2011 Census did not place any particular burden to respondents.

20.3. Data collection
As a part of the preparatory work for the 2011 Census, the Census Test was carried out in 2009 in order to test methodological, organisational and IT solutions.
2011 Census was carried out by traditional method, i.e. face-to-face interviews using paper forms (Personal Questionnaire and Household and Dwelling Questionnaire).
There were 3 enumeration units: population, households and dwellings.
The Census was carried out in the period 1-28 April 2011 in accordance with the situation on 31 March 2011 at midnight.
Post enumeration survey was carried out immediately after the Census, in the period 2-10 May 2011, on the sample of approx. 1.4% of households in the Republic of Croatia.
Before enumeration started, general public had been informed through communication chanells. Also, CBS established Call Center and web page specifically designed for the Census. The web page included answers to frequently asked questions, census questionnaires as well as a list of enumeration centers.
2011 Census was prepared, organised and executed by the Croatian Bureau of Statistics. The State Geodetic Administration was responsible for preparing the list of spatial units and descriptive cartographic materials.
For the purpose of preparation, organisation and execution of the 2011 Census in the field, the following bodies were set up hierarchicaly: county census committees, census committees in town/municipalities. Within the area of their competence, mentioned bodies set up census centers and nominated and/or apponited participants of 2011 Census (enumerators and controllers).
Out in the field there were 13943 enumerators, 1950 controllers (enumerators' supervisors), 193 instructors, as well as 45 county coordinators. Additional participants include members of county census committees, census committees in towns/municipalities and members of census centers.
After the enumeration on the field had finished, entire census material were transported and stored in one place, and afterwards data processing started.
20.4. Data validation
Data validation started at the beginning of enumeration in sense that controllers (enumerators’ supervisors) daily checked questionnaires filled in by enumerator and made corrections in case of inconsistency or mistake. Also, random checks of census questionnaires were done in census centres during entire period of enumeration.
Data validation continued through data processing system starting with manual checks (checking whether all addresses are comprised and checking identification numbers).
After questionnaire scanning and coding, various checks followed. Many corrections were done automatically using automated editing. Also, there were around 20 types of on-line editing, performed by operators who used manuals (explaining how to correct mistakes) prepared by the CBS staff. All inconsistences were corrected on micro level.
Final data validation refers to analysing numerous tables through cross-variables checks. Those tables were analysed by experienced CBS staff and, if necessary, inconsistences were corrected on micro-level.
At the final stage, 2011 Census data were validated by: comparison with previous census data; comparison with LFS and other surveys; comparison with administrative sources.
20.5. Data compilation
IFP (Intelligent Forms Processing) was used for document capture. We have used four Kodak scanners and captured all of the documents in both TIFF and PDf format. All of the captured data was imported into a SQL 2008R2 database, forming two main tables – data from personal questionnaires and data from Household and Dwelling Questionnaire. Both tables are linked by identifiers (town/municipality code, enumeration area code, dwelling code, household code, person ordinal within the household). The forms were then processed using in-house developed applications and commercial software.
Most of the software was developed in-house, using Microsoft Visual Basic for .NET and SQL Server 2008R2, with the exception of software for data capture, coding and analysis.
Parallel to the Census database, test database was used for testing both on-line editing and batch jobs.
Separate database was used for data coding. ACTR software (Automated Coding by Text Recognition) developed by Statistics Canada was used for automated coding, accompanied with our own on-line application for computer aided coding, and based on the ACTR results. In that manner the following variables were coded: Settlement Street, town/municipality, foreign country, citizenship, ethnicity, mother tongue, religion, title of the highest completed school, vocation/field of education, occupation, and industry.
Each operator could, while editing and correcting data, display the appropriate form and depending forms in PDF format. All of the operators' actions were recorded. Control tables were prepared in MS Excel. Methodologists were able to browse the data and prepare their own views using SAS Enterprise Guide Software.
The deleted records were just marked as deleted, but physically remained in the database. Imputations rules were developed by demographic experts, and then tested using the test database. All of the changes were analysed before applying them to the actual data.
The final results were published on our website in HTML and Excel format. Currently, we have prepared them for PC-Axis and they will be presented in .px form as well. The Census Hub has been established with the help of Eurostat experts, and we are currently in the process of preparing and publishing data using the Census Hub. It is also possible to search names and surnames on our website based on data collected in the 2011 Population Census, where one can find out how many persons have certain name, surname or full name combinations.
20.6. Adjustment
The Croatian 2011 Census was carried out by means of the traditional method using paper-assisted personal interviews (PAPIs). The census day was 31 March 2011 and the enumeration period 1 – 28 April 2011.The Post-enumeration survey was carried out in the period 2-10 May 2011 on the sample of approximately 1.4% of households in the Republic of Croatia.
There were 3 enumeration units: persons, households and dwellings.
The number of enumerators was 13943 and the number of controllers (supervisers of enumerators) was 1950.
The basic questionnaires were the 'Personal Questionnaire' and the 'Household and Dwelling Questionnaire'.
The legal framework for the conduction of the 2011 Population Census in Croatia was the Act on the Census of Population, Households and Dwellings in the Republic of Croatia in 2011. The Act was adopted by the Croatian Parliament in July 2010, and is harmonized with the Regulation (EC) No 763/2008.
The State Geodetic Administration was in charge for the updating and preparing the lists of spatial units and descriptive cartographic materials.
The optical character recognition (OCR) was used in the data processing.
The preliminary 2011 Census results were published on 29 June 2011 (the total number of population, households and dwellings). The first part of the final results were published in December 2012 and the rest of them in 2013 and 2014.
The total census budget was approximately 21 million euros. The final census costs is considerably less – approximately 15.5 million euros.
The EU programme for the 2011 population and housing censuses include data on persons, private households, family nuclei, conventional dwellings and living quarters
Persons enumerated in the 2011 census are those who were usually resident in the territory of the reporting country at the census reference date. Usual residence means the place where a person normally spends the daily period of rest, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage
Data are available at different levels of geographical detail: national, NUTS2, NUTS3 and local administrative units (LAU2)
