The 2005 Census of Population and Housing was the third comprehensive data collection of population and housing characteristics taken by the Republic since Compact Implementation in October 1994. The 2005 census was fully funded by the government of the Republic of Palau, following the 1995 and 2000 Censuses. OPS played the key role in collection and processing the 2005 Census information and was also the lead agency analyzing the data.
The 2005 Republic of Palau Census of Population and Housing will be used to give a snapshot of Republic of Palau's population and housing at the mid-point of the decade. This Census is also important because it measures the population at the beginning of the implementation of the Compact of Free Association. The information collected in the census is needed to plan for the needs of the population. The government uses the census figures to allocate funds for public services in a wide variety of areas, such as education, housing, and job training. The figures also are used by private businesses, academic institutions, local organizations, and the public in general to understand who we are and what our situation is, in order to prepare better for our future needs.
The fundamental purpose of a census is to provide information on the size, distribution and characteristics of a country's population. The census data are used for policymaking, planning and administration, as well as in management and evaluation of programmes in education, labour force, family planning, housing, health, transportation and rural development. A basic administrative use is in the demarcation of constituencies and allocation of representation to governing bodies. The census is also an invaluable resource for research, providing data for scientific analysis of the composition and distribution of the population and for statistical models to forecast its future growth. The census provides business and industry with the basic data they need to appraise the demand for housing, schools, furnishings, food, clothing, recreational facilities, medical supplies and other goods and services.

Dates of Data Collection
Data Collection Mode
The 2005 Palau Census of Population and Housing comprises three parts:
1. Housing - one form for each household
2. Population - one for for each member of the household
3. People who have left home - one form for each household.
Full scale processing and editing activiities comprised eight separate sessions either with or separately but with remote guidance of the U.S. Census Bureau experts to finalize all datasets for publishing stage.
Processing operation was handled with care to produce a set of data that describes the population as clearly and accurately as possible. To meet this objective, questionnaires were reviewed and edited during field data collection operations by crew leaders for consistency, completeness, and acceptability. Questionnaires were also reviewed by census clerks in the census office for omissions, certain inconsistencies, and population coverage. For example, write-in entries such as "Don't know" or "NA" were considered unacceptable in certain quantities and/or in conjunction with other data omissions.
As a result of this review operation, a telephone or personal visit follow-up was made to obtain missing information. Potential coverage errors were included in the follow-up, as well as questionnaires with omissions or inconsistencies beyond the completeness and quality tolerances specified in the review procedures.
Subsequent to field operations, remaining incomplete or inconsistent information on the questionnaires was assigned using imputation procedures during the final automated edit of the collected data. Allocations, or computer assignments of acceptable data in place of unacceptable entries or blanks, were needed most often when an entry for a given item was lacking or when the information reported for a person or housing unit on that item was inconsistent with other information for that same person or housing unit. As in previous censuses, the general procedure for changing unacceptable entries was to assign an entry for a person or housing unit that was consistent with entries for persons or housing units with similar characteristics. The assignment of acceptable data in lace of blanks or unacceptable entries enhanced the usefulness of the data.
Another way to make corrections during the computer editing process is substitution. Substitution is the assignment of a full set of characteristics for a person or housing unit. Because of the detailed field operations, substitution was not needed for the 2005 Census.
The 2005 Census of Palau questionnaire was designed as a keyable document. The information supplied to the enumerator by the respondent was recorded by marking the answers in the appropriate answer boxes and, in some cases, entering a write-in response.
Enumerators returned all completed questionnaires to the Census office where the questionnaires were checked and edited for completeness and consistency of the responses. Once all data collection activities were complete, the questionnaires were coded in the Census office. All write-in entries (ethnicity, relationship, language, migration, place of birth, parental birthplace, place of work, industry and occupation) were coded. After all coding operations were complete, the data entry clerks keyed all the responses to the questions on all the questionnaires using the CSPro entry package, including the codes for the write-in entries.
The disks containing the keyed data were then processed on microcomputers using the Consistency and Correction (CONCOR) package for editing the data and the Census Tabulation System (CENTS) for tabulating the data.
Coverage and Edit-Failure Follow up- The enumerators conducted an initial check of the questionnaires for completeness and consistency. The census office staff performed additional coverage and edit checks. Those households for which questionnaires did not meet specific quality standards because of incomplete information were contacted by personal visit to obtain the missing information.
Estimates of Sampling Error
Sampling Error is not applicable to full enumeration censuses.
In any large-scale statistical operation, such as the 2005 Census of the Republic of Palau, human- and machine-related errors were anticipated. These errors are commonly referred to as nonsampling errors. Such errors include not enumerating every household or every person in the population, not obtaining all required information form the respondents, obtaining incorrect or inconsistent information, and recording information incorrectly. In addition, errors can occur during the field review of the enumerators' work, during clerical handling of the census questionnaires, or during the electronic processing of the questionnaires.
To reduce various types of nonsampling errors, a number of techniques were implemented during the planning, data collection, and data processing activities. Quality assurance methods were used throughout the data collection and processing phases of the census to improve the quality of the data.
Confidentiality of respondents and their information is guarded under a confidentiality oath required of all enumerators and OPS staff involved in the undertaking of Census 2005. Further protection is guaranteed under the Statistics Act of 2011.
While public acces to aggregate Census data is permissible, the identity of respondents (persons and establishments) cannot be revealed at any time. The Statistics Act 2011 specifically inhibits any means by which the identity and privacy of respondents could be compromised with corresponding penalties.
When the dataset has been anonymized and is available as a Public Use Dataset, it will be accessible to all for statistical and research purposes only, under the following terms and conditions:
1. The data and other materials will not be redistributed or sold to other individuals, institutions, or organizations without the written agreement of the Director of Budget and Planning, Ministry of Finance.
2. The data will be used for statistical and scientific research purposes only. They will be used solely for reporting of aggregated informationand not for investigation of specific individuals or organizations.
