The latest of a series of national population and housing censuses (NPHC) of Solomon Islands was held in 1999. The results were of acceptable quality and standard and were consulted by civil servants at local, provincial and national levels, by businessmen and non-governmental organisation, as well as by overseas investors and aid organisation. They used the available information for daily administration and for planning and policy making. By analysing the response to the 1999 census questionnaires and comparing the data with the 1970, 1976 and 1986 census results, the census office was able to make good estimates of levels of fertility, mortality and internal migration as well as produce a range of population projections at national and sub-national levels. The population growth rate of 2.8 per cent per annum in the 1986-1999 inter-census-period, paradoxically is a reduction but still remains as amongst the highest in the world. With this very high growth rate the Solomon Islands Government could not afford to continue its laissez-faire policy concerning population issues, hence a continuous monitoring of the growth rate at regular intervals, through the census process, should be maintained and a review of the current population policy should also be taken.
The 2009 Census falls within the 2010 Round of Pacific Census, ten years after the 1999 census.
The results of the 2009 census will be required to:
a. help produce high-quality information for planning, decision-making, and monitoring of development progress in Solomon Islands. This implies very heavy data requirements and these requirements are continuously increasing, particularly towards development planning, implementation monitoring and evaluation of Government policies outlined in NERDEP and the current Medium Term Development Strategies.
b. The data from the Census will also be used for monitoring the achievement of the Millennium Development Goals (MDG's) and other goals included in the International Conference for Population & Development (ICPD).
c. check whether the population policies, which were put in place after the 1986 census on the basis of 1976-86 population trends and then as reviewed in the early 2000s in respect of the 1999 population trends, proved effective, and
d. Establish a new benchmark and a new set of post-1999 population trends on which to base a reconsideration of existing (population) policies in the framework of sustained and sustainable development.
e. Also, the results of this census will help facilitate updating of constituencies in preparation to the 2010 national election of Solomon Islands.
f. Further to these, the results of the census will provide a sample Frame from which further household capability surveys which include a household income expenditure in 2010/2011, a second demographic and health survey (DHS) 2011/2012 and a Labour Force Survey before the next census can be undertaken.
g. The 2009 census will also provide the much needed village level data on population, resources and infrastructure for government's bottom-up approach development policy initiative.
Accepting the notion that a new census is required and that a number of overseas aid organisations will be able to support the government on an undertaking similar to the 1999 census, the following points are considered in more detail in this project proposal.
It is recommended that the present census interval should not exceed ten years and that the same month should be selected in 2009, for the period of enumeration as in 1999, mainly to ensure that seasonal factors would not reduce the comparability of the information provided by the two censuses. As a result of this recommendation, 22nd November 2009 is therefore proposed as the new census date. This date will be formally announced by the Prime Minister in line with the Census Act.
For making current administrative decisions and prepare longer term socio-economic development policies governments and private organisations need reliable up-to-date knowledge about available natural and human resources. In a country like Solomon Islands one of the most important statistical systems for obtaining the required socio-economic information is the population census. This does not only provide a numerical description of the population at a given census date - through comparison with previous census results - but also of the ongoing trends in a sustained and sustainable development of certain population characteristics such as changes in population growth, age composition, direction of mobility and levels of urbanisation, economic activities and educational status. Such knowledge may allow the development planner to devise policies that will stem the flow of trends considered not in line with development aims. Alternatively, trends considered fitting can be identified and fostered by the introduction of appropriate policies. The success thereof can then be assessed when a next census is held some ten years later.

Data Collection Notes
Census was started with Household listing which counts all the Houses and household Units and also was captured by GPS (Geographical Positioning System) as to locate their localities as in waypoints and areas of living.
Census Household listing have about 105 personals working as Enumerators,Area Managers and Census Districts Superintendent.
After the Household listing,Census office conducted Pilot Census as to Pre-Test the Census draft Questionnaires with about 70 Enumerators.
After all these,thus finalise all questionnaires,logistics and etc for the Acutaully census on November 2009.
1 PHASE I: PRE-ENUMERATION PERIOD
The period culminating in the actual enumeration in November 2009 started with the establishment of a Census Office in Honiara in October/November 2008. The Census Commissioner seconded from the Statistics Office supported by a Secretary, a high-graded Post Finance (Accounts) Officer seconded from SIGAS, Census Statistician, Cartographer and Data Processing Officer - all Solomon Islanders - are to prepare for the conduct of a household listing of each village, a pilot census, the production of maps and village lists of each Enumeration Area (EA) and, the design and printing of questionnaire, manuals, record books, the purchase of equipment for the office and field staff; the recruitment of staff; the establishment of short term training centres; the preparation of training manuals and aids; the planning and execution of a transport schedule to gather supervisors and enumerators in the training centres, transport them to their EA's and later return them home; the publicity needed to make the whole population aware of the census and of the information they are asked to supply. All these tasks have to be done in a particular sequence and be completed strictly before certain dates. The census effort therefore requires utmost co-operation from all parties involved, authorities at various levels, private organisations and the village and urban populations. To foster the support needed for this purpose the Census Commissioner should report to the Census Users Committee at various critical stages of the project and seek concurrence for his planned activities.
In the 1976, 1986 and 1999 censuses the enumeration was done following a two-visit system. Each enumerator was required to visit all households (on the average about 60 households) in his/her Enumeration Area (EA) in the two weeks before census night and enumerate the people found there. The enumerator was then to return directly after census night to cross out any previously enumerated people who did not sleep in the household that night and add to the household any persons, who were not previously interviewed, but had slept in the household on the Census night. It is assumed in this project proposal that this system be continued in the 2009 census.
The Census Office should have the staff to carry out the tasks briefly described above. It is envisaged to divide the nine provinces and one main urban area (Honiara) into seven census districts (CD). In each of these a census districts, a census districts superintendent (CDS) should be made responsible for the proper execution of all preparatory work and of the actual conduct of the enumeration, in full consultation with the Census Commissioner. The CDS's, most or all of whom should be Solomon Islanders, would have to work closely with the provincial authorities and need the assistance of Chief Area Managers (CAM) and or the Area Manager (AM) depending on the level of work and where these personnel's are deployed. The CAM and AM will check in the field, the EA maps drafted in the Census Office on the basis of information of the Village Resource Survey (conducted by the Statistics Office in November 2007 to April 2008); supervise the conduct of a full household listing; explain the census in village meetings; prepare a transportation plan for his area; help in recruiting supervisors and enumerators; play active roles in their training and in co-ordinating their transport and work during the actual census enumeration.
There will be approximately 1611 EA's and therefore a need for 1611 trained enumerators and for 266 supervisors. All of these personnel must be trained (taking into account 20 per cent reserves for 'no-shows' and 'dropouts'), the supervisors in six (6) centres and the enumerators in 14 centres. Temporary assistance will be needed from the authorities to provide professional trainers as well as a few higher level staff to act as Directors of some of the training centres, which will last for eight and five working days for the supervisors and enumerators respectively. Obviously, the Trainers, Directors and the Quality Controllers (who are to help screen completed forms before they will be returned to Honiara for data processing) should also be trained and this will equally apply for longer term staff, i.e. Census Office staff, CDS's, and AM's who will have their own courses earlier in the year. The high level staff can participate in special courses if the need arises, however, these types of training is expected to be provided by the CTA, as part of an on-the-job training activity of the Census.
2. PHASE II: POST-ENUMERATION PERIOD
In this phase the census returns will have to be processed, tabulated, analysed and disseminated in the form of published reports. It is argued, that while in previous censuses data processing was largely done overseas the time is now ripe to carry out all the required work locally. This includes the following steps:
i. Preparation of the code-scheme, tabulation lay-outs, creation of a test file, system design for the various processing steps and testing of these systems.
ii. Arrangements of office space, furniture and equipment.
iii. manual checking of the returned forms, transportation of the information into numeric codes on the forms, manual compilation of provisional small area statistics for early release as per 2010 National General Election requirements and correction of EA maps and village listings.
iv. Scanning of the questionnaires on scanners to create a complete computer data file of the census information; this will then be transferred into defined data dictionary using CSPro. With two scanners and 24 staff, four groups of 6 persons each will operate the scanners in two shifts per day for two months.
v. Remaining erroneous codes are to be checked by a checking section of five persons verifiers working with two PC's, who are to detect the underlying reasons for errors, devise ways to correct them and, for a limited number of variables, change wrong or not stated codes by imputation.
vi. The tabulation section is to produce various types of tables (e.g. 'ad hoc' tables, provincial tables, publication tables, and work tables, tables on request of users and cartograms, which all should be carefully scrutinised for consistency between them.
vii. The specialised member of the census project will subsequently analyse the quality of the reported census data and by comparison with previous census data, establish past trends, which can then serve as indicators for probable future developments. Specialised computer packages will be used for this purpose and much attention will have to be given to presenting the conclusions in comprehensive, but readable texts.

1. QUESTIONNAIRE AND SCANNING
The need to set up the questionnaire in terms of suitability for local printing have done, using a software package called in-design, or whatever is most appropriate, which will then allow “optimisation ” for scanning with check boxes, drop-out colours (colours which are then filtered out by the scanner) etc. It is important that the questions are laid out correctly to make sure the results of the scan are possible and legible and eligible or recorded. Prior to the pilot census, the questionnaire needs to be finalised and come up with something everyone is happy with, finalise it and then make sure it works (if questions/formatting needs amendments as a result of the pilot, such changes will of course be done).
The questionnaire was finalised and a reliable printer to print the questionnaires was sought in advance through the tender bidding process. There are a whole series of things the Census office need to check here to make sure that the job gets done to a sufficient standard and that the scanning works well (good quality machines, paper, ink, air conditioned operating environment etc). There was no printing company in Honiara who can do this thus the printing done in Australia
In addition the questionnaire develop and were all in English language as people normally understand the english reading than the Solomons pidgin.The quetionnaire was design in Adobe Illustrator as to make sure the lines and writtings all well linned and parallel to what had written.Hence the census form have to have the right color which the scannning has to read and can easily collect the characters and values.
As such the census forms had been well protected while in field and properly manage in a way which the forms will not distroyed easily by rain or sea.
Hence,the census questionnaire covers Households and Housing.All Persons and GPS,more detailed in Scope section.
Data editing took place at a number of stages throughout the processing, including:
a) After Scanning data exported to CSPro4.0 edited done by data proccessing officer.
b) Secondly the Data proccessing officer pass the data to Data verifiers
c) Structure checking and completeness by verifiers in terms of wrong written numbers and spellings
d) Batch editing:
- Variables out of range
- Fertility Questions
- Coding and Value sets
- Editing of Variables..eg.age,date of birth and etc.
Detailed documentation of the editing of data can be found in the "Data processing guidelines" document provided as an external resource.
The design of the data processing system should include, in the data entry operation, a series of checks and automatic corrections, which should be based on very stringent specifications devised by the SPC-TA and data processing manager. In the first place it must be ascertained, that the identity codes (Provinces, Wards, EA's, Villages) of the households and persons are complete, not multi-entered and in agreement with the manually calculated figures. Secondly, checks are needed ensuring that there are neither invalid out-of-range codes, nor codes of one person which do not tally with other codes of the same person or with relevant codes of other persons in the same household. If the error rates prove to be below a certain (low) level the erroneous codes could be automatically replaced by improved ones if these can be deducted from other data in the household or from frequency distributions of the relevant variables in a wider area of from random distributions. The imputation of new values for erroneous or not stated codes is particularly important for the variables sex and age as they affect most tabulations to be produced later. For other variables imputation of erroneous or not stated cases is generally less important and in the absence of clear indications about their true values codes can be made or left "not stated". After a statistical report on the number of errors (by variable, type of error, and area) the data entered for the relevant EA is then to be accepted for entry in the census data file. However, if in the keyed-in EA an error rate above the acceptable level is found and if errors occurred in the geographic identity codes of households the EA data should be sent to the data checking team.
Data Entry process:
1. Census office received completed incoming census forms.
2. Census office Registered by province and EAs.
3. Registered Census forms sealed and Transfer to Census Data room for recording as received by data proccessing.
4. Dated and scanning started.
5. After Scanning completed Census forms Sealed in plastics and properly place and arrange by Province in shelves.
6. The arrangement will be easy for hard copy checking and verify.
