Abstract
The Household Income and Expenditure Survey (HIES) is a field operation which consists of collecting information in the households based on face to face interview.
The questions asked to the households are related to living standard conditions, expenditures, purchases, incomes.... It is the only survey conducted at a national level which deals with households habits in terms of expenditure and income. As the private and public sector, households represent an economic and social actor of the country which needed to be known.
The purpose of the HIES survey is to obtain information on the income, consumption pattern, incidence of poverty, and saving propensities for different groups of people in the Solomon Islands.
This information will be used to guide policy makers in framing socio-economic developmental policies and in initiating financial measures for improving economic conditions of the people.
Some more specific outputs from the survey are listed below:
a) To obtain expenditure weights and other useful data for the revision of the consumer price index;
b) To supplement the data available for use in compiling official estimates of household accounts in the systems of national accounts;
c) To supply basic data needed for policy making in connection with social and economic planning;
d) To provide data for assessing the impact on household living conditions of existing or proposed economic and social measures, particularly changes in the structure of household expenditures and in household consumption;
e) To gather information on poverty lines and incidence of poverty throughout the Solomon Islands.
The previous HIES was conducted in 2005-2006, 7 years ago. All the indicators based on this survey need to be updated now.
a) In the CPI, new items have appeared on the market since 2005, and the purchases habits / consumption habits of the household has changed
b) The poverty assessment of the country has to be updated as well, based on the household living condition in 2012 (job opportunities have changed, income, education level...)
c) In terms of national account, this survey will provide aggregates of 2012 household consumption.
This survey will highlight the level of expenditure and income of the households, situation with employment, equipment, assets of the households, education and health information, source of income and remittances...
It will derive indicators that would provide Solomon Islands Government and their development partners with a core set of statistics to facilitate evidence-based policy development and planning, to monitor development progress and measure policy performance, and ultimately to describe development impact.

b) Who has been living in the Solomon Islands less than 12 months ago but plan to stay in the country for more than 12 months
Whatever their origin, ethnicity, composition, activity, occupation, the concept of private household excludes all kind of communities (hospital, boarding school, military compound).

Sampling
Sampling Procedure
The objective is to survey 4608 households. These households interviewed cannot be chosen by the field staff, but have to be randomly selected from all provinces of the Solomon Island.
In order to obtain 4608 households, we have to select a larger sample, in case of replacement.
For this reason the sample size is increased by 50% (2304 households) to 6912 households. This selection comes from a 2 stages process:
STAGE 1: SELECTION OF EAs
An EA (Enumeration Area) is an area defined for the census, delimited by natural or artificial boundaries (river, seaside, road...). In this area, between 50 and 150 households are located. All the EA are classified according to an EA ID of 7 digits:
Each province is divided in wards, and each ward is divided in EAs. The EA's ID is made of province code + ward code + EA code.
a) Province Code - 2 digits
b) Ward Code - 2digits
c) EA code - 3 digits
The HIES sample was made of 384 Enumerations Areas randomly selected with probability proportional to their size in terms of number of households based on the Solomon Islands census 2009.
The stratification allowed a better distribution of the sample across the country as follow. In each province, 4 areas have been designed according to their remoteness:
1. Urban: urban are of all the provinces
a) Honiara city (province1 is all urban
b) No urban are defined in Rennel Belona province
2. Near rural: rural areas with easy access to urban areas
3. Far rural: rural area far from urban areas
4. Remote rural
5. Out of scope: too difficult to reach (Asimae, Luaniua, Pelau and Sika'iana in Malaita and Tikopia, Ynesian and Duff Islands in Temotu).
STAGE 2: SELECTION OF HOUSEHOLDS
The households are selected by the supervisors from the listing of all the households inhabited of the EA. The first task of the team consists in walking into the EA and marking all the households who live within the boundaries of the EA.
The objective is to survey 4608 households in total. In order to complete this task, there was a need to increase the selection by 50%, in case of replacement (refusal, household not available...).
In each EA, 18 households are selected in total:
- 12 households in list A: the one to contact in priority
- 6 households in list B: to contact in case of replacement
If for any reason, some households from list A need to be replaced, supervisors has to select households selected in list B
In total, 4608 are selected in list A, to contact in priority, and 2304 in list B, to contact in case of replacement.
Detailed information of the sample selection could be found in the 'Field Work Instruction Manual' and 'Household Weights Computation Report' attached in the External Resuorces folder..

Detailed information of the sample selection could be found in the 'Field Work Instruction Manual' and 'Household Weights Computation Report' attached in the External Resuorces folder..
Deviations from the Sample Design
For some extreme reasons, some teams could not reach the selected EA (Enumeration Area) which lead to some EA replacements.
Major reasons for not reaching these EAs include bad weather, relocation of population, access difficulty and some were not recommended for security reasons.
In total, 7 EAs were replaced due to the above reasons. Both Western and Guadalcanal remote strata could not be reached by the team and have been replaced with EAs from rural2 strata.
There were 9 EAs that were lost and nor replaced due to:
a) Termination of Supervisors due to disciplinary reasons.
b) Tsunami
Details of the specific EAs could be found in the 'Househols Weights Computation Report'

Response Rate
The response rate for each stratum were:
-Choiseul - 100%
-Western - 99%
-Isabel - 100%
-Central - 100%
-Rennel Bell - 100%
-Guadalcanal - 96.7%
-Malaita - 99.8%
-Makira - 100%
-Temotu - 74%
-Honiara - 99.5%
-TOTAL - 97.2%
In total, 97.2% of the scheduled sample were interviewed. Temotu province had the lowest completion rate due to the tsunami that hit the province in February 2013. The whole phase 2 (4 rounds out of 16 - from roud5 to round8) of the Temotu province were cancelled. (96 households lost).
Guadalcanal had only 96.7% of completion rate due to the lack of supervision in one of the team. The entire round8 of Guadalcanal team3 were lost when the supervisor of this team was fired as he decided to run away with the laptop and the forms, 12 households lost.
Other province did not complete 100% of the expected schedule due to invalid forms. Some households did not returned the diary or some modules were lost, which made some forms unacceptable for analysis and dropped from the database (see completion report).

Weighting
The weight of one household interviewed is computed using the inverse of its probability of selection.
Solomon Islands Household Income and Expenditure Survey (HIES) 2012/2013 sample is a 2-stages sample selection:
a) Stage1: selection of Primary Sampling Unit (Enumeration Areas or EAs): Prob1
b) Stage2: selection of households within the EAs: Prob2
-Prob1 = Number of HHs in the EA * (number of EAs to select in the strata / total number of households in the strata)
-Prob2 = Number of households to select in the EA / Total number of households listed within the EA
As 18 households per EA have to be randomly selected by the supervisors based on the updated list of households (done by the team the first day of the round) and 12 of them have to be interviewed, Prob2 shows up as:
Prob1 = 18 / Total number of households listed within the EA * (12 / 18)
Prob2 = 12 / Total number of households listed within the EA
Weight = Prob1 * Prob2.
