High Frequency Phone Survey on COVID-19 2022, Round 1
1-2-3 Survey, phase 1 [hh/123-1]
The World Bank is providing support to countries to help mitigate the spread and impact of the new corona-virus disease (COVID-19). One area of support is for data collection to inform evidence-based policies that may help mitigate the effects of this disease.
To monitor the socio-economic impacts of COVID-19 in Vanuatu, five rounds of High Frequency Phone Survey on COVID-19 (HFPS) are planned. The documented dataset refers to the first round of the HFPS of Vanuatu.
The phone survey was conducted to gather data on the socio-economic impact of COVID-19 crisis in Vanuatu. Community transmission of COVID-19 in Vanuatu started only in March 2022 followed by the nation-wide lockdown and other restrictions. Round 1 HFPS survey was a timely process to observe the effect of the crisis on the country. Round 1 interviewed 2,515 households both in urban and rural regions of the country from July 2022 to September 2022.
Survey topics included employment and income, food security, coping strategies, access to health services, and asset ownership - all on household level. Additionally, two individual-level datasets explore adult employment and child education. The former selects a randomly chosen adult in the household - could be the respondent of a household-level data, head of the household or another individual - and inquires about their employment status. For the latter, the respondent is being asked about education of a randomly chosen child in the household with more than one child.
While these findings are not without their caveats due to the lack of baseline data, constraints of the mobile phone survey methodology, and data quality constraints, they represent the best estimates to date and supplement other data on macroeconomic conditions, exports, firm-level information, etc. to develop an initial picture of the impacts of the crises on the population.

The Vanuatu HFPS Round 1 sample was generated in three ways. The first method is Random Digit Dialing (RDD) process covering all cell telephone numbers active at the time of the sample selection. Majority of the sample was generated through RDD in this round - approximately 84%.
The RDD methodology generates virtually all possible telephone numbers in the country under the national telephone numbering plan and then draws a random sample of numbers. This method guarantees full coverage of the population with a phone.
First, a large first-phase sample of cell phone numbers was selected and screened through an automated process to identify the active numbers. Then, a smaller second-phase sample was selected from the active residential numbers identified in the first-phase sample and was delivered to the data collection team to be called by the interviewers. When a cell phone was called, the call answerer was interviewed as long as he or she was 18 years of age or above and knowledgeable about the household activities.
The remaining 16% of Round 1 respondents was retrieved from Vanuatu's National Sustainable Development Plan (NSDP) Baseline Survey 2019/20.
Total of 9,674 calls were attempted for Round 1. Response rate - where the phone was picked up - was 40%. Out of these, 66% completed the full survey.

Data Collection Notes
The survey management team of Sistemas Integrales included a Project Director, a Project Manager, and an Operations Manager. The data collection was implemented with a team formed by three field coordinators, 2 supervisors and 22 interviewer. The average interview time for 158 question-long survey was 37.96 minutes.

The questionnaire was developed in both English and Bislama. Sections of the Questionnaire are listed below:
1. Interview Information
2. Basic Information
3. Vaccine Information
6. Food Insecurity
9. Coping Strategies
The questionnaire is provided in this documentation as an external resource.
At the end of data collection, the raw dataset was cleaned by the survey firm and the World Bank team. Data cleaning mainly included formatting, relabeling, and excluding survey monitoring variables (e.g., interview start and end times). Data was edited using the software Stata.
For consistency purposes, all categorical levels were labeled identically across variables, where applicable. Each dataset has its own weight variable used for data processing. For the household dataset, "wta_hh" is used for household-level analysis. For the adult employment individual-level analysis "empl_weight" should be used. Child weights - "chi_weight" - represent weights for children aged 5-17 and should be used for child-level analysis.
