Terms Of Reference : Engagement Of Survey Firms For The Nassp Scale-Up Validation And Enumeration Into The Rapid Response Register (RRR) (Lot 1-6 Data Structuring, Field Validation and Enumeration on Output Based Disbursement (ODB) plan.)

1.     Background

The Government of Nigeria has prioritized social protection interventions as a key strategy towards reducing poverty and socio-economic vulnerabilities in the country and has partnered with the World Bank under a National Social Safety Nets Project (NASSP) to expand safety nets to poor and vulnerable populations.

The development objective of the National Social Safety Nets Project for Nigeria is to provide access to targeted transfers to poor and vulnerable households under an expanded national social safety nets system. NASSP has two components;

  1. to establish the building blocks of a safety net system for the delivery of targeted support to poor households across Nigeria; and
  2. implementing a targeted cash transfer to targeted poor and vulnerable households included in the NSR, by delivering regular and reliable transfers in a way that is accessible to beneficiaries and with benefit levels that are consistent with project objectives.

The impact of COVID-19 pandemic has been dire for poor and those at-risk of falling into poverty, such as non-traditional poor-itinerant informal urban workers, and daily wage earners across Nigeria. It is against this background that the Federal Ministry of Humanitarian Affairs, Disaster Management and Social Development and the Management of the World Bank agreed to scale up NASSP to reach the urban poor not previously captured into the National Social Register (NSR).

The Rapid Response Register (RRR) is designed to capture the urban poor as one of the components of the scale-up, and a sub-component of the NSR. The “Rapid Response” as the name implies, requires urgent and meticulous approach. Whereas the National Social Register (NSR) has covered over 600 LGAs across the 36 states and FCT, the register is largely made up of the rural poor and hence, the need for the RRR to focus primarily on the urban poor and vulnerable population. The clusters of locations where these populations, in the urban and semi urban settlement live, have been identified using innovative technical inputs in combination with satellite imagery for the NASSP scale up intervention. The NASSP scale-up approach utilized existing database of Telecommunication firms; projected population from the 2006 national census figures by the National Population Commission (208 Million Nigerians as of the year 2019); the national poverty head counts established from the national living standard survey (NLSS) 2019; as well as the Nigerian Communication Commission (NCC) estimated 196 Million GSM subscriber base, as of June 2020 – most of whom (phone subscribers) are concentrated in urban areas. These databases were put to critical consideration in the design of the RRR.

The RRR approach for identifying urban poor and populations at-risk of falling into poverty were subjected to pilot test using a quick dissemination of bulk SMS/USSD to subscribers that enables data aggregation and structuring according to pre-defined benchmarks for urban poverty metrics, and the analysis and extraction of list of potential beneficiaries.

  • Rationale

The approach and methodology structured for the implementation of the RRR is relatively novel and uses a multi-stage approach, one of which includes data validation and enumeration process. This process facilitated equitable targeting, based on evidence from data and global best practices. The exercise is designed to capture respondent’s data, validate and enumerate household heads or alternates/care givers using Computerized Assisted Personal Interview (CAPI) tool with pre-loaded checklist.

The validation exercise provides a physical validation of the respondents who have responded to the USSD application and enables the elimination of respondents who may have provided false details on the application to increase their possibility of being enrolled in the program. Enumeration is the process of enlisting the validated respondents with their respective demographics and other variables that will be provided by the checklist

NASSCO is hereby seeking to engage survey firms, to undertake field survey services, to conduct data validation and enumeration exercise. The Firms will work in line with the scope of work outline in 2.0 below.

The successful survey firms will work closely with the State Operations Coordination Unit (SOCU), an affiliate of the National Social Safety-Nets Coordinating Office (NASSCO) at the state level and would ensure 100% coverage. Using a uniform validation mechanism, the firms will lead the data collection at the states. Once the data from the USSD is validated, enumerated and accepted by SOCU, the enumerated data will be shared with NASSCO, where it will be subjected to further due diligence process before it is aggregated into the Rapid Response Register.

  • Aim and Objectives

The aim of the data validation exercise is to ensure effective targeting and efficient allocation of resources to appropriate beneficiaries. Other specific objectives include:

  • To develop adequate framework for validation and enumeration of targeted poor and vulnerable household using the available primary data of Telco’s infrastructure and facilities especially through Short Message Services (SMS) and Unstructured Supplementary Service Data (USSD).
  • To effectively target and register poor and vulnerable household using the developed targeting framework as in objective 1 above.
  • To carry out data synthesis and structure of the collected feeds ensuring data quality and interoperability.

2.  Scope of Work

The Rapid Response Registration will focus on a settlement within the defined target ward as identified by the NASSP targeting categorization for urban poor and vulnerable, with a total population of 20,196,650 across the Six geo-political zones of the country. The selected firms will collect information on specific variables of interest within those political zones as defined by NASSCO for the purpose of establishing the Rapid Response Register. The sampling frame to be surveyed by each firm has been finalized and will be shared with the survey firms.

2.1. Duties and Responsibilities

Additionally, the firms will work under the following scope:

  1. The Firms under the supervision of NASSCO will adopted computer enabled data collection toolkit for enumeration successfully used during the pilot.
  2. The firms, under the supervision of NASSCO and hand holding of SOCU, will use the data collection toolkit to undertake respondent validation and enumeration, including the geo-reference of respondents’ residence.

The Survey Firms would provide to NASSCO a field procedure plan, including enumerators training plan. The field procedure plan should outline in detail all aspects of the field work to be conducted by the Survey Firms in validating and collecting the relevant data.

The responsibilities of the survey firm include the following:

  3. GPS coordinates of all respondents, labelled with the respondent’s unique ID.

6.   Special Terms & Conditions/ Specific Criteria

       i.     Survey Checklist

There will be one survey instrument for each respondent. The survey will ask questions about demographic details (but only for the head of household), socio-economic background, agricultural and business experience, financial capabilities, and intra-household decision-making. It is expected that one interview will take about 30mins, with time per interview potentially decreasing as enumerators gain experience.

Note: Caregivers contacts or Bank Account can be provided but only with the consent of the Head of the household.

      ii.     Training

Before the start of the data collection, an enumerator training will be conducted in order to familiarize the enumerators and supervisors with survey protocols and the handling of tablets. After the training, the questionnaire will be tested and optimized. This phase also serves to give a pre hands-on experience of the enumerators and logistics of the data collection process before mobilizing to the field for the exercise.

The survey firms will produce a training and field manual suitable for the local context in consultation with NASSCO/SOCU. If necessary, the training materials and field manuals will be translated to local languages.

A comprehensive general training should be given to the supervisors and enumerators in order to create a team environment and to allow for substitution between roles should any team member take a leave of absence due to illness or other emergency. Because the training should also serve as a screening process for skilled enumerators, the survey firms should recruit more enumerators for the training than will be ultimately hired for the project. The supervisors should receive supplemental training as needed.

The training should be scheduled for 3 workdays for all enumerators in a centrally placed location in Nigeria. The training program should include:

  • Theoretical component: Training should include a review of the theory of the checklist on each item specified to ensure that the enumerators and supervisors fully understand the objective of requirement. Standard quantitative interviewing techniques and field protocols should also be covered.
  • Classroom practice: Training should include individual and group exercises for enumerators to become familiar with the practice of asking survey questions and filling in questionnaires. This part of the training may include in-class demonstrations, where the checklist is projected, and one enumerator completes the checklist in front of the classroom. Finally, the trainees should conduct drill interviews on the same subject, and have the enumerators fill in a checklist for the interview to test consistency across the enumerators.

De-briefing: a one-day debriefing following the drill with the entire survey team as well as the field coordinators.
