Survey and research incentives in Africa — disbursing without bank accounts

Survey response rates in Africa are highly sensitive to incentive reliability. A respondent who has learned that promised payments don't arrive stops completing surveys. The data quality problem and the payment infrastructure problem are the same problem.

Market research, academic studies, public health surveillance, NGO programme monitoring — all of these require collecting data from people, and increasingly all of them offer some form of compensation for respondents' time. In high-income markets, disbursement is a solved problem: PayPal, gift card email delivery, bank transfer. In African markets, none of these defaults work reliably.

PayPal has limited reach. Bank transfers require account details you don't have and take days. Email delivery assumes a functioning email address and reliable internet access. And cash disbursement via field enumerators introduces the full set of problems — delays, leakage, safety risks, and a paper trail that doesn't satisfy most donor or IRB reporting requirements.

The respondent profile reality

Most surveys conducted in African markets aim to reach respondents who are representative of the population, not just the digitally connected elite. That means:

• →A significant proportion of respondents won't have a bank account — financial inclusion rates in countries like Niger, Mali, and Madagascar remain below 30%.
• →Even respondents with bank accounts may not have the account details readily available or may distrust sharing them with an unknown research organisation.
• →Smartphone and data access is unevenly distributed — any incentive delivery mechanism requiring a data connection will fail for a portion of respondents.
• →Mobile money (M-Pesa, MTN MoMo, Airtel Money) has high penetration in East and West Africa and is the closest thing to a universal payment rail — but wallet registration and name matching introduce friction.

Incentive disbursement is not a logistics problem. It's a data quality problem. Respondents who trust that payment arrives complete surveys honestly. Those who don't, don't complete them at all.

Disbursement mechanics that work

The most reliable incentive disbursement path for African research uses the respondent's phone number as the only identifier required, and SMS as the delivery channel, with USSD as the redemption channel for those without data access.

• 1.Airtime delivery via SMS: Respondent completes survey, phone number is captured (or already on record for panel members). Airtime is delivered to that number within minutes. No wallet registration, no bank account, no action required beyond receiving the SMS.
• 2.Gift card via SMS: A reward code is sent by SMS. Respondent can redeem via USSD or web portal. Slightly more steps than airtime but allows choice of reward category and higher face values.
• 3.Mobile money via SMS notification: Payment initiated to respondent's mobile money wallet. SMS confirms receipt. Requires respondent to have a registered wallet on one of the covered networks.

Timing and panel retention

For one-off surveys, timing matters for completion rates. The incentive promise should be made at the start of the survey (not hidden in the thank-you page), and delivery should happen within 24 hours of completion. For panel-based research — where the same respondents are invited to multiple studies over time — incentive reliability is the primary driver of panel retention rate.

A panel where incentives consistently arrive within a day of survey completion will have significantly higher response rates to future surveys than one where payments arrive late or inconsistently. This is not a small effect — response rates on reliable panels can run 3–5x higher than panels with a history of payment issues.

Recommended incentive values by survey type

• →5-minute consumer survey: ₦200–500 airtime equivalent. Low friction, covers the time cost.
• →20-minute household survey: ₦500–1,500 gift card. Justifies the time investment.
• →1-hour in-depth interview or FGD: ₦2,000–5,000 gift card or mobile money. Meaningful compensation for meaningful time.
• →Longitudinal / panel participation: Accumulating rewards per wave plus a panel loyalty bonus at 12 months creates strong retention incentives.
