# Underserved Population

An underserved population is a group of people or small businesses with little or no access to mainstream financial services: the unbanked, who have no account, and the underbanked, who have one but still rely on cheque cashers, payday lenders or informal credit because banks' products, prices or checks do not fit them. Financial-inclusion policy and many fintech models target it.

**Also known as:** Underserved communities, Financially excluded, Unbanked and underbanked, Underbanked population

## Key facts

- **Scale worldwide:** the World Bank's Global Findex 2025 found that 79% of adults had an account in 2024, up from 51% in 2011; 1.3 billion adults still had none
- **Scale in the US:** the FDIC's 2023 household survey found 4.2% of households — about 5.6 million — unbanked; not having enough money to meet minimum balance requirements was the most-cited reason, distrust of banks the second
- **Common barriers:** identity documents, minimum balances and fees, distance from branches, thin or missing credit files, irregular income, language and distrust
- **Policy levers:** the EU Payment Accounts Directive (2014/92/EU) gives consumers legally resident in the EU a right to a basic payment account with a credit institution; FATF guidance allows tiered, simplified due diligence for low-limit products; the US Community Reinvestment Act rates banks on serving low- and moderate-income neighbourhoods
- **Channels that reach them:** mobile money, e-money and prepaid accounts, agent networks, remittance providers, and credit scoring on alternative data

## How serving an underserved population works in practice

Serving this market is a cost problem before it is a marketing one. Balances are small and irregular, so an account run through branches and paper loses money; fintechs make the economics work with mobile onboarding, no branches, and revenue from interchange, remittance fees or credit rather than account fees. Mobile money showed the model, and the World Bank notes that 86% of adults now have a mobile phone and that many of the unbanked already hold the phone, ID and registered SIM a digital account needs.

Onboarding is the first gate. Customers without a passport, a utility bill or a fixed address fail standard KYC checks. FATF guidance lets countries allow "tiered" accounts, with low transaction and balance limits and simpler checks, which can be upgraded as the customer's identity is verified further.

Credit is the harder product. Without a credit file, lenders use alternative data — rent, utility and telecom payments, account cash flows — and learn quickly how much of their early losses were mispricing and how much fraud. The line between inclusion and predatory lending is thin, and regulators watch pricing, collections and complaints.

For an investor, a company serving underserved customers is priced on unit economics that must survive small balances: acquisition cost, share of active accounts, credit losses, and whether revenue depends on fees a regulator could cap.

## Example

A US fintech opens no-fee accounts with debit cards for hourly workers, a third of them previously unbanked, and acquires 400,000 customers at $35 each. An active customer brings in about $6 a month from debit interchange and optional early wage access and costs $1.50 a month to serve; 55% are still active after a year, and the cohort pays back its acquisition cost in about ten months. The next step is credit: $300 lines scored on six months of account cash flows. The first lending cohort loses 11% of balances against the 6% priced, most of it on accounts opened with synthetic identities. The company tightens onboarding checks and device screening before scaling the product, and the loss rate on the next cohort falls to 7%.

## Common mistakes

- Pricing products for underserved customers from the economics of mainstream ones.
- Treating every thin-file applicant as high risk, or every one as safe because a model says so.
- Building the core revenue line on overdraft or late fees that regulators may cap.
- Onboarding with checks that exclude the target customers, or with none that stop synthetic identities.
- Counting sign-ups as inclusion when most accounts go dormant within months.
