Look at the photograph. Bus companies carry passengers, shops sell goods that others have made, and phone companies sell airtime. None of them grows or makes anything, yet together they are the largest part of Rwanda’s economy. In 2025 services produced 52% of GDP, according to NISR, and employed 44.4% of all employed people, according to its Labour Force Survey. Both shares are larger than those of agriculture or industry.
The table shows the main service branches in 2025.
| Service branch | Change in output, 2025 | Share of all employed, 2025 |
|---|---|---|
| Wholesale and retail trade (with vehicle repair) | +15% | 15.0% |
| Transport and storage | +7% | 7.0% |
| Education | +5% | 4.2% |
| Hotels and restaurants | −2% | 3.9% |
| Public administration | +6% | 1.7% |
| Health and social work | −13% | 1.0% |
| Financial services and insurance | +7% | 0.9% |
| Information and communication | +15% | 0.4% |

Definition
Tertiary sector (service sector): the sector that provides services, not goods, to people and businesses, such as trade, transport, banking, insurance, communication, education, health and tourism.
Service: an activity done for someone that satisfies a want but cannot be stored or touched, such as a bus ride, a haircut or a lesson.
Example: a moto rider carrying a passenger produces a service; the motorcycle itself was produced by the secondary sector.
Commercial services help goods move from producers to consumers. Trade is the buying and selling itself; the other commercial services are called aids to trade, because each one removes an obstacle, or hindrance, that would stop trade.
Direct services, also called personal services, are given straight to people to satisfy their wants: teaching, health care, hairdressing, legal advice, security, entertainment and guiding tourists. Some are provided by the state (public services, such as government schools and the police); others by private businesses.
Definition
Commercial services: services that help goods pass from producers to consumers: trade and the aids to trade.
Aids to trade: services that remove the hindrances to trade: transport, warehousing, banking, insurance, advertising and communication.
Direct (personal) services: services given straight to people to satisfy their wants, such as those of teachers, nurses, barbers and lawyers.
Wholesale trade: buying in large quantities from producers and selling to retailers. Retail trade: selling in small quantities to final consumers.
Tip
Memory hook. Match each aid to the problem it solves: far → transport; not yet needed → warehousing; no money → banking; might be lost → insurance; nobody knows → advertising; can’t talk → communication. Exam questions often describe the problem and ask you to name the aid.
Worked example 1: which aid to trade?
| Situation | Aid to trade | Hindrance removed |
|---|---|---|
| Maize harvested in July must last a mill until the next harvest. | warehousing | time |
| A trader in Rusizi needs Frw 2 million to buy stock before customers pay. | banking (a loan) | lack of money |
| A lorry of goods could be damaged in an accident. | insurance | risk |
| A new bakery in Huye has no customers who know about it. | advertising | lack of information |
| Potatoes grown in Musanze are wanted in Kigali. | transport | distance |
Method: name the problem first, then the service that solves it. The businesses are illustrative.
Worked example 2: where do service workers work?
Use the table above. (a) What percentage of all employed people worked in trade, transport, or hotels and restaurants? (b) What fraction of the service workers is that?
(a) of all employed.
(b) Services employed 44.4%, so
Interpret. More than half of Rwanda’s service workers are in these three branches, many of them in small shops, transport and eating places. Information and communication grew by 15% in 2025 but employed only 0.4% of workers: a branch can grow fast without employing many people.
Tertiary Sector: Types of Services!, from the Mr. Sinn channel. Watch for the types of service the video names, then find a Rwandan business for each and decide whether it is a commercial or a direct service.
Warning
Common mistakes. (1) Putting a market seller in the primary sector because she sells vegetables: selling is trade, a tertiary activity. (2) Thinking that services matter less because nothing is made: the tertiary sector is the largest sector in Rwanda by output and by employment. (3) Mixing up wholesale and retail: the difference is whom the trader sells to, retailers or final consumers, not how big the shop is.
