Tertiary Activities: Trade, Transport, Communication and Services
When you fall ill, you visit a doctor. When you study, your teacher delivers a lesson. When a contract goes wrong, a lawyer drafts a notice. When you ride a bus, a driver moves you. None of these workers digs ore from the earth (a primary task) or stamps a sheet of metal in a factory (a secondary task) — yet without them no economy can run. They form the giant service sector, the tertiary activities. This part of Chapter 6 explores what tertiary activities are, why their share of jobs and GDP rises as a country develops, and the four families inside the service sector — trade, transport, communication and services.
📜 Chapter Opening Idea
Tertiary activities are related to the service sector. Manpower is an important component of the service sector as most of the tertiary activities are performed by skilled labour, professionally trained experts and consultants. In a developed economy, the majority of workers get employment in tertiary activity and a moderate proportion is employed in the secondary sector. Tertiary activities involve the commercial output of services rather than the production of tangible goods. They are not directly involved in the processing of physical raw materials.
— NCERT, Fundamentals of Human Geography (Class 12)
6.1 What Are Tertiary Activities?
Tertiary activities? are economic activities that provide services rather than tangible goods. A service is a special skill or expertise made available in exchange for payment. When your parents take you to a hospital for treatment, when a teacher coaches you through a difficult chapter, when a lawyer files a petition on your behalf, or when a banker arranges a home loan, you are consuming a service — and paying for it through fees, premiums or salaries. Health, education, law, governance and recreation all require professional skills, and these skills depend on theoretical knowledge and practical training.
The textbook definition is therefore precise: tertiary activities are "related to the service sector", and manpower is the most important component of this sector because most tertiary work is performed by skilled labour, professionally trained experts and consultants. Common examples include the work of a plumber, electrician, technician, launderer, barber, shopkeeper, driver, cashier, teacher, doctor, lawyer and publisher. The output of these workers is intangible — a healed patient, a coached student, a delivered parcel, a haircut — and is indirectly measured through the wages and salaries paid to them.
📖 Definition — Tertiary Activities
All services are special skills provided in exchange of payments. Tertiary activities involve the commercial output of services rather than the production of tangible goods, and they are not directly involved in the processing of physical raw materials. They include both production (the provision of services that are consumed) and exchange (trade, transport and communication facilities used to overcome distance).
SVG — The Four-Tier Hierarchy of Economic Activities
Figure 6.1: The five-tier hierarchy of economic activity. Each tier rests on the one below — but as a country develops, more workers move upward into services and knowledge work.
Why the Service Sector Grows With Development
NCERT puts it plainly. "In the initial stages of economic development, larger proportion of people worked in the primary sector. In a developed economy, the majority of workers get employment in tertiary activity and a moderate proportion is employed in the secondary sector." The graph of any developing economy follows the same path. India in 1950 had over 70 per cent of its workforce in agriculture; by 2024 the share of services in GDP exceeds 50 per cent and continues to climb. As people get richer, they spend a larger share of their income on services — schooling, healthcare, travel, entertainment, financial advice — and the demand pulls more workers in.
The contrast with secondary activities is sharpest at the level of what each worker brings. A factory worker uses production techniques, machinery and factory processes to make a product. A service worker uses specialised skills, experience and knowledge. The expertise provided by services "relies more heavily on specialised skills, experience and knowledge of the workers rather than on the production techniques, machinery and factory processes." A surgeon's hand, a barrister's argument, a teacher's voice — these are the tools of the tertiary economy, and they cannot be stamped out on an assembly line.
💡 White-Collar, Blue-Collar, Red-Collar
Service workers are popularly called white-collar workers? because their work is desk-based, indoor and clean — a contrast with the blue-collar factory worker (secondary) and the red-collar primary worker. The colour code is informal but useful: white for office services, blue for factory floor, red for outdoor extraction, gold for top decision-makers, grey for technicians, pink for care/personal services. We will meet the gold-collar quinary worker in Part 2.

Figure 6.2: The collar-colour atlas. Every economy has all five (or more) groups; only the proportions differ.
6.2 Types of Tertiary Activities
NCERT divides the service sector into four families: trade and commerce, transport, communication and services proper. Together they cover almost everything you do that is not farming or factory work. The illustration in Figure 6.3 lays out the entire family tree.
SVG — The Service Sector Tree
Figure 6.3: The service-sector tree. Every tertiary worker fits somewhere on this chart.
6.3 Trade and Commerce
Trade? is essentially buying and selling of items produced elsewhere. All the services in retail and wholesale trading or commerce are specifically intended for profit. Towns and cities where these activities concentrate are called trading centres. The history of trade runs from local barter to international money-exchange, and along the way it has produced an entire architecture of collection points, distribution points and marketing institutions.
A. Trading Centres — Rural and Urban
NCERT splits trading centres into two great categories.
Rural Marketing Centres
Cater to nearby settlements. They are quasi-urban centres — local collecting and distributing points where personal and professional services are not yet well-developed. Most have mandis (wholesale markets) and retailing areas. They are not urban centres per se, but they make available the goods and services most often demanded by rural folk.
Periodic Markets
In rural areas where no regular market exists, periodic markets are organised at different intervals — weekly or bi-weekly — gathering the surrounding population's accumulated demand. They are held on specified dates and move from one place to another, so traders remain busy all the days while a large area is served.
Urban Marketing Centres
Provide more specialised urban services. They offer ordinary goods and the specialised goods and services demanded by city-dwellers — markets for labour, housing, semi-finished and finished products. Educational institutions, lawyers, consultants, physicians, dentists and veterinary doctors all cluster here.
From Barter to Money
The rise of trading "from barter at the local level to money-exchange of international scale" has produced collection and distribution points, banks, exchanges, customs houses and free-trade zones. Modern global trade is the apex of this evolution.
B. Retail Trading
Retail trading? is the business activity concerned with the sale of goods directly to the consumers. Most retail trading takes place in fixed establishments — stores solely devoted to selling. But a parallel and growing world of non-store retailing uses street peddling, handcarts, trucks, door-to-door, mail-order, telephone, automatic vending machines and the internet.
| Form | How It Works | Strength | Indian / World Examples |
|---|---|---|---|
| Consumer Cooperatives | Owned by member-consumers; first of the large-scale innovations in retailing | Lower prices through bulk buying for members | Kendriya Bhandar (India), Apna Bazar, Sahakari Bhandar |
| Departmental Stores | Delegate authority to departmental heads for buying and overseeing sale in different sections | One-stop shopping under one roof | Shoppers Stop, Westside; Harrods (London); Galeries Lafayette (Paris) |
| Chain Stores | Buy most economically, sometimes directing goods to be made to their specification; experiment in one store, apply to many; employ highly skilled executives | Massive scale economies, branded uniformity | Reliance Fresh, Big Bazaar, Walmart, Carrefour, 7-Eleven |
| Supermarkets / Hypermarkets | Self-service stores stocking food + household goods | Convenience & low prices on staples | D-Mart, Spencer's, Tesco, Costco |
| Shopping Malls | Cluster of branded shops, restaurants, cinemas | Recreation + retail in one trip | Phoenix Marketcity, DLF Mall of India, Mall of America |
| Traditional Bazaars / Mandis | Open-air or covered cluster of stalls | Cheap, lively, local | Chandni Chowk (Delhi), Crawford Market (Mumbai), Khari Baoli |
| E-commerce | Internet-based non-store retail | 24×7 access, doorstep delivery, vast selection | Amazon, Flipkart, Myntra, Meesho, Alibaba |
| Other Non-Store | Vending machines, door-to-door, mail order, telephone | Reaches niche or remote customers | Tupperware (D2D), Eureka Forbes, Amway |
💡 The E-Commerce Revolution
E-commerce — buying and selling through the internet — is the most disruptive non-store retail form of our time. India's e-commerce market grew from a few hundred crore rupees in 2010 to over ₹8 lakh crore in 2024, with Amazon, Flipkart, Meesho and Reliance JioMart leading the way. Live-streaming on Instagram and WhatsApp Catalogues have folded social media into retail, creating "social commerce".
C. Wholesale Trading
Wholesale trading? constitutes bulk business through numerous intermediary merchants and supply houses and not through retail stores. Some large stores, including chain stores, can buy directly from manufacturers; most retail stores procure supplies from an intermediary. Wholesalers often extend credit to retail stores to such an extent that the retailer largely operates on the wholesaler's capital.
| Feature | Wholesale | Retail |
|---|---|---|
| Customer | Other businesses (retailers, factories) | End consumers |
| Quantity | Large bulk lots | Small individual units |
| Margin | Low margin per unit, high volume | Higher margin per unit, lower volume |
| Examples | Mandis, cash-and-carry warehouses, Metro Cash & Carry | D-Mart, Big Bazaar, kiranas, Amazon |
| Credit | Often extends credit to retailers | Mostly cash / card / UPI |
Chart — India's Sector Share of GDP, 1950–2024
Figure 6.4: As India developed, the share of services in GDP rose from under 30% in 1950 to over 50% by 2024. Agriculture (primary) shrank steadily; industry (secondary) plateaued.
LET'S EXPLORE — Map Your Local Trading Ecosystem
Bloom: L3 Apply
Walk through your nearest neighbourhood and list five different retail forms you can identify within 1 km — a kirana, a supermarket, a chain store, a mall, an e-commerce delivery rider. For each, note who the customer is and what kind of goods are sold. Which form do you and your family use most often, and why?
✅ Pointers
A typical urban Indian neighbourhood will have: a kirana shop (traditional bazaar form, family-run), a D-Mart or Reliance Fresh (chain store / supermarket), a cycle-cart vegetable seller (non-store retail), an Amazon delivery van (e-commerce), a chemist (specialised retail). Most families use a mix — kirana for daily essentials (relationship, credit), supermarket for weekly bulk (price, choice), e-commerce for non-perishable bargains (selection, doorstep).
6.4 Transport & Communication (in Brief)
Transport? is a service or facility by which people, materials and manufactured goods are physically carried from one location to another. It is an organised industry created to satisfy man's basic need of mobility. Modern society needs speedy and efficient transport systems to assist in the production, distribution and consumption of goods. At every stage of this complex system, transportation significantly enhances the value of the material — a banana on the farm is worth less than the same banana on a Mumbai shelf because transport has added utility of place.
Transport distance can be measured three ways: as km distance (actual length of the route), as time distance (the time taken to travel), or as cost distance (the expense of travelling). In selecting a mode of transport, distance in terms of time or cost is the determining factor. Isochrone lines are drawn on a map to join places that are equal in terms of the time taken to reach them — a Mumbai-centred isochrone map might place Pune (3 hours by Expressway) closer than Nashik (4 hours by NH-3).
📖 Networks & Accessibility
As transport systems develop, different places are linked together to form a network. Networks are made of nodes and links. A node is the meeting point of two or more routes — a point of origin, a point of destination, or any sizeable town along a route. Every road that joins two nodes is called a link. A developed network has many links, which means places are well-connected.
Factors Affecting Transport
Demand for transport is influenced by population size — the larger the population, the greater the demand. Routes depend on the location of cities, towns, villages, industrial centres and raw materials, the pattern of trade between them, the nature of the landscape between them, the type of climate, and the funds available for overcoming obstacles along the length of the route. (We return to specific modes — road, rail, water, air, pipeline — in Chapter 7: Transport and Communication.)
Communication
Communication services? involve the transmission of words and messages, facts and ideas. The invention of writing preserved messages and tied communication to means of transport — letters carried by hand, animal, boat, road, rail and air. That is why all forms of transport are also referred to as lines of communication. Where the transport network is efficient, communications are easily disseminated.
Twentieth-century inventions changed this. Mobile telephony and satellites have made communications independent of transport. Yet not all forms have been fully disassociated, because of the cheapness of older systems — very large volumes of mail continue to be handled by post offices all over the world.
Telecommunications
Linked to the development of modern technology, telecommunications have revolutionised communications because of the speed with which messages are sent — from weeks to minutes. Mobile telephony has made communications direct and instantaneous any time and from anywhere. The telegraph, morse code and telex have almost become things of the past.
Mass Media
Radio and television relay news, pictures and telephone calls to vast audiences worldwide and are termed mass media. They are vital for advertising and entertainment. Newspapers cover events in all corners of the world.
Satellite Communication
Satellites relay information of the earth and from space. They make remote television, weather observation, GPS navigation and global telephone networks possible.
The Internet
The internet has "truly revolutionised the global communication system" — combining text, voice, video and data in a single, on-demand, world-wide medium. It is the backbone of e-commerce, e-governance, e-learning and the modern knowledge economy.
6.5 Services — A Closer Look
Services occur at many different levels. Some are geared to industry, some to people, and some to both — for example, transport systems serve both freight (industry) and passengers (people). NCERT recognises a hierarchy:
Low-Order Services
Common and widespread — grocery shops, laundries, barbers, mechanics. Their threshold (minimum customers needed) is small, so they appear in every neighbourhood.
High-Order (Specialised) Services
Less common, more specialised — accountants, consultants, physicians, neurosurgeons. Their threshold is large, so they cluster in cities where many customers can afford their fees.
Physical-Labour Services
Workers like the gardener, the launderer and the barber primarily do physical labour. Their tools are simple, their skills practical and their charges modest.
Mental-Labour Services
Teachers, lawyers, physicians and musicians perform mental labour. Their training is long, their skills cognitive, and their fees correspondingly higher.
A. Personal Services
Personal services are made available to people to facilitate their daily life. Workers migrate from rural areas in search of employment and are often unskilled. They are employed in domestic services as housekeepers, cooks and gardeners. This segment of workers is generally unorganised. NCERT highlights one famous Indian example — Mumbai's dabbawala (Tiffin) service, which delivers home-cooked meals to about 1,75,000 customers all over the city every working day with near-perfect reliability.
B. Professional Services
Professional services are primarily health care, engineering, law and management. They are delivered by trained experts — doctors, engineers, lawyers, chartered accountants, architects, management consultants — who charge a fee for their specialised knowledge.
C. Financial Services
The financial sector covers banking, insurance, stock markets and credit. Banks accept deposits and lend money; insurance firms pool risks; stock exchanges (BSE, NSE) trade ownership of companies; and modern fintech apps (Paytm, PhonePe, Google Pay) layer digital services on top of all of the above. Most of NCERT's "high-order" service hierarchy lives here.
D. Information Services
Information services include news media, magazines, websites, news channels, advertising agencies and content creators. The internet has expanded this group dramatically — bloggers, YouTubers and podcast hosts now sit alongside journalists and book publishers.
E. Recreation & Government
The location of recreational and entertainment services? depends on the market. Multiplexes and restaurants might find a location within or near the Central Business District (CBD), whereas a golf course would choose a site where land costs are lower than in the CBD. Theme parks, sports stadiums, film studios, OTT platforms and gaming all belong here.
Many services have been regulated. Making and maintaining highways and bridges, maintaining fire-fighting departments, supplying or supervising education and customer-care are among the important services most often supervised or performed by governments or companies. State and union legislation have established corporations to supervise and control the marketing of services such as transport, telecommunication, energy and water supply.
6.6 Tourism — A Special Case
Tourism is travel undertaken for recreation rather than business. It has become the world's "single largest tertiary activity in total registered jobs (250 million)" and accounts for about 40 per cent of the total GDP in many regions worldwide. Many local persons are employed to provide services like accommodation, meals, transport, entertainment and special shops serving the tourists. Tourism fosters the growth of infrastructure industries, retail trading, and craft industries (souvenirs).
In some regions, tourism is seasonal because the vacation period depends on favourable weather; in others, visitors come all year round. The warmer places around the Mediterranean Coast and the West Coast of India are some of the most popular tourist destinations in the world. Other tourist regions include winter sports regions in mountainous areas (the Alps, Himalayas, Rockies), and various scenic landscapes and national parks. Historic towns also attract tourists, because of monuments, heritage sites and cultural activities.
| Attraction | What Tourists Seek | Examples |
|---|---|---|
| Climate | Warm, sunny beach weather; or snow for skiing | Mediterranean (long sunshine, low rainfall, peak holiday season); Switzerland (skiing) |
| Landscape | Mountains, lakes, sea coasts, unaltered scenery | Alps, Himalayas, Norwegian fjords, Andamans |
| History & Art | Picturesque or ancient towns, archaeological sites, castles, palaces, churches | Rome, Paris, Agra (Taj Mahal), Hampi, Athens |
| Culture & Economy | Ethnic and local customs, cheap stay | Home-stay in heritage homes of Goa, Madikere and Coorg (Karnataka) |
🌐 Mobility of Services
Services are more mobile than goods. A factory's output (a bag of cement) can only move from where it was made; but a tourist service "moves" by bringing the customer to the provider. A doctor's expertise moves through telemedicine. Software moves over the internet. This mobility is one reason the service sector grows so much faster than manufacturing in a globalised world.
6.7 People Engaged in Tertiary Activities
Today most people are service workers. Services are provided in all societies. But in more developed countries a higher percentage of workers is employed in providing services as compared to less developed countries. The trend in employment in this sector has been increasing, while it has remained unchanged or has been decreasing in primary and secondary activities.
The four largest cities of India — Delhi, Mumbai, Chennai and Kolkata — are now overwhelmingly service economies. Most jobs in these metros are in trade, transport, banking, IT-enabled services, education, healthcare, government, hospitality and entertainment. The shift is the macroscopic signature of every developed economy on Earth.
THINK ABOUT IT — Why Do Services Cluster in Big Cities?
Bloom: L4 Analyse
NCERT's logic is straightforward: high-order services like neurosurgeons, investment bankers and architects need a large threshold population who can pay for their expertise. Why does a small town rarely have a cardiac surgeon, but a metropolitan city has dozens? List three reasons.
✅ Pointers
(1) Threshold population: a cardiac surgeon needs hundreds of paying patients per year — only a city has the volume. (2) Agglomeration economies: hospitals, diagnostic labs, pharmacies and insurers are nearby in the city, lowering operating costs. (3) Talent and amenities: highly trained specialists prefer cities for further training, social networks, schools for their children and lifestyle. The same threshold logic explains why luxury malls, top law firms, IB analysts and design studios all crowd into a handful of metros.
SOURCE-BASED — From the NCERT Box on the Dabbawala Service
Bloom: L2 Understand
"One such example in India is Mumbai's dabbawala (Tiffin) service provided to about 1,75,000 customers all over the city."
What category of service does the dabbawala work belong to? Why is it celebrated as a model of efficient, low-cost personal service?
✅ Answer
The dabbawala work is a personal service (NCERT Section "Services") combined with elements of transport. The workers are mostly migrants from rural Maharashtra, largely unskilled, and the segment is unorganised. Yet the system delivers approximately 1,75,000 tiffins across Mumbai daily with near-perfect reliability — a Six-Sigma level of accuracy that has been studied by Harvard Business School. It is celebrated as proof that low-cost personal services can deliver world-class operational performance.
📝 Competency-Based Questions — Part 1
Scenario: A District Industries Centre wants to map the tertiary activities in your district. It has data on shops, transport operators, telecom towers, banks, hospitals, schools, hotels and tourist sites. The team needs to (i) classify each activity correctly, (ii) understand why some services cluster in the city and others scatter into villages, and (iii) propose policy moves that match each tier of the service sector.
Q1. Which one of the following is a tertiary activity?
L1 RememberAnswer: (B) Trading — Trading is part of trade and commerce, the first family of tertiary activities. Farming and hunting are primary; weaving is secondary.
Q2. The District Centre proposes opening one neurosurgery hospital in the district headquarters and one general clinic in every village. Justify both decisions using NCERT's hierarchy of services (high-order vs low-order).
L3 ApplyModel Answer: A general clinic is a low-order service — common, widespread, with a small threshold of patients required to remain viable. NCERT lists "grocery shops and laundries" as parallels. Such clinics fit every village. Neurosurgery, by contrast, is a high-order specialised service like NCERT's "accountants, consultants and physicians". It needs a large catchment population, expensive equipment, and a trained surgical team — possible only in a big urban centre such as the district headquarters where the threshold is met. The two decisions together create a service hierarchy: routine care close to people, specialised care in the city.
Q3. Compare wholesale and retail trading on at least four NCERT-defined parameters and give one Indian example of each.
L4 AnalyseModel Answer: (i) Customer: wholesale serves other businesses; retail serves end consumers. (ii) Quantity: wholesale moves bulk lots; retail moves single units. (iii) Margin: wholesale is high-volume / low-margin; retail is lower-volume / higher-margin. (iv) Credit: NCERT explicitly notes that "wholesalers often extend credit to retail stores to such an extent that the retailer operates very largely on the wholesaler's capital"; retail is mostly cash/digital. Examples — wholesale: Azadpur Mandi (Delhi vegetables), Metro Cash & Carry. Retail: D-Mart, kiranas, Amazon.
Q4. The team is asked: "Why do services and the share of services in GDP rise as a country develops?" Build a 4-step argument.
L5 EvaluateModel Answer: Step 1 — Income shift: as average incomes rise above subsistence, households spend a smaller share of income on food and a larger share on healthcare, education, finance, travel and entertainment. Step 2 — Mechanisation: tractors and combines free workers from farms; automation thins out factory floors. Released labour migrates to services. Step 3 — Specialisation: a complex modern economy needs lawyers, accountants, doctors, designers and managers — none of whom existed in subsistence economies. Step 4 — Globalisation: services cross borders cheaply (software, finance, tourism, telemedicine), so a developing country like India can specialise in IT services for the world. Together these forces explain why "In a developed economy, the majority of workers get employment in tertiary activity."
HOT Q. Design a 3-tier "service-cluster plan" for a fast-growing tier-2 Indian town that wants to attract IT firms, tourists and a regional hospital. Identify the locational logic for each tier.
L6 CreateHint: Tier 1 — High-order CBD cluster: regional multi-specialty hospital + corporate offices + financial district near the railway station and airport (high-order services need a large catchment and accessibility). Tier 2 — IT & KPO park on the city outskirts with broadband, peri-urban land, talent housing — classic footloose location logic that needs only road, fibre and air. Tier 3 — Tourism circuit: heritage walks + home-stays + a multiplex-and-restaurant CBD strip + a low-cost golf course on cheap peri-urban land (recreation services with mixed location requirements). Connect all three tiers with a city bus / metro spine and a 24×7 internet backbone — the service ecosystem in 3 layers.
⚖️ Assertion–Reason Questions — Part 1
Options:
(A) Both A and R are true, and R is the correct explanation of A.
(B) Both A and R are true, but R is NOT the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
(A) Both A and R are true, and R is the correct explanation of A.
(B) Both A and R are true, but R is NOT the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
Assertion (A): Tertiary activities are not directly involved in the processing of physical raw materials.
Reason (R): The expertise provided by services relies more heavily on specialised skills, experience and knowledge of the workers rather than on production techniques, machinery and factory processes.
Answer: (A) — Both true and R is the correct explanation. NCERT explicitly contrasts tertiary work (skill-driven) with secondary work (machine-driven and material-driven), in exactly these words.
Assertion (A): In a developed economy, the majority of workers are employed in the tertiary activity.
Reason (R): As the economy develops, the share of agriculture in employment falls and the demand for services like banking, healthcare, education and tourism rises.
Answer: (A) — Both true and R is the precise reason. NCERT's structural-shift argument is the textbook macroeconomic explanation for the global "service economy" trend.
Assertion (A): Wholesalers often extend credit to retail stores.
Reason (R): The retailer largely operates on the wholesaler's capital, especially in price-sensitive small businesses.
Answer: (A) — Both true and directly linked. NCERT puts the relationship as: "Wholesalers often extend credit to retail stores to such an extent that the retailer operates very largely on the wholesaler's capital."
Frequently Asked Questions
What are tertiary activities in geography?
Tertiary activities provide services rather than producing goods — trade, transport, communication, banking, insurance, education, health, tourism, entertainment and government administration. They form the service sector.
What is the difference between retail and wholesale trade?
Retail trade sells directly to consumers in small quantities — shops, supermarkets, online stores. Wholesale trade sells in bulk to retailers and businesses — mandis, distributors, importers and stockists.
What are the types of services?
Low-order services like grocery shops, laundries, repair; high-order services like banking, insurance, professional consultancy, higher education and medical specialists. High-order services have larger trade areas.
What is the role of tourism in tertiary activities?
Tourism is a fast-growing tertiary activity and major source of foreign exchange and employment. Tourists travel for leisure, business, sport, religion, health, culture and adventure. France, Spain, USA, Italy and China lead.
What are the modes of transport?
Four major modes — land (roads, railways, pipelines), water (inland and oceanic), air (domestic, international), and pipelines (oil, gas, water). Each has specific advantages in cost, speed, capacity and reach.
What is communication and how is it different from transport?
Communication transfers information without physical movement of goods, while transport carries materials and people. Modern communication uses radio, TV, telephones, internet, satellites and instant messaging.
What are people-related and goods-related services?
People-related services include education, healthcare, beauty, fitness, entertainment. Goods-related services include transport, storage, packaging, distribution, advertising and marketing.
