demographic changes at local, national and global level

6.1 External Influences – Social and Demographic

Demographic changes shape the way businesses operate. They tell us who the customers are, how many of them there are, and where they live. Let’s explore these changes at local, national and global levels using simple analogies, clear examples and handy exam tips.

Local Level Demographic Changes 📍

Think of a local community like a small garden. The number of plants (people) and the types of plants (age groups, income levels) determine what kind of tools (products/services) the gardener (business) needs.

  • Population growth or decline in a town or city.

  • Age structure – proportion of children, working-age adults, and seniors.

  • Household size and composition.

  • Migration patterns – people moving in or out.

YearPopulationGrowth Rate
201045,0000.5 %
202048,5001.0 %
2030 (proj.)52,0001.2 %

Exam Tip: When asked about local demographic changes, mention population growth rates and age structure, and explain how these influence product demand and service needs.

National Level Demographic Changes 🇬🇧

A country’s demographic profile is like a national sports team: the mix of players (age groups) and their skills (skills/education) determine the team’s strategy (economic policy).

  1. Birth and death rates – shape the natural increase.

  2. Immigration and emigration – alter the net migration figure.

  3. Urbanisation – movement from rural to urban areas.

  4. Fertility trends – number of children per woman.

Indicator20192024 (proj.)
Total Population (millions)67.068.5
Fertility Rate (children/woman)1.661.60
Net Migration (thousands)+550+600

Exam Tip: Highlight the interaction between birth rates, death rates, and migration when explaining national demographic trends. Use the population pyramid as a visual aid if allowed.

Global Level Demographic Changes 🌍

The world’s population is like a giant orchestra. Each country contributes a different instrument (age mix, fertility) and together they create the global rhythm of growth.

  • Population size – currently over 8 billion.

  • Growth rate – slowing in many developed regions, still high in parts of Africa and South Asia.

  • Urbanisation – more than 55 % of the world lives in cities.

  • Ageing – the proportion of people aged 65+ is rising worldwide.

RegionPopulation (millions)Growth Rate
Asia4,6001.0 %
Africa1,3002.5 %
Europe741-0.1 %

Exam Tip: For global questions, compare growth rates across regions and discuss the implications for global supply chains and market opportunities.

Key Take‑aways

  • Local demographics influence product mix and store locations.

  • National trends affect labour market and consumer spending.

  • Global shifts shape international trade and investment flows.

  • Use population pyramids and growth tables to visualise data.
