Social and demographic factors: formula sheet

Full chapter guide

Key formulas

Natural population change
Natural change = births − deaths
Positive means the population grows from natural causes; negative means it shrinks.
Net migration
Net migration = immigrants − emigrants
Positive means more people are arriving than leaving.
Total population change
Population change = (births − deaths) + (immigrants − emigrants)
A country can grow through migration even if births are below deaths.
Dependency ratio
Dependency ratio = (young dependants + older dependants) ÷ working-age population × 100
Age bands vary by country (commonly under 15 and 65 and over, with working age 15 to 64). Use the bands given in the question.
PESTEL letters
P + E + S + T + E + L = Political, Economic, Social, Technological, Environmental, Legal
Social is the third factor. Do not confuse it with economic factors such as income levels, interest rates and inflation.
Social factor groups
Social = Demographic (measurable population facts) + Cultural (values, attitudes, lifestyle)
Demographic examples: age structure, population size, birth rate, migration. Cultural examples: health awareness, attitudes to ethics, work-life balance.
Impact rule
Factor → Change → Effect on this business → Opportunity or threat
Use this chain for every point. A factor named without its effect earns little.

Quick revision

  • Demographics are measurable characteristics of a population, such as size, age, gender, income distribution and location.
  • An ageing population can raise demand for healthcare and leisure for older people, and can shrink the labour supply.
  • A rising birth rate can increase demand for baby products, education and housing over time.
  • Migration changes the size and make-up of the workforce and of the customer base.
  • Culture is the shared values, beliefs and customs of a group, and it shapes buying behaviour.
  • Social change can create new markets and make existing products unpopular.
  • Social responsibility means an organisation considers the effects of its actions on society, beyond making a profit.
  • Public attitudes can pressure organisations on ethics, the environment and treatment of workers.
  • In PESTEL, the S covers demographics, lifestyle, culture and social attitudes.
  • Always state the impact: demand, labour, cost or reputation.
  • Do not confuse social factors with economic ones: income levels are economic, while attitudes to saving or spending are social.

Common mistakes

  • Treating demographic factors as the same as all social and cultural factors. Fix: Demographics are measurable population statistics. Attitudes, values and fashions are cultural factors.
  • Saying an ageing population always hurts business. Fix: Give both sides. Healthcare, leisure and care providers gain demand, while employers may lose young recruits.
  • Treating social and demographic factors as the same thing. Fix: Use the counting test. Measurable population data is demographic. Attitudes, values and lifestyles are social or cultural.
  • Listing a factor without saying how it affects the business. Fix: Always add a link: factor, then effect on demand, product, marketing or staff, then response.
  • Treating social responsibility as only charity donations. Fix: Remember CSR covers how the whole business operates: employment, products, supply chain and environment, not just giving money.
  • Confusing social factors with political or legal factors. Fix: If the scenario describes people's views or behaviour, it is social. If it describes a rule or government action, it is political or legal.
  • Classing income, unemployment or inflation as social factors. Fix: Money-based conditions of the whole economy are economic. Social covers who people are and what they value.
  • Listing factors without linking them to the business. Fix: Always finish with the effect: what happens to demand, costs, staff or reputation for the named business.

Exam tips

  • Always state the direction of the trend before the effect. Marks go to the link, not the label.
  • In scenario questions, name the age group and the product or job role affected.
  • Check whether a question asks about demand or labour supply. They need different answers.
  • For calculations, use the age bands in the question and show each step, even in number entry questions where only the final figure is entered.
  • Remember demographics belong in the Social part of PESTEL.
  • In Section A, first decide whether the item is social or demographic. Many wrong answers come from mixing these up.
  • In multiple response questions, read how many options to select and pick only that number, each linked to attitudes, values or lifestyles.
  • In Section B, structure each answer as factor, effect, response. This keeps answers short and covers what the examiner wants.
