The Issue Over the last 50 years, the populations of most countries in Latin America and the Caribbean have been aging steadily. An increase in life expectancy coupled with a decline in birth rates is expected to continue in the coming decades. As the proportion of the elderly population in the region increases, so too will demands for healthcare services and pension collections, as well as the number of people leaving the workforce. An aging population is often the sign of a healthy society, but countries can and should prepare for the upcoming reality of a significant demographic shift by adapting age-friendly digital solutions to help mitigate these effects and better care for the elderly. If countries start preparing now rather than waiting until they are facing an aging bulge in 30 years, they will be able to effectively manage the ensuing shifts in societal and economic demands and avoid many problems.
Recommendations Design a strategy to support a healthy aging population. This includes creating smart cities, expanding accessible public transportation, and facilitating continuing education for older adults.
Strengthen the healthcare sector. Digital initiatives like telemedicine and data-driven healthcare can help healthcare workers better care for patients with chronic illness, which is more common in old age.
Support caregivers. Caregivers in the Western Hemisphere include both professionals and family members. Digital solutions like wearable robotic devices and apps that track symptoms and medical appointments can help caregivers provide better support to older adults.
Modernize insurance and pension systems. Countries should design pension schemes and insurance systems that offer coverage to both formal and informal workers so that all employees can better access government resources and plan for their retirement. Digitization of these systems can educate people on financial planning, increase the trust populations have in their governments, and allow companies greater data-sharing capabilities, among other benefits.
Prepare the workforce. Along with a shrinking working-age population, countries are facing an increasing push toward workforce automation to replace older employees who are leaving. Many sectors, particularly in the formal economy, can benefit from automated procedures rather than relying on human capital, which further reduces the need for in-person jobs. The automation of jobs in the informal sector is nearly impossible, however, meaning that countries will continue to rely on informal workers even as the working-age population decreases. The digitalization of immigration systems can also help facilitate legal migration to fill gaps in the workforce and ensure both faster processing systems and more dependable information.
Encourage the silver economy. An older population will also bring many opportunities for the economies of countries in the region. As the population ages, more people will begin to participate in the “silver economy.” Older people are major contributors to the economy: they often have significant spending power, they travel, and they consume services like healthcare more than younger populations. Countries should prepare their workforces now for jobs in industries that older populations will use.
Strengthen the community of practice. Several multilateral organizations have already identified aging as a policy priority and are working with countries in the Western Hemisphere to prepare for an aging population. Countries in the Western Hemisphere can also benefit from the experiences of other countries with aging populations, like Japan, Greece, and Italy, to design and implement aging strategies. Aging in the Western Hemisphere As of 2019, approximately 9 percent of the Western Hemisphere’s population was over the age of 65, up from 6.8 percent just 10 years ago. This figure is expected to increase to more than to 19 percent by the year 2050 and reach 30 percent by the end of the century. Some countries in the region are aging much more quickly than others. For example, Cuba is projected to have an elderly population close to Japan’s current levels (around 28 percent) in the next 20 years, while Haiti, the youngest country in the hemisphere, will only have 10 percent of its population over 65 in 2050. Average life expectancy in the region has been steadily increasing over the past several decades, from about 60 years of age in 1970 to over 75 in 2019. The World Bank projects that life expectancy will surpass 80 years of age in the region by 2050.
Simultaneously, fertility rates in the region are going down. In 2015, the overall fertility rate in Latin America and the Caribbean fell under the standard replacement level of 2.1 births per woman for the first time. The fertility rate has continued to fall; the regional birth rate was 2.0 in 2019, and over the next 30 years, it is projected that fertility will continue to decline, averaging 1.7 birt
Population Ageing Dynamics
Curriculum Area: Geography (KS3 – Year 8)
Specific Unit: Human and Physical Geography – Population and Urbanisation
Focus: Global demographic changes with a regional focus on Latin America and the Caribbean, exploring the causes and consequences of an ageing population, and designing strategies to address challenges.
Learning Objectives
By the end of this lesson, students will:
- Understand the causes and effects of population ageing in Latin America and the Caribbean.
- Analyse the socio-economic challenges and opportunities created by an ageing population.
- Evaluate strategies for addressing ageing populations, with a focus on digital solutions, healthcare, and pensions systems.
- Work collaboratively to propose innovative and practical solutions for managing ageing populations.
Lesson Structure (60 minutes)
Starter (5 minutes)
Activity:
- Place an age pyramid of a young population (e.g., Haiti) and an ageing population (e.g., Cuba) on the board.
- Question to class: "What do you notice about the shape of these graphs? What might be causing these changes?"
Goal: Prompt curiosity and critical thinking about demographic structures.
Resource Used: Age pyramid diagrams (printed or projected).
Introduction and Context (10 minutes)
Teacher-Led Discussion:
- Introduce the concept of population ageing.
- Explain the key causes: increased life expectancy and declining birth rates, using key statistics (e.g., fertility rates, life expectancy for Latin America and the Caribbean).
- Highlight regional diversity (e.g., Cuba compared to Haiti) and the projected impacts for 2050.
- Discuss why this issue is relevant globally, tying it to the UK context (e.g., the UK’s rising ageing population and dependency ratios).
Visuals: Graphs and maps showing life expectancy trends, fertility rates, and percentage of elderly populations in Latin America versus Europe.
Group Activity: Regional Challenges (15 minutes)
Task:
-
Split students into five groups. Assign each group a challenge related to an ageing population:
- Healthcare
- Pensions and financial planning
- Workforce and automation
- Urbanisation and smart cities
- Caregiving and community support
-
Each group:
- Research their challenge using short summary cards provided by the teacher.
- Discuss the potential impacts for countries like Cuba or Brazil in the next 30 years.
Role of Teacher:
Move between groups to support discussions, ensuring students stay on task and think critically.
Output: Groups record three challenges and three potential solutions on chart paper or a digital platform if available.
Interactive Class Debate: Solutions Discussion (15 minutes)
Activity Flow:
- Each group presents their findings briefly (2 mins each).
- Class collaboratively ranks the proposed solutions for effectiveness (using a "Top 3 Solutions" approach on the whiteboard). For example, solutions for pensions might include "introducing informal worker pension schemes" or "educating populations on financial planning".
- Teacher guides students to connect proposed solutions with real-world examples (e.g., the UK’s pension reforms, Japan and smart city initiatives).
Individual Task: Personal Reflection (10 minutes)
Scenario-Based Exercise:
- Students individually respond to this prompt in their books:
"Imagine you are the mayor of a city in Latin America with an ageing population. Write a short proposal outlining two strategies you would prioritise to support older people and explain why you chose these." - Tip: Encourage students to reference what they learned in the group activity and debate.
Plenary: Key Takeaways (5 minutes)
Activity:
- Return to the initial starter activity. Show the two age pyramids again.
- Ask students, "What solutions would help Haiti prepare for demographic change as it grows older, and what could Cuba learn from Japan?"
Exit Question:
- Students answer on an exit slip or orally: "What is one thing the UK could learn from Latin America about preparing for an ageing population?"
Assessment Opportunities
- Formative: Group discussions (listening for critical analysis and engagement).
- Summative: Individual scenario-based exercise (evaluating written proposals for strategy effectiveness).
Resources Needed
- Age pyramid diagrams (Haiti and Cuba).
- Summary challenge cards for group work.
- Chart paper, markers (or digital equivalents).
- Graphs on fertility rates and life expectancy in Latin America and the Caribbean.
Differentiation Strategies
- For Higher-Attaining Students: Encourage them to think critically about the role of technology and innovation in addressing ageing issues, asking them to design a specific digital solution.
- For Lower-Attaining Students: Provide sentence starters for the reflection task and additional teacher support during group work.
- For EAL Students: Use visuals, key demographic graphs, and glossaries for complex terms (e.g., "dependency ratio", "fertility rate").
Cross-Curricular Connections
- Maths: Interpreting and analysing age pyramid and graph data.
- PSHE: Empathy and understanding of caregiving and community responsibilities.
- ICT: Exploring digital solutions to socio-economic challenges (e.g., telemedicine).
Extension/Homework Activity
- Research how the UK is addressing its own ageing population. Find one innovative solution (e.g., Age-Friendly Cities in Manchester or pension reforms) and compare it to strategies used in Latin America or Japan. Write a one-page report to be discussed in the next lesson.
This lesson plan gives students a comprehensive understanding of population ageing in a global context and empowers them to analyse problems creatively and collaboratively, aligning with KS3 Geography curriculum objectives while preparing them for critical thinking in broader societal contexts.
