3.3.5 Comparing Economic Systems — research prep

Unit 3 · Culture · Lesson 3.3 Economics

The big idea This activity is a real research task — you look up data for one developed country (Singapore), one developing country (Peru), and one least-developed country (Uganda), then reason about what the numbers show. The table asks specifically for HDI ranking 2024, sourced from the UN's Human Development Report 2023–24 snapshot. This page cannot do that lookup for you and won't guess at the numbers. It reviews exactly what each measurement means and exactly where the activity points you to find them, so the research itself goes fast.

By the end you can

  • Know what each requested measurement actually represents, before looking it up.
  • Use the UN Human Development Report and CIA World Factbook correctly, including the PPP warning.
  • Reason about whether HDI alone tells the whole story of quality of life.

Before you start: what PPP is actually adjusting for

The whole activity hinges on this one idea. Get it clear first and the research goes much faster.

Check the required research source first (2)

Before filling those columns, confirm which archived edition or replacement source your teacher accepts. Record the year and basis of every figure. Keep the HDI ranking column tied to the activity’s 2023–24 report snapshot.

HDI combines health, knowledge and income per person.
Keep the assigned HDI source separate from the other indicators.

What you're filling in, and why each column matters

The table asks for six measurements on Singapore, Peru, and Uganda — one from each development tier (developed, developing, least developed):

What you're filling in, and why each column matters (2)

HDI ranking 2024 — the table's own label. This is the country's overall rank on the Human Development Index, combining health, knowledge, and wealth into one number, sourced from the UN's Human Development Report 2023–24 snapshot (the report that publishes the "2024" ranking the table wants).

What you're filling in, and why each column matters (3)

Life expectancy and world ranking — the average age someone in that country can expect to live to, and how that ranks worldwide.

What you're filling in, and why each column matters (4)

Infant mortality rate and world ranking — how many infants per 1,000 live births die before age one; a core health-care-quality signal.

What you're filling in, and why each column matters (5)

Adult literacy rate — the percentage of the adult population that can read and write.

What you're filling in, and why each column matters (6)

Real GDP and world ranking — the country's total economic output, and how that ranks worldwide.

What you're filling in, and why each column matters (7)

Per capita GDP and world ranking — total GDP divided by population, showing the average person's slice of that wealth.

What you're filling in, and why each column matters (8)

Real GDP and per capita GDP can rank very differently for the same country — a big population can produce a large total GDP while each person's share stays small. The other five measurements don't have a stated year the way HDI ranking does — different parts of the CIA World Factbook and the UN report get updated on their own schedules, so write down the year or edition each figure comes from as you fill in the table, rather than assuming everything is from the same "2024" snapshot.

Likely on the quiz Notice the table deliberately separates total GDP from per-person GDP, and raw rate from world ranking. Each pair tells a different part of the story — don't collapse them into one number. And don't assume every number in your table shares one vintage; record the year for each one.

The PPP warning — don't mix your sources

The activity gives one very specific warning: all GDP figures must be compared on a purchasing parity basis (PPP) — adjusted so prices for the same goods and services are comparable across countries, since a dollar buys more in some countries than others. Your sources may label this "GDP (PPP)." The activity's own caution: don't use the plain GDP figure from one country and the GDP (PPP) figure for another in the same comparison — that mixes two different kinds of measurement and makes the comparison meaningless.

The PPP warning — don't mix your sources (3)

The activity names the World Factbook for the other measurements. Its old site now redirects to the CIA’s retirement announcement. Use an archived edition or replacement only after confirming that source for this assignment.

The PPP warning — don't mix your sources (4)

Both report PPP-adjusted figures; check which one each site is showing you before you copy a number into your table.

Likely on the quiz Before you write any GDP number into the table, check it says "PPP" (or an equivalent purchasing-power note) next to it — and make sure every GDP figure in your table uses the same basis.

The three questions that come after the table

Once your table is filled in with real current numbers, the activity asks you to reason from it, not just report it:

The three questions that come after the table (2)

1. What does the life expectancy and infant mortality data say about the general quality of health care in these three countries?
2. What does comparing the adult literacy rates show you?
3. What does the gap between a country's overall GDP ranking and its per-capita GDP ranking tell you?

The three questions that come after the table (3)

Then a formal paragraph: does the HDI ranking of a country, by itself, actually tell you the full story of quality of life there? This is the same question 3.3.4 raised when it pointed out that HDI leaves out sanitation, water availability, political freedom, and social stability.

Health, knowledge, and income per person combine in the Human Development Index.
The three dimensions of HDI. HPI and GEM are separate measures.
Likely on the quiz Question 5 wants a real position with evidence, not just "yes" or "no." Your own table — especially anything HDI doesn't capture, like a gap between real and per-capita GDP — is your evidence.
