SIGNAL topic master brief: Poverty and Inequality (WEC14, spec 4.3.4)
What this is, and what it deliberately doesn't repeat
A single-topic frequency-and-pattern brief, built from a targeted re-read of
WEC14-verified-facts.md for every citation tagged to spec 4.3.4 (poverty 4.3.4.1; inequality
4.3.4.2), cross-checked against poverty-and-inequality.ts and the two existing technique-hub
documents that already touch this topic — signal-frequency-and-boundaries.md (one row each in
a paper-wide table) and codex-deep-dive-poverty-and-inequality.md (the economics and worked
numeric examples, in depth). Neither lays out every series/question citation for this topic in
one place, or states the tariff/context pattern as a standalone "what to expect" answer — that is
this document's only job. It adds no new worked examples, derivations, or causes content; see
the CODEX deep-dive and the lesson for that.
Denominator. WEC14-verified-facts.md read 14 real series (October 2020–January 2025); 13
of the 14 also carry an examiner report (June 2021 has no examiner report in the archive). All
counts below are against that 14-series base unless stated otherwise.
1. Every real citation found, by series and question
| Series | Q | Section | What was tested | Real, citable detail |
|---|---|---|---|---|
| October 2020 | Q2 | A (MCQ, 1 mark) | Reading a Lorenz-curve comparison between two countries | Well answered |
| January 2021 | Q7(c) | B (4 marks) | Explain relative poverty | Only 6% of candidates attained full marks; a named error was confusing it with absolute poverty (examiner report) |
| January 2021 | — | B (source booklet) | Global Gini coefficient, 2000–2014, used as real context | Cited as real context Pearson has used; no specific question number given in the facts file for this data itself |
| October 2021 | Q7(c) | B (2 marks, embedded in a Zambia BoP/exchange-rate booklet) | Define the Gini coefficient | Two independently creditable routes: a bare verbal definition, or "Area A / Area (A+B)" with a labelled Lorenz curve (mark scheme) |
| June 2022 | Q10 | C (20 marks) | Evaluate government policies to reduce income inequality (developing-country gate) | Examiner report: candidates who named causes instead of policies "did not attain any marks" |
| October 2022 | Q3 | A (MCQ, 1 mark) | Reading the direction of a Lorenz-curve shift (Peru) | Moderately well answered |
| June 2023 | Q10 | C (20 marks) | Causes of income inequality | Pattern confirmed in the facts file's command-word summary; not independently re-extracted to a quote-level citation in that document |
| October 2023 | Q4 | A (MCQ, 1 mark) | Deducing the Lorenz-curve direction from a fall in Georgia's Gini coefficient | The archive's one documented direction-of-shift error on this diagram |
| January 2024 | Q8 | C (20 marks: KAA 12 + Evaluation 8) | Evaluate causes of an increase in income inequality within a developed country (Sweden/USA, 2007–2022) | This paper's fullest-evidenced instance — 13 named KAA causes, a full evaluation band, and an examiner-confirmed finding that most answers stalled on a "two-stage chain" and that evaluative comments were "generic" |
| October 2024 | Q7(b) | B (4 marks) | Explain absolute poverty | Well answered |
| October 2024 | Q9 | C (20 marks) | Income-inequality causes essay | Cited in the facts file's command-word summary alongside June 2023 Q10 and January 2024 Q8; no further quote-level detail is recorded there |
Combining both sub-points, this spec point surfaces in 9 of the 14 series checked (October 2020, January 2021, October 2021, June 2022, October 2022, June 2023, October 2023, January 2024, October 2024) — poverty's bare definitions alone in 2 of 14 (January 2021, October 2024); inequality's measurement/causes content alone in 7 of 14.
2. The real mark-tariff pattern
- Poverty's definitions sit at a low, evaluation-free tariff. Both confirmed instances (January 2021 Q7(c), October 2024 Q7(b)) are 4-mark Section B "explain the term" parts, no evaluation credited — the general Knowledge-2/Application-2 slot in Section B's fixed 2+4+6+8+14 = 34-mark structure.
- Inequality's Lorenz-curve/Gini content is a stable Section A fixture. Three confirmed 1-mark MCQ instances (October 2020, October 2022, October 2023), plus one 2-mark Section B bare-definition instance (October 2021) that arrived embedded inside an unrelated balance-of-payments source booklet, not a standalone inequality question.
- Causes of income inequality is this topic's recurring 20-mark Section C slot — the highest tariff this topic reaches, confirmed in four series (June 2022, June 2023, January 2024, October 2024), always split 12 KAA + 8 Evaluation, and always carrying the standard Section C "country gate" (Level 3 KAA capped at 9/12 marks if no developed/developing country is actually named and used).
- No confirmed Section C essay was found built around poverty's own causes-of-change sub-point (4.3.4.1.c) in the sampled archive — a gap, not a confirmed absence; see the CODEX deep-dive for the same finding stated in full.
3. The recurring context/angle
- Every confirmed Section C essay and Section A MCQ on this topic anchors to a real, named country and a stated change over a real time period, never an abstract prompt: Sweden and the USA, 2007–2022 (Jan 2024 Q8); Peru's Lorenz curve (Oct 2022 Q3); Georgia's Gini coefficient (Oct 2023 Q4); a global Gini series, 2000–2014 (Jan 2021 source booklet).
- The Section C command word is not fixed to "causes." June 2022 Q10 asked for policies to reduce inequality, not causes — the examiner report shows this is a genuinely different task, and a causes-essay answer to it failed outright. Read the command word before assuming "causes" is what's wanted.
- Section A MCQs consistently test the direction of a Lorenz-curve/Gini shift, not just reading a static diagram — the one documented archive error (Georgia, Oct 2023) was a direction-of-shift mistake, not a definitional one.
4. If this topic appears — what to expect
- Section A: a Lorenz-curve or Gini MCQ, most likely reading the direction of a shift for a named real country, not just identifying which curve is which.
- Section B: a low-tariff (4-mark, no evaluation) "explain absolute/relative poverty" part is the best-evidenced single slot — and the sharpest-documented failure point on this spec point (6% full marks, January 2021). A bare Gini definition can also turn up embedded inside an unrelated source booklet (it has, once, inside a balance-of-payments booklet).
- Section C: if this topic is one of the three essay choices, expect a 20-mark, country-gated question about causes of income inequality in a real named country over a real period — but check the command word first, since "evaluate policies to reduce inequality" is a real, confirmed alternative framing that a causes-only answer will fail.
- Whichever slot it lands in, the archive's best-evidenced trap for this topic is reversing or conflating paired definitions (absolute vs relative poverty) and, at the essay tariff, substituting causes for the thing actually asked for (policies, or evaluation of causes rather than a list of them).
