英検1級・ILO非公式雇用57.9％と失業の違い【2026】独自24修正・4択12問

結論：英検1級のILO統計で重要なのは、informal employment（非公式雇用）とunemployment（失業）、self-employment（自営業）、違法就労を混同しないことです。ILOの2026年レビューでは、2025年の世界の就業者の57.9％が非公式雇用でした。これは世界人口全体や失業者の割合ではありません。慶英会では誤った論証を正す独自24例・4択12問・全解答を作成しました。学術長文の分母や制度的な定義、英作文の過剰な断定を同時に学べます。

一次情報：ILO｜The World of Work and the 2030 Agenda: A Ten-year Review（2026）、ILOSTAT｜Decent Work Reality Check: Informality。2026年公表・2025年の就業者統計という関係を明記します。本教材は労働の統計的な意味を扱い、特定個人の雇用関係や適法性の法律判断ではありません。試験形式は英検1級公式案内をご参照ください。

重要な5つの概念の違い

英語	意味・注意点
informal employment	制度上の保護・適用が不十分な雇用を含む
informal sector	事業・経済主体に関する分類でありinformal employmentと同義ではない
unemployment	職に就いていない状態であり、非公式雇用は就業に含まれる
self-employment	自営業。正式な制度に適用されている場合もある
illegal activity	個々の法令違反。非公式性という統計区分と同義ではない

意見論述・面接で使う8つのモデル回答

面接想定Q1

Question: Should governments support informal workers?

Model answer: Yes, policies can improve access to appropriate protection without assuming that all informal workers are unemployed.

面接想定Q2

Question: Does informality mean illegal employment?

Model answer: No. The statistical concept and the legal status of a particular activity must be considered separately.

面接想定Q3

Question: Can registration solve every problem?

Model answer: Registration may help but cannot guarantee stable income or full social protection.

面接想定Q4

Question: Why do definitions matter in global statistics?

Model answer: Different categories and denominators can produce misleading comparisons if they are confused.

面接想定Q5

Question: Should small vendors face the same requirements as large firms?

Model answer: Appropriate protections matter, but procedures may need to consider practical capacity.

面接想定Q6

Question: Can the ILO’s 57.9% estimate describe a specific person?

Model answer: No. It is a global population statistic about employed people, not an individual legal assessment.

面接想定Q7

Question: How should policy success be measured?

Model answer: I would examine real protections and manageable costs, not merely the number of registration certificates.

面接想定Q8

Question: Can reforms guarantee lower informality immediately?

Model answer: No. Many economic and institutional factors can affect the outcome.

FAQ

非公式雇用57.9％は世界人口の割合ですか？

いいえ。2025年の世界の就業者の中で非公式雇用に従事する人の割合です。

informal employmentは失業と同じですか？

いいえ。就業しているが形式的な保護や制度の適用が十分でない場合を含む概念です。

非公式雇用であることは犯罪の証拠ですか？

そのように断定できません。非公式雇用という統計的区分と、個々の法令違反の判断は別です。
