| Expenses [Text Block] | What were the fund costs for the last year ? Share class Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Class A $ 0.74 % |
| Expenses Paid, Amount | $ 82 |
| Expense Ratio, Percent | 0.74% |
| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class A shares gained 22.29% for the year ended November 30, 2024. That result compares with a 26.12% gain for the MSCI ACWI (All Country World Index). For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-A What factors influenced results During the fund’s fiscal year, the U.S. led global markets, driven by strong consumer spending, a healthy labor market, easing inflation and a surge in exports. Overseas, Europe and Japan experienced moderate growth, while the U.K. economy contracted in September after early 2024 gains. Among emerging economies, while political uncertainty in Brazil affected investor confidence, Taiwan experienced steady growth and mainland China benefited from supportive government policies that accelerated growth in the latter part of the year. Overall, each of the fund’s sectors added positive returns to the portfolio, with information technology, communication services and industrials producing the largest gains. Likewise, consumer discretionary, financials and utilities saw returns above those of the overall portfolio. Geographically, shares of companies based in the United States and Canada were especially additive. Companies paying consistent dividends over the period also added to portfolio returns. However, in general, companies with low or no dividend yield tended to have greater capital appreciation in 2024 than those stocks with higher dividend yields. Holdings in energy, real estate and materials, while still positive, were below the portfolio’s overall return. Similarly, the fund’s holdings in companies based in the Pacific, U.K. and European regions were additive, but were below the portfolio’s overall return. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class 529-E shares gained 21.94% for the year ended November 30, 2024. That result compares with a 26.12% gain for the MSCI ACWI (All Country World Index). For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-529E What factors influenced results During the fund’s fiscal year, the U.S. led global markets, driven by strong consumer spending, a healthy labor market, easing inflation and a surge in exports. Overseas, Europe and Japan experienced moderate growth, while the U.K. economy contracted in September after early 2024 gains. Among emerging economies, while political uncertainty in Brazil affected investor confidence, Taiwan experienced steady growth and mainland China benefited from supportive government policies that accelerated growth in the latter part of the year. Overall, each of the fund’s sectors added positive returns to the portfolio, with information technology, communication services and industrials producing the largest gains. Likewise, consumer discretionary, financials and utilities saw returns above those of the overall portfolio. Geographically, shares of companies based in the United States and Canada were especially additive. Companies paying consistent dividends over the period also added to portfolio returns. However, in general, companies with low or no dividend yield tended to have greater capital appreciation in 2024 than those stocks with higher dividend yields. Holdings in energy, real estate and materials, while still positive, were below the portfolio’s overall return. Similarly, the fund’s holdings in companies based in the Pacific, U.K. and European regions were additive, but were below the portfolio’s overall return. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-3 shares gained 21.89% for the year ended November 30, 2024. That result compares with a 26.12% gain for the MSCI ACWI (All Country World Index). For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R3 What factors influenced results During the fund’s fiscal year, the U.S. led global markets, driven by strong consumer spending, a healthy labor market, easing inflation and a surge in exports. Overseas, Europe and Japan experienced moderate growth, while the U.K. economy contracted in September after early 2024 gains. Among emerging economies, while political uncertainty in Brazil affected investor confidence, Taiwan experienced steady growth and mainland China benefited from supportive government policies that accelerated growth in the latter part of the year. Overall, each of the fund’s sectors added positive returns to the portfolio, with information technology, communication services and industrials producing the largest gains. Likewise, consumer discretionary, financials and utilities saw returns above those of the overall portfolio. Geographically, shares of companies based in the United States and Canada were especially additive. Companies paying consistent dividends over the period also added to portfolio returns. However, in general, companies with low or no dividend yield tended to have greater capital appreciation in 2024 than those stocks with higher dividend yields.
