| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? For the 12 months ended October 31, 2024, the Fund underperformed its benchmark, the MSCI All Country World Index ex USA. Global economic growth appeared relatively stable at around 3% during the period, and U.S. recession fears faded. With inflation continuing to moderate across much of the world, major central banks including the European Central Bank, the Bank of England, and the U.S. Federal Reserve began lowering policy rates. Global stocks posted very strong returns. Selection in five of the Fund’s 11 sectors hurt returns relative to the benchmark. The Fund’s holdings in financials and consumer discretionary accounted for almost all of its underperformance. Its consumer staples holdings contributed most to relative returns. Although the Fund’s returns were positive across all regions in the portfolio, they trailed those of the benchmark, with North American stocks lagging most. Selection in North America, emerging markets, Europe, and the Pacific region detracted most from relative performance. |

| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? For the 12 months ended October 31, 2024, the Fund underperformed the MSCI US Broad Market Index, its expense-free benchmark. U.S. economic growth hovered around 3% on a year-over-year basis during the period, quelling recession fears. The Federal Reserve embarked on a rate-cutting cycle toward the end of the period, and the year-over-year rate of consumer price inflation eased to around 2.5%. U.S. stocks posted strong returns. The Fund is a fund of funds, investing in six actively managed Vanguard funds selected to provide broad exposure to all segments of the U.S. equity market. Together, those funds cover the style and capitalization spectrum. Returns of the underlying funds ranged from roughly 26% for Vanguard Windsor Fund to about 47% for Vanguard U.S. Growth Fund—the only underlier to outperform its benchmark index for the period. Among the other underlying funds, four lagged and one performed in line with its benchmark. The underperformers accounted for almost half the Fund’s assets. |
