Factors Affecting Performance [Text Block]	How did the Fund perform during the reporting period? Vanguard Global Wellesley Income Fund slightly outperformed its benchmark composite index for the 12 months ended August 31, 2024. Global economic growth appeared relatively stable, in the low 3% range, during the period, and U.S. recession fears faded. Central banks in emerging economies and Europe lowered their interest rate targets, but the Federal Reserve held rates steady. The FTSE Global All Cap Index of stocks returned 23.01%. The Bloomberg Global Aggregate ex-USD Index of bonds returned 6.44%. All sectors in the Fund’s stock portfolio posted robust gains. Stock selection in health care, consumer discretionary, and consumer staples contributed most to performance relative to the benchmark, while financials detracted. By region, stock selection in Europe boosted relative returns, but that was partly offset by U.S. stocks lagging those in the benchmark. In the Fund’s fixed income portion, security selection was the largest contributor to performance, particularly within the consumer cyclical, transportation, and electric utility sectors. Yield-curve positioning also contributed to excess returns.

Factors Affecting Performance [Text Block]	How did the Fund perform during the reporting period? For the 12 months ended August 31, 2024, Vanguard ESG U.S. Stock ETF performed roughly in line with its expense-free benchmark. U.S. economic growth hovered around 3% on a year-over-year basis during the 12 months, quelling recession fears. The Federal Reserve kept its target for short-term interest rates above 5%, and the year-over-year rate of consumer price inflation eased to around 3%. The CRSP US Total Market Index of stocks returned 26.17%. For the Fund’s benchmark index, 10 of the 11 industry sectors posted double-digit returns. Financials and technology were the standout performers, returning a little less than 40%. Utilities, real estate, and health care were also high up on the leaderboard. Energy, which represented a very small slice of the index, finished in negative territory.

Material Fund Change [Text Block]	How has the Fund changed? The Fund's principal investment strategy was modified to add that the Fund may become nondiversified under the Investment Company Act of 1940 solely as a result of an index rebalance or market movement; and to add screens to the methodology for the Fund's target index. The Fund added nondiversification risk and sector risk as principal risks. This is a summary of certain changes to the Fund since August 31, 2023. For more complete information, you may review the Fund’s next prospectus, which we expect to be available by December 31, 2024, at https://personal1.vanguard.com/ngf-next-gen-form-webapp/fund-literature or upon request at 800-662-7447.

Factors Affecting Performance [Text Block]	How did the Fund perform during the reporting period? For the 12 months ended August 31, 2024, Vanguard Extended Duration Treasury U.S. economic growth hovered around 3% on a year-over-year basis during the 12 months, quelling recession fears. The Federal Reserve kept its target for short-term interest rates above 5%, and the year-over-year rate of consumer price inflation eased to around 3%. The Bloomberg U.S. Aggregate Float Adjusted Index of investment-grade bonds returned 7.30%. In general, Treasuries lagged the broader bond market for the 12 months. The highest total returns tended to be in midrange maturities (10 to 15 years), not the longer maturities characteristic of the Fund’s benchmark. Because the Fund invests in zero-coupon U.S. Treasuries with maturities ranging from 20 to 30 years and the prices of such securities are very sensitive to interest rate changes, its interest rate risk is extremely high. As a result, the Fund may exhibit substantial short-term volatility and is best used by long-term investors.

Factors Affecting Performance [Text Block]	How did the Fund perform during the reporting period? For the 12 months ended August 31, 2024, Vanguard ESG International Stock ETF performed roughly in line with its expense-free benchmark. Global economic growth appeared relatively stable, in the low 3% range, during the period, and U.S. recession fears faded. Central banks in emerging economies and Europe lowered their interest rate targets, but the Federal Reserve held rates steady. The FTSE Global All Cap Index of stocks returned 23.01%. For the Fund’s benchmark index, seven of the 11 industry sectors recorded double-digit gains. Technology and financials were the standout performers. Energy, which represented a very small slice of the index, finished in negative territory. While all regions turned in strong results, Europe led the way, owing in part to performances from Denmark, Sweden, the Netherlands, and the United Kingdom. Elsewhere, India, Taiwan, and Australia were high up on the leaderboard.

Factors Affecting Performance [Text Block]	How did the Fund perform during the reporting period? Vanguard Global Wellington Fund lagged its benchmark composite index for the 12 months ended August 31, 2024. Global economic growth appeared relatively stable, in the low 3% range, during the period, and U.S. recession fears faded. Central banks in emerging economies and Europe lowered their interest rate targets, but the Federal Reserve held rates steady. The FTSE Global All Cap Index of stocks returned 23.01%. The Bloomberg Global Aggregate ex-USD Index of bonds returned 6.44%. The Fund’s stock selection in financials and consumer discretionary contributed most to performance relative to the stock portion of the benchmark, but not enough to compensate for underperformance in information technology and industrials. By region, the Fund’s Japanese stocks boosted relative returns, but they were offset by its U.S. stocks, which lagged In the Fund’s fixed income portion, security selection was the largest contributor to performance, particularly within the consumer cyclical, transportation, and electric utility sectors. Yield-curve positioning also contributed to excess returns.

Factors Affecting Performance [Text Block]	How did the Fund perform during the reporting period? For the 12 months ended August 31, 2024, Vanguard ESG U.S. Corporate Bond ETF performed roughly in line with its expense-free benchmark index. U.S. economic growth hovered around 3% on a year-over-year basis during the 12 months, quelling recession fears. The Federal Reserve kept its target for short-term interest rates above 5%, and the year-over-year rate of consumer price inflation eased to around 3%. The Bloomberg U.S. Aggregate Float Adjusted Index of investment-grade bonds returned 7.30%. With yield spreads narrowing for corporate bonds, they outperformed both Treasuries and mortgage-backed securities. In the Fund’s benchmark index, bonds issued by financial institutions returned more than those issued by industrial companies. By maturity, bonds maturing in 5 to 20 years posted the strongest gains, which were in the double digits. By credit quality, corporate bonds on the bottom rung of the investment-grade ladder performed better than higher-rated bonds.
