Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be: 
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio.

Performance Narrative [Text Block] oef_PerformanceNarrativeTextBlock
The bar chart below provides some indication of the risks of investing in the Fund by showing how the Fund’s investment results have varied from year to year. The following table shows how the Fund’s average annual total returns, for the periods indicated, compare with the Bloomberg U.S. Government 1-3 Year Bond Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.davisfunds.com or by calling 1-800-279-0279.
After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary.

Davis Government Bond Fund | Davis Series | U.S. Government Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
U.S. Government Securities Risk. Generally, government securities, like other debt securities, are interest rate sensitive. During periods of falling interest rates, the values of debt securities held by the Fund generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline. Changes by recognized rating services in their ratings of debt securities and changes in the ability of an issuer to make payments of interest and principal also will affect the value of these investments.
Davis Government Bond Fund | Davis Series | Repurchase Agreement Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Repurchase Agreement Risk. The repurchase obligation of the seller is, in effect, secured by the underlying securities. In the event of a bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses.
Davis Government Bond Fund | Davis Series | Credit Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Credit Risk. The issuer of a fixed income security (potentially even the U.S. Government) may be unable to make timely payments of interest and principal.
Davis Government Bond Fund | Davis Series | Changes in Debt Rating Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Changes in Debt Rating Risk. If a rating agency gives a fixed income security or its issuer a low rating, the value of the security will decline because investors will demand a higher rate of return.
Davis Government Bond Fund | Davis Series | Fees and Expenses Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Fees and Expenses Risk. The Fund may not earn enough through income and capital appreciation to offset the operating expenses of the Fund. All mutual funds incur operating fees and expenses. Fees and expenses reduce the return that a shareholder may earn by investing in a fund, even when a fund has favorable performance. A low-return environment, or a bear market, increases the risk that a shareholder may lose money.
Davis Government Bond Fund | Davis Series | Inflation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Inflation Risk. Also called purchasing power risk, this is the chance that the cash flows from an investment won’t be worth as much in the future because of changes in purchasing power due to inflation.
Davis Government Bond Fund | Davis Series | Interest Rate Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Interest Rate Risk. Interest rate increases can cause the price of a debt security to decrease.
Davis Government Bond Fund | Davis Series | Extension and Prepayment Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Extension and Prepayment Risk. Extension risk occurs when borrowers maintain their existing debt obligations until they come due instead of choosing to prepay them. Prepayment risk occurs when borrowers prepay their debt obligations more quickly than usual so that they can refinance at a lower rate. The pace at which borrowers prepay affects the yield and the cash flow to holders of securities and the market value of those securities.
