This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Portfolio, a series of The Lazard Funds, Inc. (the “Fund”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and the Example below.

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The Portfolio 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 22% of the average value of its portfolio.

Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then hold or 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 Portfolio’s operating expenses remain the same, giving effect to the expense limitation agreement described above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests at least 80% of its assets in companies that the Investment Manager considers to be “quality growth” businesses, which the Investment Manager calls compounders. By “compounders” the Investment Manager means businesses that it believes can generate, and sustain, high levels of financial productivity (i.e., cash flow return on investment) while being able to reinvest to grow at similarly high levels of financial productivity.

The Investment Manager considers, among other factors deemed appropriate and relevant to a particular company, whether the company has a competitive advantage in its industry and if the Investment Manager believes the company can sustain its competitive advantage.

The Portfolio invests primarily in equity securities of non-U.S. companies, including those whose principal business activities are located in emerging market countries.

The Portfolio may invest in securities of companies across the capitalization spectrum, but generally focuses on companies with a market capitalization of $3 billion or more.

Although the Portfolio is classified as “diversified” under the Investment Company Act of 1940, as amended, it may invest in a smaller number of issuers than other, more diversified investment portfolios.

Lazard International Quality Growth Portfolio | Market Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Market Risk: The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). To the extent that such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio’s investments in such industries, market sectors, countries and/or geographic regions can be expected to be particularly affected, especially if such investments are a significant portion of its investment portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war or military conflict, acts of terrorism, the spread of infectious illness or other public health issues, social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of sanctions or other similar measures, recessions or other events could have a significant negative impact on global economic and market conditions. For example, a public health or other emergency and aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, may have severe negative impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio’s securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures taken in response to such actions), or the threat or potential of one or more such events and developments, could lead to price volatility and overall declines in the U.S. and global investment markets.

Lazard International Quality Growth Portfolio | Issuer Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Issuer Risk: The value of a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets or factors unrelated to the issuer’s value, such as investor perception.

Non-U.S. Securities Risk: The Portfolio’s performance will be influenced by political, social and economic factors affecting the non-U.S. countries and companies in which the Portfolio invests. Non-U.S. securities carry special risks, such as less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. Non-U.S. securities may also subject the Portfolio’s investments to changes in currency rates, which can make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. Non-U.S. securities may be subject to economic sanctions or other governmental actions or developments, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) or problems related to share registration, trade settlement or asset custody, which could, among other things, effectively restrict or eliminate the Portfolio’s ability to purchase or sell certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities may become worthless. In addition, as a result of trade restrictions (including tariffs) and other similar governmental actions or developments, the Portfolio may be forced to sell or otherwise dispose of foreign investments at inopportune times or prices.

Lazard International Quality Growth Portfolio | Emerging Market Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Emerging Market Risk: Emerging market countries generally have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. The economies of countries with emerging markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities of issuers located in certain emerging countries involve the risk of loss resulting from problems in share registration, settlement or custody, substantial economic, political and social disruptions and the threat or imposition of sanctions or exchange controls (including repatriation restrictions). The securities markets of emerging market countries have historically been extremely volatile and less liquid than more developed markets, thus, the Portfolio may be unable to liquidate its positions in such securities at a favorable time or price. These market conditions may continue or worsen. Investments in these countries may be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging market currencies against the U.S. dollar may occur subsequent to acquisition of investments denominated in emerging market currencies. Emerging market countries may also be more susceptible to fraud, corruption, and money laundering, which may result in negative commercial consequences in relation to the value, liquidity and tradability of investments in or related to those regions.

Lazard International Quality Growth Portfolio | Foreign Currency Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Foreign Currency Risk: Investments denominated in currencies other than U.S. dollars may experience a decline in value, in U.S. dollar terms, due solely to fluctuations in currency exchange rates. The Portfolio’s investments denominated in such currencies (particularly currencies of emerging markets countries), as well as any investments in currencies themselves, could be adversely affected by delays in, or a refusal to grant, repatriation of funds or conversion of currencies. Irrespective of any foreign currency exposure hedging, the Portfolio may experience a decline in the value of its portfolio securities, in U.S. dollar terms, due solely to fluctuations in currency exchange rates. The Investment Manager does not intend to utilize foreign currency contracts for the purpose of generating investment returns.

Lazard International Quality Growth Portfolio | Growth Investing Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Growth Investing Risk: Growth investments are believed by the Investment Manager to have the potential for growth, but may not realize such perceived potential for extended periods of time or may never realize such perceived growth potential. Such securities may be more volatile than other securities because they can be more sensitive to investor perceptions of the issuing company’s growth potential. These securities may respond differently to market and other developments than other types of securities.

Lazard International Quality Growth Portfolio | Small and Mid Cap Companies Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Small and Mid Cap Companies Risk: Small and mid cap companies carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The shares of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

Lazard International Quality Growth Portfolio | Large Cap Companies Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Large Cap Companies Risk: Investments in large cap companies may underperform other segments of the market when such other segments are in favor or because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Lazard International Quality Growth Portfolio | Focused Investing Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Focused Investing Risk: The Portfolio’s net asset value may be more vulnerable to changes in the market value of a single issuer or group of issuers and may be relatively more susceptible to adverse effects from any single corporate,

industry, economic, market, political or regulatory occurrence than if the Portfolio’s investments consisted of securities issued by a larger number of issuers.

Lazard International Quality Growth Portfolio | Securities Selection Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Securities Selection Risk: Securities and other investments selected by the Investment Manager for the Portfolio may not perform to expectations. This could result in the Portfolio’s underperformance compared to other funds with similar investment objectives or strategies.
