Bar Chart and Performance Table [Heading]	<span style="color:#000000;font-family:Times New Roman;font-size:10.02pt;font-weight:bold;text-transform:uppercase;">Fund Performance</span>
Performance Narrative [Text Block]	The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund’s performance from year to year for Class A shares. Because Class F shares are currently not available for purchase, and have therefore not commenced investment operations, no performance information is provided for this share class. The table shows how the Fund’s average annual returns compare with the performance of a selected broad-based market index, the MSCI World Index (net), over various time periods. The MSCI World Index (net) is a free-float-adjusted index that measures performance of large- and mid-capitalization companies representing developed market countries and is net of dividend withholding taxes.In addition to the broad-based market index, the table shows performance of the Linked Global Infrastructure Index-Net, which is represented by the UBS Global 50/50 Infrastructure & Utilities Index-Net from June 1, 2008 to March 31, 2015; and the FTSE Global Core Infrastructure 50/50 Net Tax Index thereafter. The UBS Global 50/50 Infrastructure & Utilities Index-Net tracks a 50% exposure to the global developed market utilities sector and a 50% exposure to global developed market infrastructure sector. The index is free-float market-capitalization weighted and reconstituted annually with quarterly rebalances and is net of dividend withholding taxes. The FTSE Global Core Infrastructure 50/50 Net Tax Index is a market-capitalization-weighted index of worldwide infrastructure and infrastructure-related securities and is net of dividend withholding taxes. Constituent weights are adjusted semi-annually according to three broad industry sectors: 50% utilities, 30% transportation, and a 20% mix of other sectors, including pipelines, satellites, and telecommunication towers. The Advisor believes that these indexes, as compared to the broad-based market index, are comprised of securities that are more representative of the Fund’s investment strategy. Past performance (both before and after taxes) is not, however, an indication as to how the Fund may perform in the future. Updated performance information, including the Fund’s NAV per share, is available at www.cohenandsteers.com or by calling (800) 330-7348. The bar chart does not reflect the deduction of sales charges imposed on Class A shares; if these amounts were reflected, returns would be less than those shown. Absent any applicable fee waivers and/or expense limitation, performance would have been lower. The table following the bar chart reflects applicable sales charges, if any.
