The Institute is the primary source for statistical data on the investment company industry.

Institute members represent 95 percent of the total investment company industry's assets. Many ICI statistical releases include not only ICI member data, but also nonmember data from the remaining 5 percent of investment company industry assets.

Institute research examines such topics as shareholder demographics, trends in shareholder ownership costs, the industry's role in foreign markets, and analyses of the retirement market.

A good overview of ICI statistics and research on mutual funds and other investment companies through the most recent year-end is the Investment Company Fact Book.
