On October 16, 2015, the US Securities and Exchange Commission published a report of private fund industry statistics and trends. The SEC aggregated and anonymized data private fund advisors have submitted to the SEC on Form ADV and Form PF. The report, which the SEC intends to update periodically, reflects information reported from the first calendar quarter of 2013 through the fourth calendar quarter of 2014. Among other things, the report includes statistics about the distribution of borrowings, an analysis of hedge fund gross notional exposure to net asset value, information regarding beneficial ownership and a comparison of average hedge fund investor and hedge fund portfolio liquidity. 

The report is available at: http://www.sec.gov/divisions/investment/private-funds-statistics/private-funds-statistics-2014-q4.pdf.
