Impact Investing Trends: Evidence of a Growing Industry is the GIIN’s first-ever industry-level trends analysis on global impact investor market activity. The GIIN has conducted a rigorous annual survey of the growing community of impact investors since 2011, and this trends report was produced using data from the 2013-2015 Annual Impact Investor Surveys. This includes 62 respondents in the analysis, representing a range of geographies, organization types, and returns philosophies. Additionally, the survey data in the report is complemented by qualitative insights from five impact investors on how the market has changed in recent years and how the market will continue to evolve.
