ERC Socsemics – Dataset description Impact Investing - Global Dataset - retweet graphs 2008-22

The present dataset stems from the collection in October 2021, through an academic access to the Twitter API, of all tweets ever published that mention any term belonging to a manually defined set of English keywords relevant to the topic of impact investing (II): namely, {impactinvest*, impactbond*, impactfinance, socialfinance, #impinv, #socialimpactbonds}. We gathered a total of 1.89 million “relevant tweets”, published between 2007 and 2021, corresponding to 299 thousand unique users. We then reduced this volume and focused on accounts that were sufficiently active on the topic, or had a minimal audience, in order to capture actual participants to the II social world.
