The Community Investment Explorer is a new tool to analyze community development transactions over the past 30 years. The data, sortable by year, investment purpose, and metropolitan area, comes from 3 sources: the work of CDFIs, New Markets Tax Credit (NMTC), and Low-Income Housing Tax Credit (LIHTC). "We know there [are] a lot of groups, be it affordable housing, developers, CDFIs, tax credit investors, in addition to policymakers, interested in this information and to see the stories this data tells," said a community development specialist at the Federal Reserve Bank of St. Louis.
