This document summarizes findings from interviews with 55 African Americans engaged in informal economic activities in Chicago and Baltimore. It explores the nature of informal work, reasons for participating, and advantages and disadvantages. Most interviewees operate unregistered, cash-based businesses like home repair, childcare, or hair styling. While some supplement formal jobs, others work informally due to inability to find formal employment or dissatisfaction with formal jobs. Reasons for participating include the need for supplemental income, a desire for independence, or to strengthen social support networks. The document discusses implications for microenterprise programs seeking to engage these potential clients.
