Panhandling income has not been well reviewed, though doing so would be beneficial for several reasons. Understanding beggar income may aid in addressing misconceptions about the activity, clarify the financial motivation for organized or forced begging, and allow for clearer comparisons to other kinds of shadow work like prostitution, binning, or selling drugs. This study presents a systematic review of panhandling income by using Preferred Reporting Items for Systematic Reviews and Meta-Analysis and PROSPERO guidelines to aid in identifying, screening, assessing, and including research that provides quantitative income information about panhandling. Income is adjusted for inflation, and international studies are converted to USD via standard exchange rate and via purchasing power parity values. Ultimately, 38 studies are included for final analysis. The 38 studies are divided into United States specific (n = 15) and all other countries (n = 23). In adjusted 2020 USD, the economic yield from panhandling is most often $2–$16 per hour, $20–$60 per day, and $200–$500 per month, substantial variation exists. Economic comparisons to other forms of shadow work and future research directions are provided.

乞讨收入尚未得到很好的审查，但出于多种原因，这样做是有益的。了解乞丐的收入可能有助于消除对活动的误解，澄清有组织或强迫乞讨的经济动机，并允许与卖淫、装箱或贩卖毒品等其他类型的影子工作进行更清晰的比较。本研究使用系统评价和元分析的首选报告项目和 PROSPERO 指南对乞讨收入进行了系统审查，以帮助识别、筛选、评估和纳入提供有关乞讨的定量收入信息的研究。收入根据通货膨胀进行调整，国际研究通过标准汇率和购买力平价值转换为美元。最终，最终分析纳入 38 项研究。这 38 项研究分为美国特定的（n = 15) 和所有其他国家 ( n = 23)。以调整后的 2020 美元计算，乞讨的经济收益通常为每小时 2-16 美元、每天 20-60 美元和每月 200-500 美元，存在很大差异。提供了与其他形式的影子工作和未来研究方向的经济比较。
