An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.Policy Research Working Paper 11119This paper compares two widely used methods for survey-ing informal enterprises: household surveys, which collect data on enterprises through household interviews, and area-based enterprise surveys, which directly target busi-nesses in specific geographic areas. By implementing both survey approaches simultaneously in two urban centers in Ghana, this study examines key differences and similarities in the characteristics of informal enterprises across these cities. The analysis reveals substantial variation in estimates of the number of informal enterprises between the two methods, with the household survey approach reporting a significantly higher count. The paper explores poten-tial reasons for these differences, focusing on design and implementation factors. The findings also suggest that both survey methods yield consistent statistics for characterizing informal businesses and identifying factors that drive their performance. Characteristics such as bank account owner-ship, sector of operation (retail), phone usage, and operating in a fixed premise outside the household are associated with higher productivity across both surveys.This paper is a product of the Development Data Group, Development Economics.
