This research is a survey of unregistered businesses conducted in Rwanda from June to July 2011, simultaneously with Rwanda 2011 Enterprise Survey. Data from 240 informal businesses was analyzed. The objective of World Bank firm-level surveys is to obtain feedback from enterprises in client countries on the state of the private sector, assess the constraints to private sector growth and create statistically significant business environment indicators that are comparable across countries. Informal survey questionnaires are a shorter, tailored to unregistered businesses, version of Enterprise Survey questionnaires. The topics include general information about a business, infrastructure and services, sales and supplies, crime, sources and access to finance, business-government relationship, assets, AIDS and sickness (for African region), bribery, workforce composition, obstacles to get registration, reasons for not registering, and benefits that an establishment could get from registration. Business owners or managers are interviewed face-to-face. The Informal Surveys are conducted using a uniform sampling methodology in order to minimize measurement error and yield data that are comparable across the world's economies.
