The 2019 Lao PDR Informal Sector Business Survey (ISBS) data was collected by the World Bank Group Enterprise Analysis Unit. The survey covers two cities: Vientiane and Pakse. The primary objectives of the survey are: i) to understand the business demographics of the sector in the two cities, and ii) to describe the environment within which these businesses operate. A secondary objective of the survey is to provide an estimate of the number of informal businesses operating in these cities.
