The Sri Lanka Microenterprise project is a panel survey of 600 microenterprises located in districts of Kalutara, Galle and Matara. The survey was designed to measure the recovery of enterprises following the December 26, 2004 Asian tsunami, and to measure returns to incremental capital investments. The enterprises were surveyed quarterly between April 2005 and April 2007, and again in October 2007 and April 2008. We conducted further follow-up surveys in June and December 2010. (These are the basis of the 24 February 2012 Science article.) The sample includes enterprises suffering direct damage from the tsunami, enterprises located near the coast, but not suffering damage, and enterprises located further inland. Papers that include a more detailed description of the sample and survey are linked below.

Data from the project is available on this website. Data files (compressed STATA format) and survey instrument (pdf format) are available for all 11 rounds of the survey by clicking the links below. Information which could compromise the confidentiality of the enterprises surveyed are not included in the publicly released data.
