The documented dataset covers Enterprise Survey (ES) panel data collected in Yemen in 2010 and 2013, as part of the Middle East and North Africa Enterprise Surveys rollout, an initiative of the World Bank. New Enterprise Surveys target a sample consisting of longitudinal (panel) observations and new cross-sectional data. Panel firms are prioritized in the sample selection, comprising up to 50% of the sample in the current wave. For all panel firms, regardless of the sample, current eligibility or operating status is determined and included in panel datasets. Yemen ES 2013 was conducted between March 2013 and July 2014 as part of the joint World Bank, European Bank for Reconstruction and Development (EBRD) and European Investment Bank (EIB) Enterprise Survey. Yemen ES 2010 was carried out between March and June 2010. The objective of the Enterprise Survey is to obtain feedback from enterprises on the state of the private sector as well as to help in building a panel of enterprise data that will make it possible to track changes in the business environment over time, thus allowing, for example, impact assessments of reforms. Through interviews with firms in the manufacturing and services sectors, the survey assesses the constraints to private sector growth and creates statistically significant business environment indicators that are comparable across countries. Stratified random sampling was used to select the surveyed businesses. The data was collected using face-to-face interviews. Data from 830 establishments was analyzed: 214 businesses were from 2013 ES only, 338 from 2010 ES only, and 278 firms were from both 2010 and 2013 panels.
