Building project interventions on existing institutional structures, processes, and priorities. The project design included the strategy of working with statistical institutions to improve the household surveys. The strategy also included working with the statistical institutions and other key actors, such as the labor ministries and central banks, to update the occupational and industrial classification systems. Since the statistical institutions have the mandate and resources to conduct periodic household surveys, improvements to the survey instruments are highly sustainable. Likewise, since updating the classification systems is a priority to key labor market information institutions and the cost to make the changes is low, the advances to update the systems are also highly sustainable. It should also be noted that the project leveraged previous efforts supported by the International Labor Organization and other international organizations to align the household surveys and classification systems with international standards.
