The problem
Collecting data from thousands of enterprises is not enough on its own. Different sectors, different firm sizes and all 81 provinces have to be represented together.
Our approach
In the World Bank / KOSGEB study the national sampling structure was handled together with the field organisation. A field operation reaching 11,062 enterprises across 81 provinces used CAPI-based collection and a multi-dimensional control approach.
Analytical perspective
Access to finance, the competitive environment, employment preferences and digital and green transformation were examined inside the same enterprise data structure, which allowed those themes to be read against one another rather than as separate surveys.
What it taught us
A large sample is not strong research on its own. What matters is structuring a large sample correctly.
