Thanks for the kind words! We've been learning and growing at a fantastic rate over the last 2 years and supporting others to use our data is a priority for us. To help with growing demand, we'll be launching new on-line tools to support users in the coming months, which among other things will make it easier for you to see frequently asked questions and to learn from other users' experiences. I lead the Client Services team in the Data Group, and I've dropped you an email separately to see if I can help with your query. A key issue that affects data coverage and availability is the constraint on the statistical and data capacity of countries, and we do work with the global community to support efforts to make improvements. A good place to learn more about this issue is the PARIS21 partnership at http://www.paris21.org we also monitor statistical capacity at http://data.worldbank.org/data-catalog/bulletin-board-on-statistical-capacity.
