For decades, surveys have been the backbone of official statistics – helping us measure everything from population trends to economic activity. But response rates have been falling dramatically across the world for the past few decades. This decline is forcing statistical agencies to rethink how they collect the data we all rely on.

In this episode, we explore the shift toward multi-source data with our special guest, Dr Anders Holmberg, General Manager and Chief Methodologist for the Australian Bureau of Statistics (ABS).

What is multi-source data, how is it collected, and what are the challenges for official statistics agencies as they move to these new data sources?

Our host is Professor James Brown, Professor of Official Statistics and current head of discipline for Mathematical Sciences at the University of Technology Sydney.
