What is the nutritional status of children in your town? How many tourism and hospitality companies are in your community? Answering these questions at a small scale seems like a challenge. However, imagine scaling this to a country, with one hundred and twenty three municipalities, 26 states and a federal district. Answering these questions with survey methods is the focus of this episode of Stats+Stories with guest Pedro and Denise Silva.
